OK, this is getting very difficult

I have written a comport wrapper class in C#, it works very nice. Now I made the class serializable and a marshalbyrefobject. This because I want it to be remotable.

My idea was/is to make it possible to communicate with my interface card of my home network using remoting. Is this possible with unmanaged code mangled with managed code ? (I used unmanaged code in my comport wrapper class.)

I hope that someone can help me, because I can't get it to work at the moment since my application gives me an remotingException: Cannot create proxy to an unbinded type.
