With no modifications, the sample program in this appendix can run in BASIC BASICA*,
QuickBASIC*, and GWBASIC* on the IBM PC*, PC/XT, or PC/AT or compatibles.
The program sets up a communication channel between the IBM PC and the TCS, and creates
three touch targets centered vertically on the TCS display. Touching any target reverses the video
in the target. Touching another target causes the first to revert to normal video, and reverses the
one touched. Use Ctrl/Break to exit the program.

A null modem cable is required to connect the TCS to the host IBM PC. If a cable is not
immediately available, construction details follow. The sample program assumes the TCS is
connected to the PC serial port COM1.
