Neil,

We use the intelligent card from Computone in Atlanta, GA.  Their support
has been wonderful even while they went through a reorganization!  I have
talked with Sharon many times and she always seems to have the answers 
on the tip of her tongue ready to answer before I am finished with the 
question!

Intelligent cards can buffer the input from the ports before generating the
interrupt.  This is seen as an amazing increase in throughput on the 
machine in question.  In a way it looks a lot like the Intel 310 with
intelligent front end processors for serial I/O.

Last and none to helpful part is that I don't know if they support Microport
at all.  We tried their version and I gave up on Microport.
