I am trying to make a flex application where it gets data from a telnet connection and I am running into a weird problem.

To give a brief introduction, i want to read data from a process that exposes it through a socket. So if in the shell i type telnet localhost 8651i receive the xml and then the connection is closed (I get the following Connection closed by foreign host.)

Anyway i found a simple tutorial online for flex that essentially is a telnet client and one would expect it to work but everything follows Murphy's laws and nothing ever works!

Now i have messages being printed in every event handler and all places that i can think off. When i connect to the socket nothing happens, no event handler is triggered even the connect or close handler and if i do the following the socket.connected returns false! I get no errors, try catch raises no exception. I am at a loss as to whats going wrong?

        socket.connect(serverURL, portNumber);
        msg(socket.connected.toString());

Is there something about telnet that i do not know and its causing this to not work. Whats more interesting is why none of the events get fired.

Another interesting thing is that i have some python code that does the same thing and its able to get the xml back!

The following is the python code that works!

  def getStats(host, port):
 sock = socket.socket()
 sock.connect((host, port))
 res = sock.recv(1024*1024*1024, socket.MSG_WAITALL)
 sock.close()
 return statFunc(res)

So i ask you whats going wrong!!!!!! Is there some inherent problem with how flex handles sockets?
