You have to first get an incoming connection on your listen port.
Once you get your TCP connection, then you can start reading/writing
messages from/to it.
I have written some sample code on how to do this at:
http://www.rebol.org/advanced/multisession.html
REBOL version at:
http://www.rebol.org/advanced/multisession.r
This may be more than what you what to do (it handles multiple
connections concurrently) but it is easy to modify for your use.
