But there is absolutely no way for the Arduino to receive a multi-byte constant over the serial port, so nothing it ever receives will be equal to that multi-byte constant.
OK. In that case what characters could be assigned as the SOP and EOP in the following format of the result code?
device 1 device2
E.g
\r\n +INQ:00:12:39:00:34:35,”RLMobile”,00:13:45:46:99:23,”Jeny”, 00:12:39:00:34:35,”RLMobile”,00:13:45:46:99:23,”Jerry”\r\n
