Set DSR pin (serial) on startup

Setup, Configuration and Use Scripts & Rules
,
1

I have a RS232 module that sends a string when the connected buttons are pushed.
But depending on the state of the dsr pin it send that data to one of the two RS232 connections.
Use:
without DSR enabled it sends immediate to the relay card without more functionality.
with DSR enabled it goes now to my rs232 of a regular pc with a .net program.
But I want to leave the pc with .net and go to openhab.

I know there is a serial binding and that it is possible to run a rule when the system starts up.
(Not sure witch level I need)
But is it possible to enable the DSR pin in such a rule/script?

Anyone an idea?
Thanks
Pieter

I once learned that @Kai made a serial button binding: Serial Button - Bindings | openHAB, not sure if it solves in any way your rs232 issue, but it might show you a fairly basic code which you could try to adopt in your deployment.

Ok not possible then.
Then I have to search for an other appoach.
Pitty I hoped like by home assistant it was possible.
