Hi
Sounds better …
The Binding can read the config file now and shold work … but it cant open the serial port.
I am on a long weekend and have no openhabserver to test but i searched a little bit …
There is no sample for the .cfg file so …
Maybe try with the nano editor like before:
culintertechno:device=serial:/dev/ttyUSB0
culintertechno:baudrate=38400
culintertechno:parity=none
culintertechno:data=8
Have found it here:
https://community.openhab.org/t/intertechno-binding/4812/15
In the description of the intertechno binding you can find the following:
When using a serial port, you may need to add -Dgnu.io.rxtx.SerialPorts=/dev/ttyACM0 in your server startup.
This should open the serial port on server start but i cant recall/remeber the steps without try it on my openhab.
If you cant get it to work i will test it on monday.
But we can test the binding by open the port by hand 
Its not a real solution because on a reboot the port will be closed again but for now it should work.
Get to the commandline und type:
# Setup the Port
stty -F /dev/ttyUSB1 38400 raw -echo
# Open the Port / Connection with a cat terminal in background
cat /dev/ttyUSB1 &
Now try it again … the port is open so the binding should work (if you dont get in other problems).
