I read that I can use a RS232 to USB converter to configure the module settings (and read errors etc?) via the module's RS232 'Diag' port rather than use SMS. Does anyone know where I can get the software/more info on this? It seems a much simpler system esp. if where your car is, when installing the module, has no signal.
To answer my own question, the 'OVMS Development
Guide v2.5.1 (16th August 2013)' goes some way to explain how the diagnostic port works...
