[Twisted-Python] twisted, nc and LineReceiver

Hello, it's me again ;o) So there's this server I'm porting from a ForkingTCPServer to twisted. It listens on a socket, and reads one line at a time, processes the line and writes the answer back on the socket to the client. The ForkingTCPServer version uses a handler deriving from StreamRequestHandler, and gets the data with self.rfile.readline(). The twisted version uses a LineReceiver protocol. Now, if I use telnet to connect to both version of the server, I can type some data, press return and get the answer back. This is great. However, if I use nc send the data, the twisted-based server sees nothing (lineReceived is not called!) I have to admit I'm baffled, and I'll take any idea. -- Alexandre
