"merge" file descriptors?

To simplify things, I am trying to use tcpserver to create a ... tcp server...Smilie
tcpserver loops for connection attempts, accepts it, then runs a designated program with stdin and stdout linked to the sockets it created.

I'm trying to use this with a program that was written to use a single read/write file descriptor, notably a /dev/. How can I use both stdin and stdout as a single read/write file descriptor?
