Threading generally isn't the way to do networking with Twisted. In fact,
Twisted is almost wholly geared toward avoiding exactly that.

is established. You need to be thinking of your program in terms of events.

You can't really do this. Instead, it seems that since you want to send
a line once the connection is established, you should be putting code into
the event handler for "connection is established". Your example code
already defined behavior for this event, in fact - but you only put a
print statement into it. Try expanding your `connectionMade´ method to
do the other things you want to happen at connection setup time.
