+DESCRIPTION:
+    ``CONFIGURE_APPLICATION_NEEDS_SIMPLE_CONSOLE_DRIVER`` is defined if the

+
+NOTES:
+    This device driver is responsible for providing standard input and output
+    using */dev/console*.
+
+    This device driver writes via ``rtems_putc()`` and reads via
+    ``getchark()``.  The Termios framework is not used.  There is no support to
+    change device settings, e.g. baud, stop bits, parity, etc.
