Using twisted,

[Matthew Warren]

I'd suggest taking a look at Twisted, which contains a more complete
telnet implementation (not as important for being able to launch vi),
an ssh implementation (which you might want to use instead of telnet),
a VT102 implementation (which is actually what will help you
run programs
that want to fiddle around with the cursor in fancy ways), as
well as a
fair amount of work towards a simple terminal emulator (to
help you keep
track of what vi has done to your virtual terminal).

API docs for insults:

http://twistedmatrix.com/documents/current/api/twisted.conch.i
nsults.html

And for the telnet implementation:

http://twistedmatrix.com/documents/current/api/twisted.conch.t
elnet.html

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.
