i suceeded to parse data using a rs232 adapter and node-red-node-serialport. However, the goal is to parse data over tcp, tried using tcp-node but then i cannot setup 7O1 in flow.... suggestion? virtualcom?
HOWEVER, this works and i got readings using python..
sudo socat pty,link=/dev/ttyNET0,waitslave tcp:192.168.1.238:23
sudo chmod 666 /dev/ttyNET0
dmm read --connect /dev/ttyUSB8 --count 0
sudo picocom -b 2400 /dev/ttyNET0
...but someone maybe have a flow that do that in node-red already?
I may be wrong here but I don't believe your Python example is reading over TCP - not directly, you set up a serial port that reads over TCP didn't you and then read from that serial port? Wouldn't that also work in node-red? You would still set up the port at the OS level.
