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
run client.rkt in a separate REPL
,en client.rkt
(define stop (client 8080)) ;; starts client talking to server at port 8080
