32. DATALOGGER COMUNICATION PROTOCOL
Commands format for comunication protocol for DataLogger
In the protocol management the host program sends a command containing an information request (read commands)
or the setting of a parameter (write commands).
The Manometer checks the message format and if valid it executes it and sends a reply string.
In case of error the command is not executed and no answer is provided.
The commands to manage the Datalogger communication protocol are ASCII strings of 8 characters: LCXXXXX<cr>
where: L
