                          TC: int bioskey( int cmd )


       - prototype in bios.h

       - keyboard operations
       - cmd   = 0  return next keystroke w/o echo  (INT 16,0)
               = 1  test if key waiting;  0=none  (INT 16,1)
               = 2  return shift key status  (see INT 16,2)


       - AND returned value with 0x00FF to get ASCII value
       - Ctrl-Break causes "while (!bioskey(1))" to loop infinitely in
         Turbo C 2.0 and earlier since it places a zero in the keyboard queue
       - MS C uses _bios_keybrd()
       - see   INT 16
