"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.cfmakeraw(mode)

   Convert the tty attribute list *mode*, which is a list like the one
   returned by "termios.tcgetattr()", to that of a tty in raw mode.

   New in version 3.12.

tty.cfmakecbreak(mode)

   Convert the tty attribute list *mode*, which is a list like the one
   returned by "termios.tcgetattr()", to that of a tty in cbreak mode.

   New in version 3.12.

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()". The return value of "termios.tcgetattr()" is
   saved before setting *fd* to raw mode; this value is returned.

   Changed in version 3.12: The return value is now the original tty
   attributes, instead of None.

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()". The return value of "termios.tcgetattr()" is
   saved before setting *fd* to cbreak mode; this value is returned.

   Changed in version 3.12: The return value is now the original tty
   attributes, instead of None.
