I guess you are right that we learned something from running the driver
stand alone - but the debug level didn't seem to add as much verbosity
as it did with other drivers. I have checked on your suggestions:

I checked the bios settings - and they look right to me. The first port
used IRQ4 and the second IRQ3. To try to eliminate the possibility that
I am connecting to the wrong port - I also disabled each of the ports
(one at a time) and rebooted and re ran the Belkinunv driver. In all
cases I got exactly the same response.
I looked for /etc/modules.conf - but couldn't find this file. I'm not
sure what that means. Maybe Centos used a different system?
> Another thing could be that the serial cable used is broken.
The serial cable was working a few days ago using the Belkin supplied
software on another (older) linux centos 4.5 system.
Thanks again for all your help here Arjen. I now do have a solution
using USB - but I t6hoght I should try to get to the bottom of the
serial problem while I have the linux box available for testing. If you
have any more ideas on the serial port - please let me know.
