jasonb, see if this helps ......
If you receive a "Can't open port" or "Port already open" error message,
there is either a hardware problem, a resource conflict, or another program
(such as a fax or voice mail program) has control of the COM port.
For additional troubleshooting steps, see the:
"Could Not Open Port" Error Message
When you try to use your modem, you may receive the following error message:
Could not open port
This error message is typically the result of a resource conflict or a
program loading from the StartUp folder that opens a communication port. Use
the troubleshooting steps in the "Resource Conflicts" section earlier in
this article to resolve this error message. To temporarily disable programs
in the StartUp folder, follow these steps:
Click Start, point to Programs, point to Accessories, point to System Tools,
and then click System Information.
On the Tools menu, click System Configuration Utility.
Click the Startup tab. For programs that may control your modem, click the
programs's check box to clear it. If you are unsure whether or not a
specific program should be disabled, click to clear all of the check boxes
except for the following check boxes:
1. Try disabling Com2 in your BIOS - This should free up a IRQ
2. Resolve any conflicts in Device Manager, such as *Other Devices*, etc.
