echo-client-server-rkt

A simple echo client and server in Racket that I created in order to learn TCP socket programming in Racket.

To start the server, open the echo-server.rkt file in Emacs Geiser, then enter the module and issue the following command in Geiser's REPL:

(define stop (echo-server 8080))

replace 8080 with your desired port.

To shutdown the server, invoke the stop function.

(stop)

In order to start the client, issue the following command from the terminal:

$ racket echo-client.rkt 8080

again, replace 8080 with the port that your server use.

To shutdown the client, just type exit and press enter.

For some reason, the read-line and read-bytes-line functions do not block and wait for user input when invoke in Geiser's REPL.
