# 8.8 `TERMIOS` -- Constants used with the `termios` module

Availability: Unix.

This module defines the symbolic constants required to use the `termios` module (see the previous section). See the POSIX or Unix manual pages (or the source) for a list of those constants.

Note: this module resides in a system-dependent subdirectory of the Python library directory. You may have to generate it for your particular system using the script `Tools/scripts/h2py.py`.
