| <h2 class="chapter">17 Low-Level Terminal Interface</h2> |
| |
| <p>This chapter describes functions that are specific to terminal devices. |
| You can use these functions to do things like turn off input echoing; |
| set serial line characteristics such as line speed and flow control; and |
| change which characters are used for end-of-file, command-line editing, |
| sending signals, and similar control functions. |
| |
| <p>Most of the functions in this chapter operate on file descriptors. |
| See <a href="Low_002dLevel-I_002fO.html#Low_002dLevel-I_002fO">Low-Level I/O</a>, for more information about what a file |
| descriptor is and how to open a file descriptor for a terminal device. |
