That is a nice way to detect disconnection, but I think the question
was, how to receive messages from the other side? In console mode you
can simply do a while loop with recv() in it and check what comes
back. This is not so straightforward in Tk, you are either in
mainloop or in your own loop, and unless there's some special event
in Tk which can be called periodically, I don't know how to do this
