Hi @rossko57  
in my previous posts I explained that the serial binding works for a while and then it stops working.  
When I say that the binding doesn’t work, I mean that it’s not usable as it stops receiving messages after a while, so it’s not reliable for my needs.

To be more precise, to setup the modbus binding, I have removed all other bindings (and relevant things and rules) and set up things, items and rules for the modbus. When everything was working I reenabled all the other bindings, things and rules and then after a while the modbus stopped working.

So the serial port configuration is perfectly fine in my system. Something else is creating the issue.
