[Twisted-Python] struggling with twisted telnet

[Andrew Roden]

The answer is no I wasn't running it with twistd as I didn't need to with
the ssh one... having now run it with twistd I can see the exceptions it
throws but I have absolutely no clue how to go about rectifying them :(
>From what I can make out the main issue is with no terminal size being set
which from the demo_insults.tac looks like it's set in my class that deals
with connections associating it with insults.TerminalProtocol (eg. class
DemoProtocol(insults.TerminalProtocol): ) however, I am dealing with my
connections in recvline as I don't want it to react on a per character basis
but rather a per line basis...

*confused of england*
