Thank you Dan for your help. Much appreciated.
I fiddled some more and decided to install a RS232 spy tool on the Xibo Player machine. This made it easier to check if there is some form of communication with the serial port instead of looking at the logging information.
Turned out that it was very silent on the serial port channel
With a lot of trail and error I came across an old topic on this forum that also discussed the possibility to place a Shell command as a widget into the layout directly. When I use this option it works!
Atleast I have some communication with the serial port

There payload is not there yet but when I set the HEX Support to 0 I get this;

Finally
Now I am not sure if this is a bug or the command functionality method just does not work with my combo Docker on Debian for the CMS and Windows 11 for the player? I do know that using a Shell Command Widget within the layout works for me.
If anyone has any suggestions to get the regular command functionality working I`d like to hear it.
