Actually, you will get a response if you have the wrong IRQ, because the
Linux serial driver will poll the buffer every several seconds.
The problem comes when there is more data than a simple at and response.
The card lifts an IRQ line, but the driver doesn't respond to it because it
is listening on another IRQ.
This could definitely, be a PnP problem.
