@xft out of curiosity: what is your use case? Is this needed for RS485 to Ethernet adapters?

@andig This is very popular case for 485-Ethernet (485-GPRS) gateways! I also need.

:-O Does somebody actually need this?

I don't think this project is being maintained any more, but if you submit this as a pull request against github.com/wz2b/modbus I'll merge it in

@wz2b I had ported the change (and some others) to the grid-x fork and wasn‘t aware of yours. Do you see any avantages over grid-x?

No, i just wasn't aware of this one ... I have one bug fix. I'll pull request it there.

That's my use case (just not ASCII).

I have a power logic cm4200 with ethernet, and 20 or so square d smart circuit breakers. The cm4200 acts like a gateway, with one address for itself and one for each breaker. I also have an SMA Sunny WebBox set up similarly ... One device addr for itself, and one for each inverter, 9 addresses total.

Hi guys, is there any chance to get RTU over TCP connection?

I‘ve ported this PR over to grid-x/modbus.
