The RS232 serial control structure of the Maestro X series is a string of
hexadecimal values with a minimum of six bytes. When issuing a command,
the structure of the string is as follows: Start Transmission, Zone Number,
Command Code, Data Length, Data and End Transmission. We will use an
abbreviated form for easy reference in the following format:
<ST><ZN><CC><DL><Data><ETR>
