Python: Essential Reference, Third Edition

tty

The tty module provides functions for putting a TTY into cbreak and raw modes on UNIX systems. Raw mode forces a process to receive every character on a TTY with no interpretation by the system. Cbreak mode enables system processing for special keys such as the interrupt and quit keys (which generate signals).

setraw(fd [, when])

Changes the mode of the file descriptor fd to raw mode. when specifies when the change occurs and is termios.TCSANOW, termios.TCSADRAIN, or termios.TCSAFLUSH (the default). Refer to the termios module for more description of these constants.

setcbreak(fd [, when])

Changes the mode of file descriptor fd to cbreak mode. when has the same meaning as in setraw().

Note

The tty module requires the termios module.
