2. If a subsystem (rotator, secondary/tertiary mirror, dome) loses comms with ServoSCommunicator, a (pinkish) red warning box will appear in that subsystem's GUI complaining of Bad Comms. The first fix to try is to click on the relevant warning box. If it doesn't clear, navigate to the appropriate subsystem's tab in the ServoSCommunicator GUI and reselect the port from the dropdown list. The ports are as follows:
* Rotators: /dev/ttyUSBRot2
* Secondary & tertiary mirrors: /dev/ttyUSBFoc3
