Hi!

I'm trying to detect when the user hits the keyboard. 
Unfortunately the kbhit() function is always true 
after the first key has been hit. Therefore I'm not able to
detect any further hits.


I've tracked down my problem to the following program:

#include <stdio.h>
#include <stdlib.h>
#include <pc.h>                     
#include <dos.h>

int main (void)
{  while(!kbhit())    // Wait until key pressed
   {  printf(".");
      delay(1000); }
   printf("\n");
   while (kbhit())    // Wait until key released
   {  printf("+");
      delay(1000);}
   exit(0);
}

As you coud see the program should exit after a key is pressed and
released.
But the programm is still running in the second loop.

Perhaps someone could help me with this problem.

Thanks in advance.
