-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.

-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.
