We are in manufacturing of EMC products.

We control our few equipment through computer. We have
used RS232 (COM1 OR COM2) as interface port. We have
developed our own application to run these equipment in
Visual Basic. Some applicaions are developed in older
versions of VB. We also include graphics server as a
supporting application. We have used graphics server 4.0
(which supports 16 bit windows).

Now our problem is when we connect one of these equipment
through RS232 port in Win 95 and Win 98 it works fine and
RS232 responds fine. But when we connect this equipmnt
through RS232 port in Win XP RS232 port slows down and
equipment do not work.

Please help us.

What exactly do you mean by *port slows down*?

I've some issues with serial ports and Win XP not all of which I found
solutions for.
