Someone suggested that I use KBDTRF_FINAL_CHAR_IN instead of 0x40, but I know
the following works for me (and I haven't tried his suggestion yet).
---cut here and say thank you---
/*
 * kbhit()
 *
 * Implimention of the above library call.
 *
 * Replaces the broken implimentation of kbhit() found in the Watcom C/386 9.0
 * libraries.
