I wish I could have found the answer in the docs somewhere, but louie was
kind enough to help me and here is his reply (I haven't tried it yet (am
at work) but don't doubt that it is correct).  Thank you louie!

In article <3930@blake.acs.washington.edu> you write:
>	Wait(timerport->mp_SigBit);
>This does not work (hangs), but 
>	WaitPort(timerport);
>does work properly.

Wait() takes a bit mask, not a signal bit number.  So you should have used:

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

To wait for more than one signal bit, just OR the bits together:

	what = Wait((1L<<timerport->mp_SigBit) | (1L<<consoleport->mp_SigBit));

Wait() returns a bit mask of which signals occured and caused it to wake up.
