Note that mp_SigBit is the BIT NUMBER and the Wait() used the bit mask so
that you can wait on multiple signals.  So...

        Wait(1L << (timerport->mp_SigBit));

or if you have a few more...

        Wait(	(1L << (timerport->mp_SigBit)) |
		(1L << (otherport->mp_SigBit)) |
		(1L << (inputport->mp_SigBit))	);
