When I do:
1)Write this code: in Dr. Racket:
#lang racket
(define server (tcp-listen 12345))
(define-values (s-in s-out) (tcp-accept server))
2)Ctrl+R
- DrRacket waits(lock the REPL) for connections
3)Write this code in python:
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('localhost', 12345))
- DrRacket unlock the REPL
4)s.send("hello") #in Python
5)(read-line s-in) ;in Racket
- Racket doesn't read "hello", it locks the REPL.
Help me please...
best regards,
Alejandro

This should just work.
Can you show what code you're doing?
For example, given the following echo-server written in Racket,
;;;;;;;;;;;;;;;;;;;;
#lang racket
(define listener (tcp-listen 12345))
(let echo-server ()
(define-values (in out) (tcp-accept listener))
(thread (λ () (copy-port in out) (close-output-port out)))
(echo-server))
;;;;;;;;;;;;;;;;;;;;
then the following interaction in Python shows that this is doing
something:
###########################################
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('localhost', 12345))
s.send("hello")
5
s.recv(500)
'hello'
###########################################
