Unable to renumber ports on 8-port acceleport

0 votes
Hi, I installed an acceleport 8port on a pc and xp recognized it ok. The problem is the ports show up in device manager as com11 thru com 18. When I attempt to renumber to Com3 t, a message pops up saying port is in use. I suspect a digi board was previously installed that is acting as a phantom board and "claiming" these ports.

In device manager, I checked "show hidden devices" but don't see the phantom board.

So, I'm stuck on how to proceed next.

I believe you are correct in your assesment. If any previously installed serial card was removed without uninstalling the drivers first, you can have these phantom ports.
