Note: Checksum is calculated by adding each byte in the message (including all characters from <STX> up to and
including the error log/reason indicator), such that carries are discarded to give a one byte result. The ASCII-coded
decimal representation of that byte is given, ranging from 0 (0x30, 0x30, 0x30) to 255 (0x32, 0x35, 0x35).
