I just installed a new server and upgraded from 2003 SBS to 2008 SBS. I have an EXTERNAL fax/data modem US Robotics Courier that worked well on the 2003. I see the modem in device manager, but when I attempt to query the modem, I am told that something else is using COM1. That is the ONLY com port showing in device manager. How do I determine what is opening the port... or create a new port to get this working?
