I have not yet found a way to trigger interrupts.

My alternative is to use a pin on the serial port as the interrupt line.  
My electronics are simple enough that it is possible for any event that
needs to trigger an interrupt to toggle the DSR line on the serial port.  
This does generate an interrupt (which is handled by the serial driver)  
which in turn tells my code to poll the NI card.  Although this is a
little more complex (and ties up a serial port), it works quite well.

I would very much like the card to be able to trigger interrupts directly 
from state changes!  But I have found no way for this to happen :(
