Millisecond timing is possible, but don't forget ADB only gets polled
every (11 or 14)ms.  I can't remember the actual numbers but it is a lot
more than a millisecond.  In implementing Mac MEL (from PST) we
basically had the same problem.  If you really need accuracy then you
should read from a response box hangging off the serial port or the SCSI
port.  I hope this helps.
