Yep. Guess I went brain dead for a period of time.

I wasn't talking about the uart here. What I was getting at was that the 
modem had a buffer in it and sent the data to the printer port in burst. Then 
the printer port would only issue 1 IRQ for all the bytes it gets. I would 
assume that it can get more than 1 byte per IRQ. No?
