I have a Cyclades TS100 which is used to communicate with a Modbus Slave.

I selected Protocol: Modbus and configured MODBUS Serial Mode: RTU

The thing is, I event don't get a connection to the Serial Server on my selected port. What is the secret?

(The device itself works fine, even over the Serial Server, if I configure it to Socket Raw and speak to it via Modbus/RTU over TCP)

UPDATE: it seems that sometime in the past it was decided to comment out the modbus service from inetd.conf, so this was the sole reason the communication didn't work.
