Callbacks from the IrDA stack are not preemptive. IAS callbacks operate the
same as all the other IrDA callbacks. They will generally be called inside
your call to EvtGetEvent. You could block the callback by not checking for
events, but you would not want to do that for long. I can't think of any
way to know if one is pending.
