+ AA6YQ comments below
I've recently started encountering the infamous "Invalid Port Number (8002), thePort = primary CAT port, port number = 4, settings = 115200,N,8,1" message box when trying to start Commander. Device manager shows COM4 to be up and working. Unplugging / re-plugging the USB cable and disabling / reenabling the COM port doesn't resolve it. The only solution seems to be to uninstall the device, reboot and let Windows reinstall it. Then the port will open fine until the machine is rebooted again. Then we're back to invalid port and the need to reinstall.
+ Commander is attempting to open the specified COM port. Windows is responding with " Invalid Port Number (8002)", which Commander then reports to you. The error message means that either the specified COM port does not exist, or it has already been opened by another application.
+ What make and model device is responsible for creating the COM port?
+ Which other applications are running at the time the error is reported?
