What devices interrupt the CPM and which ones interrupt the SIU?
I don't recall any ATM interrupts that use the SIU, I thought they
all were CPM interrupts through the device that holds the BDs,
like SCC4 for example.

That's correct. Ensure the interrupt vector numbers you prgrammed into
the devices match the ones you are passing to the handler installer,
then ensure you have the transmit/receive interrupts enabled on the
device. Of course, there is lots more setup of the device, especially
for ATM, than simply enabling interrupts.
