Yea, you're right that's exactly what I want to do!

Thanks! I walked briefly through the thread and I find it reasonable to 
use PDUdaemon for this purpose .. It would be great if it gets revived!

I think many will have this requirement ..

A Modbus driver is not included yet but it would be an easy task to add it.

Does it use a different SSH port for each of the underlying serial port connections?. If that is the case, you will need to define the SSH_PORT on the corresponding board file at `fuego-ro/boards`. If you are using different user names instead, then you would need to set the SSH_KEY or the SSH user and password (LOGIN, PASSWORD) in the board file.

Okay, thanks - I will try this. We are using ConnectPort LTS32 .. SSH 
should be possible somehow. Until now we only used TELNET.

Just the modbus driver :)

Thanks & have a nice day!
