Such a long time passed and still no information about it ? Don't we have anybody here who was active in developing the serial modbus plugin?
Let's hope that this wasn't just a placeholder for never realized future plans.
I am really interrested in a way to have two Modbus lines, because I have one IO device that is limited to 19.200 baud and I cannot drive all my VFD parameters with this low bandwidth. So two buses 19k2/115k2 would really help me.
