To send the message with “QModMaster” a USB to RS-232 converter is used. To find out which
"COM" port it is set to, consult it in the Windows "Device Manager". The program has to be
configured identically to the server in RTU.
To send the register information, it is done in an identical way to the previous example in
MODBUS TCP.
