* Typical format of S/N is:CZPX0917X003XC13518
*
* Command operates only in farm mode, if not in farm mode, "Not in farm mode." is written to MYSERIAL.
*
* Send command ;S to serial port 0 to retrieve serial number stored in 32U2 processor,
* reply is transmitted to serial port 1 character by character.
* reply is transmitted to the selected serial port.
* Operation takes typically 23 ms. If the retransmit is not finished until 100 ms,
* it is interrupted, so less, or no characters are retransmitted, only newline character is send
* in any case.
* The command will fail if the 32U2 processor is unpowered via USB since it is isolated from the rest of the electronics.
* In that case the value that is stored in the EEPROM should be used instead.
