Let me take a crack at this ... I think Frodo is getting a bit frazzled.
1) Plug your XM Radio into the USB port.
2) Look in your Device Manager for "USB Serial Port (COMX)". The X is the port number your XM Radio is using.
3) Then look in FP Settings1 under XM Radio. Put the COM port from above into this Com Port: box.
4) If this doesn't correct the problem, look in FP Settings2 under FrodoCam. Uncheck the FrodoCam Trigger Enabled checkbox. Also set the ComPort: to some value other than the value you put into the XM Radio settings window.
If none of the above work....punt. :lol:
Good luck! It's a great application!
