+a simple experiment on communication via tcp ports
+
+a server runs continously servicing clients. Clients connect, send a message, and
+server replies with a message. Message should appear in each separate REPL area
+prompt
+
+run server.rkt in a REPL
+```
+,en server.rkt 
+(define stop (serve 8080))  ;; starts serve listening at port 8080
+(stop) ;; to stop server and free the ports
