How Can I Tell What is Using COM1 on 2008 SBS?

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?

I will need to be onsite in order to try that solution.  One thing that I forgot to mention in my original question is that this external modem connects to a serial port on the server... there ARE NONE.  I am using a serial to USB converter to connect the modem.  I don't know if this makes any difference or not....
 
Thanks again.

I installed the application on the server, and received an error that this had to be done remotely....  Is there something I missed?

I can log into the server through Terminal Services, which is how I am connecting now... I am trying to get an EXTERNAL US Robotics Courier modem installed and configured to the 2008 SBS.  I can't query the modem without getting a message that something else is using com1.  I can't seem to figure out what that IS !  Frustrating!
 
Thanks for your attention...

The error I was receiving was due to the serial to usb converter, it seems.  I have ordered one specifically compatible with 2008 server and 64 bit rather than the one that I was using that stated ALL operating systems and 32/64 bit.  I will let you know how it works once it arrives.  Had to order it from Florida, and the client ordered it GROUND.. I hope this works!
Thanks again.

I apologize for not responding sooner.  With this awful installation, my client did not renew my contract, nor did they pay me.  I thank you all for your suggestions and attempts to help me solve this issue.  Unfortunately, nothing worked.
