Question : Problem: how can detect which devise is using Com1 ?

Windows 2K3, Citrix PS 4.0
I would like to make Com1 available for a particular device. It doesn't show up as part of the available coms in device manager, which i am assuming means that a device is usinbg it.
1) How can i detect who is using it.
2) How can i switch the device that is using it to use a different Com so i can use Com1 ?

Please reply ASAP.

Thank you!

the FIRST thing you need to do is go into the system BIOS -- COM1 is almost always on the motherboard -- so look for the BIOS setting on devices or peripherals, and you will see a COM port that is attached to the mobo.  This should be COM1, if it is not, set it to COM1.  Save the BIOS, then reboot, then you might need to follow the above suggestions.
