Looking through those docs quickly leads me into quite a bewildering
maze.

As a kind of way to perhaps get me heading in the right direction and
understanding how I start to hang all that together to get what I want,
I would appreciate it if anyone could look at this little code snippet I
have, and illustrate how I can end up doing the same thing with twisted,
but end up with an interactive connection that can handle vi...  From
there I will happily trundle off by myself.

I think I'm looking for help in getting that AhA! moment :)

Snippet;

C=telnetlib.Telnet(self.TCPAddress)
.
.
((connection / password handling etc..))
.
.
if AliasedSubbedCmd=='__interact':
        if system=='UNIX':
        	retkey='^D'
        else:
            retkey='^Z'
	  print '\nTELNET entity '+self.Name+' entering interactive
mode. Use '+retkey+' to come back\n'
	C.mt_interact()


...at this point I am essentially on the remote system command line,
with a very dumb terminal. How could I do this in twisted and end up
with a fairly  clever terminal?


Thanks,

Matt.
