Visit the 2-port PCI card manufacturer's web site and look for an updated
driver. If the most recent driver doesn't solve the problem, return the card
and get one that is known to work correctly with XP. I'll be happy to

Subject: [TowerTalk] Additonal Comm Port
I know this isn't exactly tower related but I'm guessing some of you here
may have already gone through this and my have some helpful advice to my
I'm trying to connect a second rig to my computer but my computer only has
one comm port on the main board. So I need to add another comm port. So I
went out and bought a 2 port PCI card. And figured it would be simple. Well
I installed the card and the driver no problem. The new ports are comm 4
and comm 5. I connect the serial cable to the new rig and as soon as I turn
the rig on my computer locks up.
My old rig works fine on comm1 and I can connect the new rig to comm1 and it
also will work fine. But I don't want to keep swapping cables to use each
radio, thus the second comm port.
So I'm guessing that either the software driver is not compatible with
WinXP or I have a resource conflict somewhere. However, Device Manager does
not show any conflicts. I'm also guessing that that is true until I turn on
the second rig. But then it's too late to troubleshoot because I'm locked
up. Only fix is cold restart. So, before I pull the card and return it I
thought I'd querry the knowledge base here.
I thought the expansion card and driver software would be smart enough to
install itself and not cause a conflict. Duh! One note is that the driver
is not digitally signed so that could be the problem there I don't know.
Anyway if anyone has experience with this I'd appreciate any helpful
advice. Please respond off-list thanks.
