Hi,

Please test the application on a device instead of the emulator. Let me know if you still experience the issue.

I have exactly the same problem. I am using .NET CF 2 on Windows Mobile 5. If I try to open COM7 with the following code I also get an IOException:

SerialPort port = new SerialPort("COM7", 4800);
port.Open();

I paired my device with bluetooth outgoing port com7 and assigned it to the gps program port.
