Begin()

Begin(Stream *sPort)

void begin(Stream *sPort, const commandList_t *commands, uint32_t size)

void begin(Stream *sPort, Stream *oPort, const commandList_t *commands, uint32_t size)

Initialise Commander with a Stream object for the input and output ports. Commander also needs a command list and a size variable before it can work. Optionally Commander can be initialised with a different output port (oPort). Any data printed using the print and write functions will use this port.
