 * DESCRIPTION: This is a simple test program for IBMCOM.  It acts like a    *
 *              dump terminal at a fixed speed with no commands except Alt-X *
 *              to exit the program.  Obviously it doesn't test all of       *
 *              all of IBMCOM, but it tests the most important parts --      *
 *              receiving and sending characters.                            *
 *                                                                           *
 * REVISIONS:   18 OCT 89 - RAC - Translated from the Pascal.                *
