- *
- * MODULE DESCRIPTION:
- * This module implements the RTEMS drivers for the PC serial ports
- * as /dev/ttyS1 for COM1 and /dev/ttyS2 as COM2. If one of the ports
- * is used as the console, this driver would fail to initialize.
- *
- * This code was based on the console driver. It is based on the
- * current termios framework. This is just a shell around the
- * termios support.
