After running "accept", check the openSockets.  You should see one which 
has no IP address, and is just the port number you're listening on, e.g.:

   accept connections on port 4444 with message "foo"
   put the openSockets

..should yield:

4444

If you then close that you should be unable to receive further connections:

    close socket 4444
