...cause I need some help to connect my app to a custom server!

How does it work?
How do I say to the server that he should listen to the IrDa Port?

Thanx.

bye

What are you actually trying to do here? Are you trying to receive files/messages over IrDA? Some more context would be helpful.

Yeah...for example.

I mean, how do I use custom servers generally? I know that I need some kind of a protocol...

How do I connect? How do I implement it in my code? What kind of classes do I need...a.s.o.

I'm new in that.
