ComfoAir OpenHAB3 Binding over Moxa NPort5100


I have an OpenHAB3 installed on a Raspberry4 and want to replace an older Wiregate with it in the long run.
On the Wiregate runs a script to control my Zehnder ComfoAir350 which is connected to the network via a Moxa Nport5100. The Wiregate communicates via a UDP port with the NPort.
Do I understand correctly that OpenHAB3 binding only allows COM ports?
I have tried to compile and install a Moxa Real COM driver with various instructions but this is too much for my Linux knowledge.
Is there a way to install the driver via UDP? or a simple guide/script?
Thanks for the answers
