Help....  I am looking for any possible assistance.

We have some PC's that are running a software product called Reflection, Hewlett-Packard
emulation software, that are getting garbage characters on the screen.  The facts concerning
the PC's and their configuration follow;

1. All of the PC's are connected to the Hewlett-Packard 3000 via a serial port, either Com1
or Com2. (the PC's are both Zenith 386sx's and DTK's each running at least 4MB ram)
2.  The pc's are also connected to a Novell 3.11 LAN and to the campus's backbone network
via ethernet.  We are running Clarkson Packet drivers to connect to the Novell server and
still have connectivity to IP software that we are also using. (ethernet cards are both Western
Digtial and 3Com)
3.  The Hewlett-Packard is the Model 3000, 980/100, running the 3.0 operating
environment. (Please bear with me as I am not an expert when it comes to the HP3000.)
4.  When we experience the garbage on these PC's the users can disconnect the network card
and the garbage goes away.
One of our staff thinks that the problem is related to the IRQ's of the Serial Prot and the
ethernet card.  He feels that since the network card is at IRQ 5 and the com port is at IRQ 3
that the network card is somehow invading into the com port and causing the garbage.

What makes the problem even worse is that it doesn't occur all of the time it is very
intermittent.

Any suggestions?????  Post or send directly to me.
