# 36.8. `tty` — Terminal control functions

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])

  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])

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