Also, this is the wrong newsgroup.  Followups are redirected.

But to answer the original question:
For many cases:

	/* cheaper than buying zortech :-) */
	#include <stdio.h>
	int kbhit() { return rdchk(fileno(stdin)) != 0; }


will do, but only under Xenix and Unix SYSVR3.2 and higher, linking
with the -lx library, but this answer is good enough for the poster
of the original question.  Of course, you have to setbuf(stdin, (char *)0);
at the beginning of the program to make this work.
