Problem in connecting nodes of Cisco Terminal Server

[abhijitbakale]

I have several devices connected to cisco Terminal Server and while I am trying to reach out to those nodes, I am not about to get in.

The code:
from Exscript.util.interact import read_login
from Exscript.protocols import Telnet

account = read_login()
conn = Telnet(debug=5)
conn.set_driver('ios')
conn.connect('192.100.101.201', 2042)
conn.login(account)
conn.execute('conf t')
conn.send('exit\n')
conn.close()

Output Traceback Stack:

You'll have to implement your own driver. The ios driver in this package doesn't handle ANSI escape codes.
(posting this in case someone comes across a similar issue in the future).
