I've got a Raspberry Pi3 Server and I would like to setup modbus with serial RTU connection from the Pi3 GPIO and or with USB/RTU converters. (I have more than one serial system I need to connect to.)
I'm only missing one thing, and perhaps it's rudimentary, but Where's the edit box for me to apply the com port in studio? (pics below) Am I stuck currently running IR.GetDevice commands to set the Port/Port Names?
I'm looking for a place to setup port names such as /dev/ttyS0 or /dev/ttyS1
Thank you for your help!
