<h3 class="section">17.4 Terminal Modes</h3>

<p><a name="index-termios_002eh-1856"></a>This section describes the various terminal attributes that control how
input and output are done.  The functions, data structures, and symbolic
constants are all declared in the header file <samp><span class="file">termios.h</span></samp>.

   <p>Don't confuse terminal attributes with file attributes.  A device special
file which is associated with a terminal has file attributes as described
in <a href="File-Attributes.html#File-Attributes">File Attributes</a>.  These are unrelated to the attributes of the
terminal device itself, which are discussed in this section.

<ul class="menu">
