C-KERMIT 8.0 UNIX MANUAL PAGE AND TUTORIAL
Frank da Cruz, Christine M. Gianone
[1]The Kermit Project, [2]Columbia University
[ [3]PDF version ] [ [4]Nroff version ]
This document is intended to give the beginner sufficient
information to make basic (if not advanced) use of C-Kermit 8.0.
Although it might be rather long for a Unix manual page (about 1600
lines), it's still far shorter than the C-Kermit manual, which
should be consulted for advanced topics such as customization,
character-sets, scripting, etc. We also attempt to provide a clear
structural overview of C-Kermit's many capabilities, functional
areas, states, and modes and their interrelation, that should be
helpful to beginners and veterans alike, as well as to those
upgrading to the new release.

DESCRIPTION [ [23]Top ] [ [24]Contents ] [ [25]Next ]
[26]C-Kermit is an all-purpose communications software package from
the [27]Kermit Project at [28]Columbia University that:
* Is portable to many platforms, Unix and non-Unix alike.
* Can make both serial and network connections.
* Can conduct interactive terminal sessions over its connection.
* Can transfer text or binary files over the same connection.
* Can convert text-file character sets in terminal mode or file
transfer.
* Is customizable in every aspect of its operation.
C-Kermit is a modem program, a Telnet client, an Rlogin client, an FTP
client, an HTTP client, and on selected platforms, also an X.25
client. It can make its own secure Internet connections using
IETF-approved security methods including Kerberos IV, Kerberos V,
SSL/TLS, and SRP and it can also make SSH (Secure Shell) connections
through your external SSH client application. It can be the far-end
file-transfer or client/server partner of your desktop Kermit client.
It can also accept incoming dialed and network connections. It can
even be installed as an Internet service on its own standard TCP
socket, 1649 [[29]RFC2839, [30]RFC2840].
And perhaps most important, everything you can do "by hand"
(interactively) with C-Kermit, can be "scripted" (automated) using its
built-in cross-platform transport-independent script programming
language, which happens to be identical to its interactive command
language.
This manual page offers an overview of C-Kermit 8.0 for Unix ("Unix"
is an operating system family that includes AIX, DG/UX, FreeBSD,
HP-UX, IRIX, Linux, Mac OS X, NetBSD, OpenBSD, Open Server, Open Unix,
QNX, Solaris, SunOS, System V R3, System V R4, Tru64 Unix, Unixware,
Xenix, and many others). For thorough coverage, please consult the
published C-Kermit manual and supplements (see [31]DOCUMENTATION
below). For further information about C-Kermit, Kermit software for
other platforms, and Kermit manuals, visit the Kermit Project website:
[32]http://www.columbia.edu/kermit/
This is a longer-than-average manual page, and yet it barely scratches
the surface. Don't be daunted. C-Kermit is a large and complex
package, evolving over decades of practice and experience, but that
doesn't mean it's hard to learn or use. Its most commonly used
functions are explained here with pointers to additional information
elsewhere.

________________________________________________________________________
SYNOPSIS [ [36]Top ] [ [37]Contents ] [ [38]Next ] [ [39]Previous ]
Usage: kermit [filename] [-x arg [-x arg]...[-yyy]..] [ {=,--,+} text
] ]
Or: kermit URL
* -x is an option requiring an argument;
* -y is an option with no argument.
If the first command-line argument is the name of a file,
interactive-mode commands are executed from the file. The '=' (or
"--") argument tells Kermit not to parse the remainder of the command
line, but to make the words following '=' available as \%1, \%2, ...
\%9. The "+" argument is like "=" but for use in "kerbang scripts"
(explained [40]below). A second command-line format allows the one and
only argument to be a [41]Telnet, FTP, HTTP, or IKSD URL.
Order of execution:
1. [42]The command file (if any).
2. [43]The initialization file, if any, unless suppressed with -Y.
3. [44]The customization file (if it is executed by the
initialization file).
4. [45]The command-line URL (if any, and if so, execution stops
here).
5. [46]Command-line options (if any).
6. [47]Interactive commands.
Some command-line options can cause actions (such as -s to send a
file); others just set parameters. If any action options are included
on the command line, Kermit exits when finished unless also given the
-S ("stay") option. If no action options are given, no initialization
or command files contained an EXIT or QUIT command, and no fatal
errors occurred, Kermit issues its prompt and waits for you to type
commands.
Bear in mind that C-Kermit can be built with selected features
disabled, and also that certain features are not available on all
platforms. For example, C-Kermit can't be built with TCP/IP support
on a platform that does not have TCP/IP header files and libraries
(and even if Kermit does include TCP/IP support, it can't be used
to make TCP/IP connections on a computer that does not have a
TCP/IP stack installed). If your version of C-Kermit lacks a
feature mentioned here, use its SHOW FEATURES command to see what
might have been excluded.
C-Kermit has three kinds of commands: regular single-letter
command-line options, extended-format command-line options, and
interactive commands.

________________________________________________________________________
OPTIONS [ [51]Top ] [ [52]Contents ] [ [53]Next ] [ [54]Previous ]
Like most Unix commands, C-Kermit can be be given options on the
command line. But C-Kermit also can be used interactively by giving it
[55]commands composed of words, which are more intuitive than cryptic
command-line options, and more flexible too. In other words, you don't
have to use C-Kermit's command-line options, but they are available if
you want to. (By the same token, you don't have to use its interactive
commands either -- you can use either or both in any combination.)
C-Kermit is generally installed in the PATH as "kermit", and therefore
is invoked by typing the word "kermit" (lowercase) at the shell
prompt, and then pressing the Return or Enter key. If you wish to
include command-line options, put them after the word "kermit" but
before pressing Return or Enter, separated by spaces, for example:
$ kermit -s ckermit.tar.gz
('$' is the shell prompt; "kermit -s ckermit.tar.gz" is what you type,
followed by Return or Enter.)
Here is a list of C-Kermit's single-letter command-line options, which
start with a single dash (-), in ASCII ("alphabetical") order.
Alphabetic case is significant (-A is not the same as -a). The Action?
column contains Y for action options and N for non-action options.
Option Action? Description
-0 N (digit zero) 100% transparent Connect state for "in-the-middle"
operation: 8 bits, no parity, no escape character, everything passes
through.
-8 N (digit eight) Connection is 8-bit clean (this is the default in
C-Kermit 8.0). Equivalent to the EIGHTBIT command, which in turn is a
shortcut for SET TERMINAL BYTESIZE 8, SET COMMAND BYTESIZE 8, SET
PARITY NONE.
-9 arg N (digit nine) Make a connection to an FTP server. Equivalent
to the FTP OPEN command.
Argument: IP-address-or-hostname[:optional-TCP-port].
NOTE: C-Kermit also has a separate FTP command-line personality, with
regular FTP-like command-line syntax. [56]More about this below.
-A N Kermit is to be started as an Internet service (IKSD) (only from
inetd.conf).
-B N Kermit is running in Batch or Background (no controlling
terminal). To be used in case Kermit doesn't automatically sense its
background status. Equivalent to the SET BACKGROUND ON command.
-C arg N Interactive-mode Commands to be executed.
Argument: Commands separated by commas, list in doublequotes.
-D arg N Delay before starting to send in Remote mode. Equivalent to
the SET DELAY command.
Argument: Number of seconds.
-E N Exit automatically when connection closes. Equivalent to SET EXIT
ON-DISCONNECT ON.
-F arg N Use an open TCP connection.
Argument: Numeric file descriptor of open TCP connection.
Also see: -j, -J.
-G arg Y Get file(s) from server, send contents to standard output,
which normally would be piped to another process.
Argument: Remote file specification, in quotes if it contains
metacharacters.
Also see: -g, -k.
-H N Suppress program startup Herald and greeting.
-I N Tell Kermit it has a reliable connection, to force streaming to
be used where it normally would not be. Equivalent to the SET RELIABLE
ON command.
-J arg N "Be like Telnet." Like -j but implies -E.
Argument: IP hostname/address optionally followed by service.
NOTE: C-Kermit also has a separate Telnet command-line personality,
with regular Telnet-like command-line syntax. [57]More about this
below.
-L N Recursive directory descent for files in -s option.
-M arg N My user name (for use with Telnet, Rlogin, FTP, etc).
Equivalent to the SET LOGIN USER command.
Argument: Username string.
-O Y (Uppercase letter O) Be a server for One command only. Also see:
-x.
-P N Don't convert file (Path) names of transferred files. Equivalent
to SET FILE NAMES LITERAL.
-Q N Quick Kermit protocol settings. Equivalent to the FAST command.
This is the default in C-Kermit 7.0 and later.
-R N Remote-only (this just makes IF REMOTE true).
-S N Stay (enter command parser after action options).
-T N Force Text mode for file transfer; implies -V. Equivalent to SET
TRANSFER MODE MANUAL, SET FILE TYPE TEXT.
-V N Disable automatic per-file text/binary switching. Equivalent to
SET TRANSFER MODE MANUAL.
-Y N Skip (don't execute) the initialization file.
-a arg N As-name for file(s) in -s, -r, or -g.
Argument: As-name string (alternative filename). When receiving files,
this can be a directory name.
-b arg N Speed for serial device. Equivalent to SET SPEED.
Argument: Numeric Bits per second for serial connections.
-c Y Enter Connect state before transferring files.
-d N Create a debug.log file with detailed debugging information (a
second -d adds timestamps). Equivalent to LOG DEBUG but takes effect
sooner.
-e arg N Maximum length for incoming Kermit file-transfer packets.
Equivalent to SET RECEIVE PACKET-LENGTH.
Argument: Length in bytes.
-f Y Send a FINISH command to a Kermit server.
-g arg N Get file(s) from a Kermit server.
Argument: File specification on other computer, in quotes if it
contains metacharacters. Equivalent to GET.
Also see: -a, -G, -r.
-h Y Print Help text for single-letter command-line options (pipe thru
'more' to prevent scrolling).
-i N Force binary (Image) mode for file transfer; implies -V.
Equivalent to SET TRANSFER MODE MANUAL, SET FILE TYPE BINARY.
-j arg N Make a TCP/IP connection.
Argument: IP host name/address and optional service name or number.
Equivalent to the TELNET command.
Also see: -J, -F.
-k Y Receive file(s) to standard output, which normally would be piped
to another process.
Also see: -r, -G.
-l arg N (Lowercase letter L) Make a connection on the given serial
communications device. Equivalent to the SET LINE (SET PORT) command.
Argument: Serial device name, e.g. /dev/ttyS0.
-m arg N Modem type for use with the -l device. Equivalent to the SET
MODEM TYPE command.
Argument: Modem name as in SET MODEM TYPE command, e.g. "usrobotics".
-n Y Enter Connect state after transferring files (historical).
-p arg N Parity. Equivalent to the SET PARITY command.
Argument: One of the following: e(ven), o(dd), m(ark), n(one),
s(pace).
-q N Quiet (suppress most messages). Equivalent to SET QUIET ON.
-r Y Receive file(s). Equivalent to the RECEIVE command.
Argument: (none, but see -a)
-s arg N Send file(s).
Argument: One or more local file specifications. Equivalent to the
SEND command.
Also see: -a.
-t N (Historical) Xon (Ctrl-Q) Turnaround character for half-duplex
connections (used on serial linemode connections to old mainframes).
Equivalent to SET DUPLEX HALF, SET HANDSHAKE XON.
-v arg N Window size for Kermit protocol (ignored when streaming).
Equivalanet to SET WINDOW-SIZE.
Argument: Number, 1 to 32.
-w N Incoming files Write over existing files. Equivalent to SET FILE
COLLISION OVERWRITE.
-x Y Enter server mode. Equivalent to the SERVER command. Also see:
-O.
-y arg N Alternative initialization file.
Argument: Filename.
-z N Force foreground behavior. To be used in case Kermit doesn't
automatically sense its foreground status. Equivalent to the SET
BACKGROUND OFF command.
Extended command-line options (necessary because single-letter ones
are about used up) start with two dashes (--), with words rather than
single letters as option names. If an extended option takes an
argument, it is separated from the option word by a colon (:).
Extended options include:
Option Description
--bannerfile:filename File to display upon startup or IKSD login.
--cdfile:filename File to be sent for display to the client when
server changes directory (filename is relative to the changed-to
directory).
--cdmessage:{on,off} Enable/disable the server CD message feature.
--help Prints usage message for extended options.
--helpfile:filename Designates a file containing custom text to
replace the top-level HELP command.
--nointerrupts Disables keyboard interrupts.
--noperms Disables the Kermit protocol file Permissions attribute, to
prevent transmission of file permissions (protection) from sender to
receiver.
Plus several other [58]IKSD-Only options.
See the [59]file-transfer section for examples of command-line
invocation.

COMMAND LANGUAGE [ [60]Top ] [ [61]Contents ] [ [62]Next ] [ [63]Previous ]
* [64]Command Files, Macros, and Scripts
* [65]Command List
C-Kermit's interactive command language is the subject of a
[66]622-page book and another several hundred pages of updates, far
too much for a manual page. But it's not hard to get started. At the
shell prompt, just type "kermit" to get C-Kermit's interactive command
prompt:
$ kermit
(/current/directory) C-Kermit>
Begin by typing "help" (and then press the Return or Enter key) for a
top-level overview, read it, and go from there. Your second command
should probably be "intro" (introduction). Note the prompt shows your
current directory (unless you tell Kermit to prompt you with something
else).
Interactive commands are composed mainly of regular English words,
usually in the form of imperative sentences, such as:
send oofa.txt
which tells Kermit to send (transfer) the file whose name is oofa.txt,
or:
set transfer mode automatic
which sets Kermit's "transfer mode" to "automatic" (whatever that
means).
While typing commands, you can abbreviate, ask for help (by pressing
the "?" key anywhere in a command), complete keywords or filenames
(with the Tab or Esc key), and edit your typing with Backspace or
Delete, Ctrl-W, Ctrl-U, etc. You can also recall previous commands,
save your command history, and who knows what else. Give the INTRO
command for details.
C-Kermit has hundreds of commands, and they can be issued in infinite
variety and combinations, including commands for:
* Making connections (SET LINE, DIAL, TELNET, SSH, FTP, CONNECT,
...)
* Breaking connections (HANGUP, CLOSE)
* Transferring files (SEND, GET, RECEIVE, MOVE, RESEND, ...)
* Establishing preferences (SET)
* Displaying preferences (SHOW)
* Managing local files (CD, DELETE, MKDIR, DIRECTORY, RENAME, TYPE,
...)
* Managing remote files (RCD, RDEL, RMKDIR, RDIR, ...)
* Using local files (FOPEN, FCLOSE, FREAD, FWRITE)
* Programming (TAKE, DEFINE, IF, FOR, WHILE, SWITCH, DECLARE, ...)
* Interacting with the user (ECHO, ASK, ...)
* Interacting with a remote computer (INPUT, OUTPUT, ...)
* Interacting with local programs (RUN, EXEC, PTY, ...)
* Logging things (LOG SESSION, LOG PACKETS, LOG DEBUG, ...)
And of course QUIT or EXIT to get out and HELP to get help, and for
programmers: loops, decision making, variables, arrays, associative
arrays, integer and floating point arithmetic, macros, built-in and
user-defined functions, string manipulation, pattern matching, block
structure, scoping, recursion, and all the rest. To get a list of all
C-Kermit's commands, type a question mark (?) at the prompt. To get a
description of any command, type HELP followed by the name of the
command, for example:
help send
The command interruption character is Ctrl-C (hold down the Ctrl key
and press the C key).
The command language "escape character", used to introduce variable
names, function invocations, and so on, is backslash (\). If you need
to include a literal backslash in a command, type two of them, e.g.:
get c:\\k95\\k95custom.ini
Command Files, Macros, and Scripts
A file containing Kermit commands is called a Kermit command file or
Kermit script. It can be executed with Kermit's TAKE command:
(/current/dir) C-Kermit> take commandfile
(where "commandfile" is the name of the command file). Please don't
pipe a command file into Kermit's standard input (which might or might
not work); if you have Kermit commands in a file, tell Kermit to TAKE
the file.
In Unix only, a Kermit command file can also be executed directly by
including a "kerbang" line as the first line of the file:
#!/usr/local/bin/kermit +
That is, a top line that starts with "#!", followed immediately by the
full path of the Kermit executable, and then, if the Kermit script is
to be given arguments on the command line, a space and a plus sign.
The script file must also have execute permission:
chmod +x commandfile
Except for the " +" part, this is exactly the same as you would do for
a shell script, a Perl script, etc. Here's a simple but useless
example script that regurgitates its arguments (up to three of them):
#!/usr/local/bin/kermit +
if defined \%1 echo "Argument 1: \%1"
if defined \%2 echo "Argument 2: \%2"
if defined \%3 echo "Argument 3: \%3"
if defined \%4 echo "etc..."
exit
If this file is stored in your current directory as "commandfile",
then:
./commandfile one two three four five
prints:
Argument 1: one
Argument 2: two
Argument 3: three
etc...
This illustrates the basic structure of a standalone Kermit script:
the "kerbang line", then some commands. It should end with "exit"
unless you want the Kermit prompt to appear when it is finished. \%1
is the first argument, \%2 the second, and so on.
You can also create your own commands by defining named macros
composed of other Kermit commands (or macros). Here's a simple
example:
define mydial {
set modem type usrobotics
set port /dev/ttyS0
if fail end 1
set speed 57600
dial \%1
if success connect
}
This shows how you can combine many commands into one command,
"mydial" in this case (you can use any name you like, provided it does
not clash with the name of a built-in command). When this macro
definition is in effect, you can type commands like:
mydial 7654321
and it executes all the commands in macro definition, substituting the
first operand ("7654321") for the formal parameter ("\%1") in the
definition. This saves you from having to type lots of commands every
time you want to make a modem call.
One way to have the macro definition in effect is to type the
definition at the Kermit prompt. Another way is to store the
definition in a file and TAKE the file. If you want the the definition
to be in effect automatically every time you start Kermit, put the
definition in your initialization or customization file (explained
[67]below).
Here's a somewhat more ambitious example:
define mydelete {
local trash
assign trash \v(home)trashcan/
if not defined \%1 end 1 "Delete what?"
if wild \%1 end 1 "Deleting multiple files is too scary"
if not exist \%1 end 1 "I can't find \%1"
if not directory \m(trash) {
mkdir \m(trash)
if fail end 1 "No trash can"
}
rename /list \%1 \m(trash)
}
define myundelete {
local trash
assign trash \v(home)trashcan/
if not defined \%1 end 1 "Undelete what?"
if wild \%1 end 1 "Undeleting multiple files is too hard"
if not directory \m(trash) end 1 "No trash can"
if not exist \m(trash)\%1 end 1 "I can't find \%1 in trash can"
rename /list \m(trash)\%1 .
}
These macros are not exactly production quality (they don't handle
filenames that include path segments, they don't handle multiple
files, etc), but you get the idea: you can pass arguments to macros,
they can check them and make other kinds of decisions, and the
commands themselves are relatively intuitive and intelligible.
If you put the above lines into your initialization or customization
file, you'll have MYDELETE and MYUNDELETE commands available every
time you start Kermit, at least as long as you don't suppress
execution of the initialization file. (Exercise for the reader: Make
these macros generally useful: remove limitations, add trashcan
display, browsing, emptying, etc.)
Kerbang scripts execute without the initialization file. This to keep
them portable and also to make them start faster. If you want to write
Kerbang scripts that depend on the initialization file, include the
command
take \v(home).kermrc
at the desired spot in the script. By the way, \v(xxx) is a built-in
variable (xxx is the variable name, "home" in this case). To see what
built-in variables are available, type "show variables" at the
C-Kermit prompt. To see what else you can show, type "show ?". \m(xxx)
is a user defined variable (strictly speaking, it is a macro used as a
variable).
Command List
C-Kermit has more than 200 top-level commands, and some of these, such
as SET, branch off into hundreds of subcommands of their own, so it's
not practical to describe them all here. Instead, here's a concise
list of the most commonly used top-level commands, grouped by
category. To learn about each command, type "help" followed by the
command name, e.g. "help set". Terms such as Command state and Connect
state are explained in subsequent sections.
Optional fields are shown in [ italicized brackets ]. filename means
the name of a single file. filespec means a file specification that is
allowed to contain wildcard characters like '*' to match groups of
files. options are (optional) switches like /PAGE, /NOPAGE, /QUIET,
etc, listed in the HELP text for each command. Example:
send /recursive /larger:10000 /after:-1week /except:*.txt *
which can be read as "send all the files in this directory and all the
ones underneath it that are larger than 10000 bytes, no more than one
week old, and whose names don't end with ".txt".

to write simple scripts for you.
Many of Kermit's commands have synonyms, variants, relatives, and so
on. For example, MSEND is a version of SEND that accepts a list of
file specifications to be sent, rather than just one file
specification, and MPUT is a synonym of MSEND. MOVE means to SEND and
then DELETE the source file if successful. MMOVE is like MOVE, but
accepts a list of filespecs, and so on. These are described in the
[70]full documentation.
Use question mark to feel your way through an unfamiliar command, as
in this example (the part you type is underlined):
C-Kermit> remote ? One of the following:
assign delete help login print rename space
cd directory host logout pwd rmdir type
copy exit kermit mkdir query set who
C-Kermit> remote set ? One of the following:

block-check receive server window
C-Kermit> remote set file ? One of the following:
character-set incomplete record-length
collision names type
C-Kermit> remote set file names ? One of the following:
converted literal
C-Kermit> remote set file names literal
C-Kermit>
This is called menu on demand: you get a menu when you want one, but
menus are not forced on you even when know what you're doing. Note
that you can also abbreviate most keywords, and you can complete them
with the Tab or Esc key. Also note that ? works for filenames too, and
that you can use it in the middle of a keyword or filename, not just
at the beginning. For example, "send x?" lists all the files in the
current directory whose names start with 'x'.

INITIALIZATION FILE [ [74]Top ] [ [75]Contents ] [ [76]Next ] [ [77]Previous
]
In its default configuration, C-Kermit executes commands from a file
called .kermrc in your home directory when it starts, unless it is
given the -Y or -y command-line option. Custom configurations might
substitute a shared system-wide initialization file. The SHOW FILE
command tells what initialization file, if any, was used. The standard
initialization file "chains" to an individual customization file,
.mykermc, in the home directory, in which each user can establish
her/his own preferences, define macros, and so on.
Since execution of the initialization file (at least the standard one)
makes C-Kermit take longer to start, it might be better not to have an
initialization file, especially now that Kermit's default startup
configuration is well attuned to modern computing and networking -- in
other words, you no longer have do anything special to make Kermit
transfers go fast. So instead of having an initialization file that is
executed every time Kermit starts, you might consider making one or
more kerbang scripts (with names other that .kermrc) that do NOT
include an "exit" command, and invoke those when you need the
settings, macro definitions, and/or scripted actions they contain, and
invoke C-Kermit directly when you don't.
To put it another way... We still distribute the standard
initialization file since it's featured in the manual and backwards
compatibility is important to us. But there's no harm in not using it
if you don't need the stuff that's in it (services directory, dialing
directory, network directory, and associated macro definitions). On
the other hand, if there are settings or macros you want in effect
EVERY time you use Kermit, the initialization file (or the
customization file it chains to) is the place to put them, because
that's the only place Kermit looks for them automatically each time
you start it.

________________________________________________________________________
MODES OF OPERATION [ [81]Top ] [ [82]Contents ] [ [83]Next ] [ [84]Previous ]
Kermit is said to be in Local mode if it has made a connection to
another computer, e.g. by dialing it or establishing a Telnet
connection to it. The other computer is remote, so if you start
another copy of Kermit on the remote computer, it is said to be in
Remote mode (as long as it has not made any connections of its own).
The local Kermit communicates over the communications device or
network connection, acting as a conduit between the the remote
computer and your keyboard and screen. The remote Kermit is the
file-transfer partner to the local Kermit and communicates only
through its standard input and output.
At any moment, a Kermit program can be in any of the following states.
It's important to know what they are and how to change from one to the
other.
Command state
In this state, Kermit reads commands from:
+ Your keyboard; or:
+ A file, or:
+ A macro definition.
You can exit from Command state back to Unix with the EXIT or
QUIT command (same thing). You can enter Connect state with any
of various commands (CONNECT, DIAL, TELNET, etc). You can enter
file transfer state with commands like SEND, RECEIVE, and GET.
You can enter Server state with the SERVER command. The TAKE
command tells Kermit to read and execute commands from a file.
The (perhaps implied) DO command tells Kermit to read and
execute commands from a macro definition. While in Command
state, you can interrupt any command, macro, or command file by
typing Ctrl-C (hold down the Ctrl key and press the C key);
this normally brings you back to the prompt.
Shell state
You can invoke an inferior shell or external command from the
Kermit command prompt by using the PUSH, RUN (!), EDIT, or
BROWSE command. While the inferior shell or command is active,
Kermit is suspended and does nothing. Return to Kermit Command
state by exiting from the inferior shell or application.
Connect state
In this state, which can be entered only when in Local mode
(i.e. when Kermit has made a connection to another computer),
Kermit is acting as a terminal to the remote computer. Your
keystrokes are sent to the remote computer and characters that
arrive over the communication connection are displayed on your
screen. This state is entered when you give a CONNECT, DIAL,
TELNET, RLOGIN, or IKSD command. You can return to command
state by logging out of the remote computer, or by typing:
Ctrl-\c
That is: Hold down the Ctrl key and press the backslash key,
then let go of the Ctrl key and press the C key. This is called
escaping back. Certain other escape-level commands are also
provided; type Ctrl-\? for a list. For example, you can enter
Shell state with:
Ctrl-\!
To send a Ctrl-\ to the host while in Connect state, type two
of them in a row. See HELP CONNECT and HELP SET ESCAPE for more
info.
Local file-transfer state
In this state, Kermit is sending packets back and forth with
the other computer in order to transfer a file or accomplish
some other file-related task. And at the same time, it is
displaying its progress on your screen and watching your
keyboard for interruptions. In this state, the following
single-keystroke commands are accepted:
X Interrupt the current file and go on to the next (if any).
Z Interrupt the current file and skip all the rest.
E Like Z but uses a "stronger" protocol (use if X or Z don't
work).
Ctrl-C Interrupt file-transfer mode (use if Z or E don't
work).
Kermit returns to its previous state (Command or Connect) when
the transfer is complete or when interrupted successfully by X,
Z, E, or Ctrl-C (hold down the Ctrl key and press the C key).
Remote file-transfer state
In this state, Kermit is exchanging file-transfer packets with
its local partner over its standard i/o. It leaves this state
automatically when the transfer is complete. In case you find
your local Kermit in Connect state and the remote one in
File-transfer state (in which it seems to ignore your
keystrokes), you can usually return it to command state by
typing three Ctrl-C's in a row. If that doesn't work, return
your local Kermit to Command state (Ctrl-\ C) and type
"e-packet" and then press the Return or Enter key; this forces
a fatal Kermit protocol error.
Remote Server state
This is like Remote File-transfer state, except it never
returns automatically to Command state. Rather, it awaits
further instructions from the client program; that is, from
your Local Kermit program. You can return the Remote Server to
its previous state by issuing a "finish" command to the client,
or if you are in Connect state, by typing three Ctrl-C's in a
row. You can tell the server job to log out and break the
connection by issuing a "bye" command to the client.
Local Server state
Like Remote-Server state, but in local mode, and therefore with
its file-transfer display showing, and listening for single-key
commands, as in Local File-transfer state. Usually this state
is entered automatically when a remote Kermit program gives a
GET command.
C-Kermit, Kermit 95, and MS-DOS Kermit all can switch automatically
from Connect state to Local File-transfer state when you initiate a
file transfer from the remote computer by starting Kermit and telling
it to send or get a file, in which case, Connect state is
automatically resumed after the file transfer is finished.
Note that C-Kermit is not a terminal emulator. It is a communications
application that you run in a terminal window (e.g. console or Xterm).
The specific emulation, such as VT100, VT220, Linux Console, or Xterm,
is provided by the terminal window in which you are running C-Kermit.
Kermit 95 and MS-DOS Kermit, on the other hand, are true terminal
emulators. Why is C-Kermit not a terminal emulator? [85]CLICK HERE to

________________________________________________________________________
MAKING CONNECTIONS [ [89]Top ] [ [90]Contents ] [ [91]Next ] [ [92]Previous ]
Here is how to make different kinds of connections using interactive
Kermit commands (as noted above, you can also make connections with
command-line options). Note that you don't have to make connections
with Kermit. It can also be used on the far end of a connection as the
remote file transfer and management partner of your local
communications software.
Making a Telnet Connection
At the C-Kermit command prompt, simply type:
telnet foo.bar.com ; Substitute desired host name or address.
telnet xyzcorp.com 3000 ; You can also include a port number.
If the connection is successful, Kermit automically enters
Connect state. When you logout from the remote host, Kermit
automatically returns to its prompt. More info: HELP TELNET,
HELP SET TELNET, HELP SET TELOPT. Also see the [93]IKSD section
below.
Making an Rlogin connection
This is just like Telnet, except you have to be root to do it
because Rlogin uses a privileged TCP port:
rlogin foo.bar.com ; Substitute desired host name or address.
More info: HELP RLOGIN.
Making an SSH Connection
Unlike Telnet and Rlogin, SSH connections are not built-in, but
handled by running your external SSH client through a
pseudoterminal. Using C-Kermit to control the SSH client gives
you all of Kermit's features (file transfer, character-set
conversion, scripting, etc) over SSH.
ssh foo.bar.com ; Substitute desired host name or address.
More info: HELP SSH, HELP SET SSH.
Dialing with a Modem
If it's an external modem, make sure it is connected to a
usable serial port on your computer with a regular
(straight-through) modem cable, and to the telephone jack with
a telephone cable, and that it's turned on. Then use these
commands:
set modem type usrobotics ; Or other supported type
set line /dev/ttyS0 ; Specify device name
set speed 57600 ; Or other desired speed
set flow rts/cts ; Most modern modems support this
set dial method tone ; (or pulse)
dial 7654321 ; Dial the desired number
Type "set modem type ?" for a list of supported modem types. If
you omit the SET MODEM TYPE command, the default type is
"generic-high-speed", which should work for most modern
AT-command-set modems. If the line is busy, Kermit redials
automatically. If the call does not succeed, use "set dial
display on" and try it again to watch what happens. If the call
succeeds, Kermit enters Connect state automatically and returns
to its prompt automatically when you log out from the remote
computer or the connection is otherwise lost.
You can also dial from a modem that is accessible by Telnet,
e.g. to a reverse terminal server. In this case the command
sequence is:
set host ts.xxx.com 2000 ; Terminal-server and port
set modem type usrobotics ; Or other supported type
set dial method tone ; (or pulse)
dial 7654321 ; Dial the desired number
If the terminal server supports the Telnet Com Port Option,
[94]RFC 2217, you can also give serial-port related commands
such as SET SPEED, SET PARITY, and so on, and Kermit relays
them to the terminal server using the protocol specified in the
RFC.
More info: HELP SET MODEM, HELP SET LINE, HELP SET SPEED, HELP
SET FLOW, HELP DIAL, HELP SET DIAL, HELP SET MODEM, HELP SET
CARRIER-WATCH, SHOW COMMUNICATIONS, SHOW MODEM, SHOW DIAL.
Direct Serial Port
Connect the two computers, A and B, with a null modem cable (or
two modem cables interconnected with a null-modem adapter or
modem eliminator). From Computer A:
set modem type none ; There is no modem
set line /dev/ttyS0 ; Specify device name
set carrier-watch off ; If DTR and CD are not cross-connected
set speed 57600 ; Or other desired speed
set flow rts/cts ; If RTS and CTS are cross-connected
set flow xon/xoff ; If you can't use RTS/CTS
set parity even ; (or "mark" or "space", if necessary)
set stop-bits 2 ; (rarely necessary)
connect ; Enter Connect (terminal) state
This assumes Computer B is set up to let you log in. If it
isn't, you can run a copy of Kermit on Computer B and follow
approximately the same directions. More info: As above plus
HELP CONNECT.
With modems or direct serial connections, you might also have to "set
parity even" (or "mark" or "space") if it's a 7-bit connection.
Of the connection types listed above, only one can be open at a time.
However, any one of these can be open concurrently with an [95]FTP or
HTTP session. Each connection type can be customized to any desired
degree, scripted, logged, you name it. See the manual.
NOTE: On selected platforms, C-Kermit also can make X.25 connections.
See the manual for details.

* [107]Advanced Kermit File Transfer Features
* [108]Non-Kermit File Transfer
There is a [109]widespread and persistent belief that Kermit is a slow
protocol. This is because, until recently, it used conservative tuning
by default to make sure file transfers succeeded, rather than failing
because they overloaded the connection. Some extra commands (or
command-line options, like -Q) were needed to make it go fast, but
nobody bothered to find out about them. Also, it takes two to tango:
most non-Kermit-Project Kermit protocol implementations really ARE
slow. The best file-transfer partners for C-Kermit are: another copy
of [110]C-Kermit (7.0 or later) and [111]Kermit 95. These combinations
work well and they work fast by default. MS-DOS Kermit is good too,
but you have to tell it to go fast (by giving it the FAST command).
Furthermore, all three of these Kermit programs support "autodownload"
and "autoupload", meaning that when they are in Connect state and a
Kermit packet comes in from the remote, they automatically switch into
file transfer mode.
And plus, C-Kermit and K95 also switch automatically between text and
binary mode for each file, so there is no need to "set file type
binary" or "set file type text", or to worry about files being
corrupted because they were transferred in the wrong mode.
What all of these words add up to is that now, when you use up-to-date
Kermit software from the Kermit Project, file transfer is not only
fast, it's ridiculously easy. You barely have to give any commands at
all.
Downloading Files
Let's say you have [112]Kermit 95, [113]C-Kermit, or
[114]MS-DOS Kermit on your desktop computer, with a connection
to a Unix computer that has C-Kermit installed as "kermit". To
download a file (send it from Unix to your desktop computer),
just type the following command at your Unix shell prompt:
kermit -s oofa.txt
(where oofa.txt is the filename). If you want to send more than
one file, you can put as many filenames as you want on the
command line, and they can be any combination of text and
binary:
kermit -s oofa.txt oofa.zip oofa.html oofa.tar.gz
and/or you can use wildcards to send groups of files:
kermit -s oofa.*
If you want to send a file under an assumed name, use:
kermit -s friday.txt -a today.txt
This sends the file friday.txt but tells the receiving Kermit
that its name is today.txt. In all cases, as noted, when the
file transfer is finished, your desktop Kermit returns
automatically to Connect state. No worries about escaping back,
re-connecting, text/binary mode switching. Almost too easy,
right?
Uploading Files
To upload files (send them from your desktop computer to the
remote Unix computer) do the same thing, but use the -g (GET)
option instead of -s:
kermit -g oofa.txt
This causes your local Kermit to enter server mode; then the
remote Kermit program requests the named file and the local
Kermit sends it and returns automatically to Connect state when
done.
If you want to upload multiple files, you have have use shell
quoting rules, since these aren't local files:
kermit -g "oofa.txt oofa.zip oofa.html oofa.tar.gz"
kermit -g "oofa.*"
If you want to upload a file but store it under a different
name, use:
kermit -g friday.txt -a today.txt
Kermit Transfers the Old-Fashioned Way
If your desktop communications software does not support
autoupload or autodownload, or it does not include Kermit
server mode, the procedure requires more steps.
To download a file, type:
kermit -s filename
on the host as before, but if nothing happens automatically in
response to this command, you have to switch your desktop
communications software into Kermit Receive state. This might
be done by escaping back using keyboard characters or hot keys
(Alt-x is typical) and/or with a command (like RECEIVE) or a
menu. When the file transfer is complete, you have to go back
to Connect state, Terminal emulation, or whatever terminology
applies to your desktop communications software.
To upload a file, type:
kermit -r
on the host (rather than "kermit -g"). This tells C-Kermit to
wait passively for a file to start arriving. Then regain the
attention of your desktop software (Alt-x or whatever) and
instruct it to send the desired file(s) with Kermit protocol.
When the transfer is finished, return to the Connect or
Terminal screen.
If File Transfer Fails
Although every aspect of Kermit's operation can be finely
tuned, there are also three short and simple "omnibus tuning"
commands you can use for troubleshooting:
FAST
Use fast file-transfer settings. This has been the
default since C-Kermit 7.0 now that most modern computers
and connections support it. If transfers fail with fast
settings, try . . .
CAUTIOUS
Use cautious but not paranoid settings. File transfers,
if they work, will go at medium speed. If not, try . . .
ROBUST
Use the most robust, resilient, conservative, safe, and
reliable settings. File transfers will almost certainly
work, but they will be quite slow (of course this is a
classic tradeoff; ROBUST was C-Kermit's default tuning in
versions 6.0 and earlier, which made everybody think
Kermit protocol was slow). If ROBUST doesn't do the
trick, try again with SET PARITY SPACE first in case it's
not an 8-bit connection.
Obviously the success and performance of a file transfer also
depends on C-Kermit's file transfer partner. Up-to-date, real
[115]Kermit Project partners are recommended because they
contain the best Kermit protocol implementations and because
[116]we can support them in case of trouble.
If you still have trouble, consult Chapter 10 of [117]Using
C-Kermit, or send email to [118]kermit-support@columbia.edu.
Advanced Kermit File-Transfer Features
Obviously there is a lot more to Kermit file transfer,
including all sorts of interactive commands, preferences,
options, logging, debugging, troubleshooting, and anything else
you can imagine but that's what the [119]manual and updates are
for. Here are a few topics you can explore if you're interested
by Typing HELP for the listed commands:
Logging transfers:
LOG TRANSACTIONS (HELP LOG)
Automatic per-file text/binary mode switching:
SET TRANSFER MODE { AUTOMATIC, MANUAL } (HELP SET
TRANSFER).
Cross-platform recursive directory tree transfer:
SEND /RECURSIVE, GET /RECURSIVE (HELP SEND, HELP GET).
File collision options:
SET FILE COLLISION { OVERWRITE, BACKUP, DISCARD, ... }
(HELP SET FILE).
Update mode (only transfer files that changed since last time):
SET FILE COLLISION UPDATE (HELP SET FILE).
Filename selection patterns:
(HELP WILDCARD).
Flexible file selection:
SEND (or GET) /BEFORE /AFTER /LARGER /SMALLER /TYPE
/EXCEPT, ...
Character-set conversion:
SET { FILE, TRANSFER } CHARACTER-SET, ASSOCIATE, ...
File/Pathname control:
SET { SEND, RECEIVE } PATHNAMES, SET FILE NAMES.
Atomic file movement:
SEND (or GET) /DELETE /RENAME /MOVE-TO
Transferring to/from standard i/o of other commands:
SEND (or GET) /COMMAND
Recovery of interrupted transfer from point of failure:
RESEND, REGET (HELP RESEND, HELP REGET).
Non-Kermit File Transfer
You can also use C-Kermit to transfer files with FTP or HTTP
Internet protocols; [120]see below.
On a regular serial or Telnet connection where the other
computer doesn't support Kermit protocol at all, you have
several options. For example, if your desktop communications
software supports Zmodem, use "rz" and "sz" on the host rather
than Kermit. But if Kermit is your desktop software, and you
are using it to make calls or network connections to other
computers that don't support Kermit protocol (or that don't
have a good implementation of it), then if your computer also
has external X, Y, or Zmodem programs that are redirectable,
Kermit can use them as external protocols. HELP SET PROTOCOL
for details.
You can also capture "raw" data streams from the other computer
with LOG SESSION (HELP LOG and HELP SET SESSION-LOG for
details), and you can upload files without any protocol at all
with TRANSMIT (HELP TRANSMIT, HELP SET TRANSMIT).

KERMIT CLIENT/SERVER CONNECTIONS [ [124]Top ] [ [125]Contents ] [ [126]Next ]
[ [127]Previous ]
On any kind of connection you can make with Kermit -- serial, TCP/IP,
X.25, etc -- you can set up a convenient client/server relationship
between your Kermit client (the one that made the connection) and the
Kermit program on the far end of the connection (the remote Kermit) by
putting the remote Kermit in server mode. This is normally done by
giving it a SERVER command, or by starting it with the -x command-line
option. In some cases ([128]Internet Kermit Service, SSH connections
to a Kermit subsystem, or specially configured hosts), there is
already a Kermit server waiting on the far end. Here is a quick
synopsis of the commands you can give to the client for interacting
with the server:
SEND [ switches ] filename
Sends the named file to the server. The filename can include
wildcards. Lots of switches are available for file selection,
etc. Type HELP SEND at the client prompt for details.
GET [ switches ] filename
Asks the server to send the named file. The filename can
include wildcards. Type HELP GET at the client prompt for
details.
BYE
Terminates the server and closes your connection to it.
FINISH
Terminates the server. If you started the server yourself, this
leaves the remote host at its shell prompt. If it was a
dedicated server (such as IKSD or an SSH subsystem), FINISH is
equivalent to BYE.
SET LOCUS { LOCAL, REMOTE, AUTO }
(C-Kermit 8.0.201 and later, K95 1.1.21 and later) This tells
the client whether file-management commands like CD, PWD,
DIRECTORY, DELETE, MKDIR, etc, should be executed locally or by
the server. In this type of connection, the default is LOCAL.
Use SET LOCUS REMOTE if you want Kermit to behave like an FTP
client, in which case these commands are executed remotely, and
their local versions must have an L prefix: LCD, LPWD,
LDIRECTORY, etc. When LOCUS is LOCAL, then the remote versions
must have an R prefix: RCD, RPWD, RDIRECTORY, etc. HELP SET
LOCUS for details. SHOW COMMAND to see current locus.
The following commands are affected by SET LOCUS:
CD, LCD, RCD
Change (working, current) directory. HELP CD for details.
CDUP, LCDUP, RCDUP
CD one level up.
DIRECTORY, LDIRECTORY, RDIRECTORY
Produce a directory listing. Many options are available for local
listings. HELP DIRECTORY for details.
DELETE, LDELETE, RDELETE
Deletes files or directories. Many options available, HELP DELETE.
RENAME, LRENAME, RRENAME
Renames files or directories. Many options available, HELP RENAME.
MKDIR, LMKDIR, RMKDIR
Creates a directory. HELP MKDIR.
RMDIR, LRMDIR, RRMDIR
Removes a directory. HELP RMDIR. There are dozens -- maybe hundreds --
of other commands, described in the built-in help, on the website,
and/or in the published or online manuals. But even if you don't have
access to documentation, you can "set locus remote" and then use
pretty much the same commands you would use with any FTP client.

KERMIT'S BUILT-IN FTP AND HTTP CLIENTS [ [132]Top ] [ [133]Contents ] [
[134]Next ] [ [135]Previous ]
Kermit's FTP client is like the regular Unix FTP client that you're
used to, but with some differences:
* It has lots more commands and features.
* You can have an FTP session and a regular Kermit serial or Telnet
session open at the same time.
* FTP sessions can be fully automated.
By default Kermit's FTP client tries its best to present the same user
interface as a regular FTP client: PUT, GET, DIR, CD, BYE, etc, should
work the same, even though some of these commands have different
meaning in Kermit-to-Kermit connections; for example, CD, DIR, RENAME,
etc, in Kermit act locally, whereas in FTP they are commands for the
server. This might cause some confusion, but as in all things Kermit,
you have total control:
* The [136]SET LOCUS command lets you specify where file management
commands should be executed -- locally or remotely -- for any kind
of connection.
* Any FTP command can be prefixed with the word "FTP" to remove any
ambiguity.
Pending publication of the next edition of the manual, the Kermit FTP
client is thoroughly documented at the Kermit Project website:
[137]http://www.columbia.edu/kermit/ftpclient.html
You also can use HELP FTP and HELP SET FTP to get descriptions of
Kermit's FTP-related commands.
The HTTP client is similar to the FTP one, except you prefix each
command with HTTP instead of FTP: HTTP OPEN, HTTP GET, HTTP PUT, HTTP
CLOSE, etc. Type HELP HTTP for details, or visit the to view the
[138]manual supplements. HTTP connections can be open at the same time
as regular serial or Telnet connections and FTP connections. So Kermit
can manage up to three types connections simultaneously.

INTERNET KERMIT SERVICE [ [144]Top ] [ [145]Contents ] [ [146]Next ] [
[147]Previous ]
C-Kermit can be configured and run as an Internet service (called
IKSD), similar to an FTP server (FTPD) except you can (but need not)
interact with it directly, plus it does a lot more than an FTP server
can do. The TCP port for IKSD is 1649. It uses Telnet protocol.
C-Kermit can be an Internet Kermit Server, or it can be a client of an
IKSD. You can make connections from C-Kermit to an IKSD with any of
the following commands:
telnet foo.bar.edu 1649
telnet foo.bar.edu kermit ; if "kermit" is listed in /etc/services
iksd foo.bar.edu
The IKSD command is equivalent to a TELNET command specifying port
1649. For more information about making and using connections to an
IKSD, see:
[148]http://www.columbia.edu/kermit/cuiksd.html
You can run an Internet Kermit Service on your own computer too (if
you are the system administrator). For instructions, see:

SECURITY [ [153]Top ] [ [154]Contents ] [ [155]Next ] [ [156]Previous ]
All of C-Kermit's built-in TCP/IP networking methods (Telnet, Rlogin,
IKSD, FTP, and HTTP) can be secured by one or more of the following
IETF-approved methods:
* MIT Kerberos IV
* MIT Kerberos V
* SSL/TLS
* Stanford SRP
For complete instructions see:
[157]http://www.columbia.edu/kermit/security.html
And as noted previously, you can also make SSH connections with
C-Kermit if you already have an SSH client installed.

ALTERNATIVE COMMAND-LINE PERSONALITIES [ [161]Top ] [ [162]Contents ] [
[163]Next ] [ [164]Previous ]
When invoked as "kermit" or any other name besides any of the special
ones, C-Kermit has the command-line options described above in the
[165]OPTIONS section. However, if you invoke C-Kermit using any of the
following names:
telnet Telnet client
ftp FTP client
http HTTP client
https Secure HTTP client
Kermit's command-line personality changes to match. This can be done
(among other ways) with symbolic links (symlinks). For example, if you
want C-Kermit to be your regular Telnet client, or the Telnet helper
of your Web browser, you can create a link like the following in a
directory that lies in your PATH ahead of the regular telnet program:
ln -s /usr/local/bin/kermit telnet
Now when you give a "telnet" command, you are invoking Kermit instead,
but with its Telnet command-line personality so, for example:
telnet xyzcorp.com
Makes a Telnet connection to xyzcorp.com, and Kermit exits
automatically when the connection is closed (just like the regular
Telnet client). Type "telnet -h" to get a list of Kermit's
Telnet-personality command-line options, which are intended to be as
compatible as possible with the regular Telnet client.
Similarly for FTP:
ln -s /usr/local/bin/kermit ftp
And now type "ftp -h" to see its command-line options, and use command
lines just like you would give your regular FTP client:
ftp -n xyzcorp.com
but with additional options allowing an entire session to be specified
on the command line, as explained in the C-Kermit [166]FTP client
documentation.
And similarly for HTTP:
ln -s /usr/local/bin/kermit http
./http -h
./http www.columbia.edu -g kermit/index.html
Finally, if Kermit's first command-line option is a Telnet, FTP, IKSD,
or HTTP URL, Kermit automatically makes the appropriate kind of
connection and, if indicated by the URL, takes the desired action:
kermit telnet:xyzcorp.com ; Opens a Telnet session
kermit telnet://olga@xyzcorp.com ; Ditto for user olga
kermit ftp://olga@xyzcorp.com/public/oofa.zip ; Downloads a file
kermit kermit://kermit.columbia.edu/kermit/f/READ.ME ; Ditto for IKSD
kermit iksd://kermit.columbia.edu/kermit/f/READ.ME ; (This works too)
kermit http://www.columbia.edu/kermit/index.html ; Grabs a web page
kermit https://wwws.xyzcorp.com/secret/plan.html ; Grabs a secure web pag

LICENSE [ [170]Top ] [ [171]Contents ] [ [172]Next ] [ [173]Previous ]
C-Kermit has an unusual license, but a fair and sensible one given
that the Kermit Project must support itself out of revenue: it's not a
BSD license, not GPL, not Artistic, not commercial, not shareware, not
freeware. It can be summed up like this: if you want C-Kermit for your
own use, you can download and use it without cost or license (but we'd
appreciate it if you would purchase the manual). But if you want to
sell C-Kermit or bundle it with a product or otherwise distribute it
in a commercial setting EXCEPT WITH AN OPEN-SOURCE OPERATING SYSTEM
DISTRIBUTION such as Linux, FreeBSD, NetBSD, or OpenBSD, you must
license it. To see the complete license, give the LICENSE command at
the prompt, or see the COPYING.TXT file distributed with C-Kermit 7.0
or later, or download it from
[174]ftp://kermit.columbia.edu/kermit/c-kermit/COPYING.TXT. Send
licensing inquiries to [175]kermit@columbia.edu.
