INT 21 - DOS - CLEAR KEYBOARD BUFFER
        AH = 0Ch
        AL must be 01h, 06h, 07h, 08h, or 0Ah.
Notes:  flushes all typeahead input, then executes function specified by AL
          (effectively moving it to AH and repeating the INT 21 call).
        if AL contains a value not in the list above, the keyboard buffer is
          flushed and no other action is taken.
