Low-Level Terminal Interface
****************************
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.
Most of the functions in this chapter operate on file descriptors.
Note:Low-Level I/O, for more information about what a file
descriptor is and how to open a file descriptor for a terminal device.
