>Auto Connect
Upon opening the TCF-S Focuser Control application the program will automatically attempt to connect to your TCF-S via the last selected COM port. If this is the first time running the program, it will use COM1. If a focuser is not connected to the last selected port, the status bar at the bottom of the program will display 'No TCF-S Found'. See the Operation section of this help file for information regarding how to select a COM port.
