kbhit() in MicroSoft 'C' and Turbo'C' returns 0 if there is no character to
read from the keyboard, and 1 if there is. This could be simulated by using
one of the BIOS interrupts (INT 16 with AH = 1) or some appropriate INT 21
DOS function. It is better to use the direct calls to the BIOS PROM's, since
calling via DOS means that raw input (if you use it) is partly risky - DOS
calls check for CTRL-BREAK, CTRL-C, CTRL-P, CTRL-S and CTRL-Q, which you
dont want if you go raw. The BIOS routine does no such checks.

Also, I would like those of you who port PCcurses to other compilers to
send diff listings to me and/or Steve Creps (creps@silver.bacs.indiana.edu)
so we can have ONE reference version.
