 *
 * 3) Feed the interpreter with characters received from your serial port.
 *    Note: Cmdb self does not retrieve input it must be handed to it.
 *    It implements basic members for checking/reading the serial port.
 *
 * 4) Handle commands added by the application by the Cid and parameters passed.
 *
 * Note: Predefined commands and all subsystems transitions are handled by the internal dispatcher.
 * So the passed dispatcher only has to handle user/application defined commands'.
