In view of the interest in this question, I am enclosing a very simple
and elegant solution to the problem sent by Peter Dufault which works
fine in all tty modes.
Thanks to all who responded.

#include <stdio.h>
#include <sgtty.h>
int kbhit(void)
{
int n;
if (ioctl(fileno(stdin), FIONREAD, &n) == -1)
n = 0;
return n != 0;
}
Peter
