I am getting the same message. When I did an ASCOM diagnostics I get the error message access to COM port 3 is denied. Doesn't say why. But now I know why there is no connection. I don't understand why the commands sent via the serial port are being received.Hi Dan,
When you open up the Device Manager, do you see Com Port 3? If you do see the com port, there is no need to set the baud rate in the USB com port settings as the program sets the baud rate correctly. Also how do you know the commands sent to the serial port are being received? Are you using a DB9 Serial to USB adapter that uses an FTDI chip set?
