I was looking forward to hearing a good report from you.

Have you also made sure that there is not an address conflict, in
addition to making sure that there is not an IRQ conflict. Look
at every device. Where is its starting address, and how many address
locations does it use. Make sure there are no overlaps, not just
that there aren't any identical starting addresses. Check your
docs to see how many addresses each device needs.

If the DynaStore on the P233 is sending data, then you should be
able to "see" it on the P3/500. On the P3/500, start MS Windows
Hyperterminal on the com port that DynaStore is supposed to be
talking to. If DS is sending any byte stream, the Hyperterminal
screen should be dumping characters (not necessarily "printable"
characters) continuously. (This works with my BMI box.) If
Hyperterminal does not spew forth, then DS is not sending anything
for some reason.
Check the null modem cable itself. If you have a meter, make sure
all pins are properly connected for null modem use. You do have a
cable that claims to be a null modem cable, right? If you do not
have a meter that will show electric connectivity, you can always
rig one with a few pieces of wire (straightened paper clips), a
flashlight battery, and a flashlight bulb.
If the cable is working properly, then a Hyperterminal session on
each of your computers should talk back and forth. In other words,
any keystroke typed on one computer should show up on the other
computer's screen.
It's possible that the MultiTech card died of infant mortality,
or maybe you shorted it out with cable connections and disconnections
with one or both of the computers turned on. I've had very positive
results with other MultiTech products and their support over the years.
Perhaps they would send you a replacement card for testing.
Have you given up too fast with TS4 itself? Mine does not always
sync up with my BMI box when I start the server. If it starts
its routine of trying to sync by changing baud rates, I exit it
and immediately restart it again. Sometimes it take 3-4 shots to
get it to sync. I've never had it sync up, if it does not sync
immediately.
