"tty" --- Terminal control functions
************************************

**Code source :** Lib/tty.py

======================================================================

Le module "tty" expose des fonctions permettant de mettre le *tty* en
mode *cbreak* ou *raw*.

Availability: Unix.

Puisqu'il a besoin du module "termios", il ne fonctionnera que sur
Unix.

Le module "tty" définit les fonctions suivantes :

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.

   Ajouté dans la 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.

   This clears the "ECHO" and "ICANON" local mode flags in *mode* as
   well as setting the minimum input to 1 byte with no delay.

   Ajouté dans la version 3.12.

   Modifié dans la version 3.12.2: The "ICRNL" flag is no longer
   cleared. This matches Linux and macOS "stty cbreak" behavior and
   what "setcbreak()" historically did.

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.

   Modifié dans la 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.

   This clears the "ECHO" and "ICANON" local mode flags as well as
   setting the minimum input to 1 byte with no delay.

   Modifié dans la version 3.12: The return value is now the original
   tty attributes, instead of "None".

   Modifié dans la version 3.12.2: The "ICRNL" flag is no longer
   cleared. This restores the behavior of Python 3.11 and earlier as
   well as matching what Linux, macOS, & BSDs describe in their
   "stty(1)" man pages regarding cbreak mode.
