When specific bits are set (to 1), record and playback functions
will abort if the associated event is detected. The Record or
Playback routine will return the value of the bit to indicate
which event was detected. Additionally the ANSWER_DETECT
command requires that the KEYBD_INT bit be set in order to break
out of the answer detect routine with a keystroke.
