Multithreaded TCP/UDP server

Hi All,

I have a device (GPS module), that's sending a message to specific TCP/UDP port. I'm looking for a server application (preferably not java), that'd be able to handle 50 concurrent TCP/UDP connections at the same time (hence the multithreaded in subj). The GPS device won't let me change the message format (otherwise I could use HTTP servers). I don't want to write the app from scratch - have no experience developing multithreaded apps like this and not enough time either.
I'd like the application to receive the message from the client, store it (this'd be controlled by some handler) and be able to respond as well. It'd be running as daemon, listening on 2 ports (one for UDP and one for TCP).
One option that may work could be tcpcourier...but I'd rather use the tcp server.

Do you know, anyone?

Thanks, Michal
