When you connect a rotator for the first time you will be asked to select the connection parameters by the standard ASCOM dialog. APT will remember your selection and when you click again on the “Connect” button it will use the previous settings automatically. If you want to change the connection parameters, use “Shift+Click” on the Connect button. Use Ctrl+Click to forget the selected connection parameters.
Opens the settings dialog of the ASCOM driver. If this action is not supported by the driver, use Shift+Click on Connect button and then click Properties in the driver selector dialog box.
