I would use Device Manager to unistall the port:
1. Control Panel-System-Hardware Tab-Device Manager
2. Open the + nex to ports-Select Com1. Click the
uninstall button. Click Ok.
3. Close all windows and reboot the pc. It will reinstall
the port automatically. It should then be released from
what ever was using it. Cheers.
