# `tty` --- Terminal control functions

Source code: Lib/tty.py

The `tty` module defines functions for putting the tty into cbreak and raw modes.

Because it requires the `termios` module, it will work only on Unix.

The `tty` module defines the following functions:

`tty.``setraw`(fd, when=termios.TCSAFLUSH)

  Change the mode of the file descriptor fd to raw. If when is omitted, it defaults to `termios.TCSAFLUSH`, and is passed to `termios.tcsetattr()`.

`tty.``setcbreak`(fd, when=termios.TCSAFLUSH)

  Change the mode of file descriptor fd to cbreak. If when is omitted, it defaults to `termios.TCSAFLUSH`, and is passed to `termios.tcsetattr()`.
