NOTES:
None.
.. COMMENT: === CONFIGURE_TERMIOS_DISABLED ===
.. index:: CONFIGURE_TERMIOS_DISABLED
.. _Disable POSIX Termios Support:
Disable POSIX Termios Support
-----------------------------
CONSTANT:
``CONFIGURE_TERMIOS_DISABLED``
DATA TYPE:
Boolean feature macro.
RANGE:
Defined or undefined.
DEFAULT VALUE:
This is not defined by default, and resources are reserved for the termios
functionality.
DESCRIPTION:
This configuration parameter is defined if the software implementing POSIX
termios functionality is not going to be used by this application.
NOTES:
The termios support library should not be included in an application
executable unless it is directly referenced by the application or a device
driver.

Specify Maximum Termios Ports
-----------------------------
CONSTANT:
``CONFIGURE_NUMBER_OF_TERMIOS_PORTS``
DATA TYPE:
Unsigned integer.
RANGE:
Zero or positive.
DEFAULT VALUE:
The default value is 1, so a console port can be used.
DESCRIPTION:
This configuration parameter is set to the number of ports using the
termios functionality. Each concurrently active termios port requires
resources.
NOTES:
If the application will be using serial ports including, but not limited
to, the Console Device
(e.g. ``CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER``), then it is highly
likely that this configuration parameter should NOT be is defined.
