problems with telnetlib

[Andre van Straaten]

As no one has responded so far, my hint is to have a look for the
specification of the terminal you send to the server.

The following three lines are a simple script which sets up as default a
very dumb terminal which cannot even filename completion, but you insert
characters (after naturally having logged in).

import telnetlib
se = telnetlib.Telnet("209.150.158.130")
se.interact()

Try this to exclude other sources of errors, and then search for terminal
set up (and maybe the prompt, too).
