How to configure node-red for two serial ports?
There should be no problem configuring two serial ports. What issue are you having?
First go to the serial node config
next select add new port and click the edit button
Fill out the path to a serial port on your host system and click add
That port will now show up in the dropdown to be selected by serial nodes
Repeat for each port as needed.
when I change com port number other configured port details are changing.
Thanks you very much
