Posted for future reference:

If you use Remote Desktop DO NOT check the setup box for the serial port under Options-Local Resources- "Connect automatically to these local resources when logged on to the remote computer". It will prevent ACP from connecting to your scope. It will give no error message and try indefinitely.

Your local machine at the scope may or may not connect.


Remote Desktop ACP Connection issues, serial port not connecting, telescope not connecting.
