                        INT 16,1 - Get Keyboard Status

       AH = 01

       on return:
       ZF = 0 if a key pressed (even Ctrl-Break)
       AX = 0 if no scan code is available
       AH = scan code
       AL = ASCII character or zero if special function key

       - data code is not removed from buffer
       - Ctrl-Break places a zero word in the keyboard buffer but does
         register a keypress.
