Not having gotten any responses to my previous 2 posts about silo overflow
on one serial port, now I have another question.  Why would I be getting
overflows when the port doesn't get used at all.  Yes, getty is running,
but no nothing dials out nor in.  Where would I start to or how to start
to look for missed interrupt on that port?  SIO card is AST-4Port, all 
with 550's in it.  Is sitting on irq2 (9), and is configured as sio 2-5.

I'd really like to be able to use it, but it's useless as it is.  The
telebit internal modem works flawlessly, sitting on irq3, as sio1.
