Extracting data from telnet session ?

[Henning Sauer]

Hello,

I want to extract status information from a router to which I can
connect via telnet. 
Currently I try the following:

import getpass
import sys
import telnetlib

HOST = "192.168.0.1"
password = getpass.getpass()

tn = telnetlib.Telnet(HOST)
tn.set_debuglevel(1)
tn.read_until("Password:")
tn.write(password+"\n")

tn.write("24\n")
tn.write("1\n")
print tn.read_all()

this gets me output like this:
 
Telnet(192.168.0.1,23): recv '7;1H'
Telnet(192.168.0.1,23): recv '\033[8;1H'
Telnet(192.168.0.1,23): recv '\033[8;26H8\033[8;38H76\033[8;53H24542\033[8;65H696\033[8;79H2\033[8'
Telnet(192.168.0.1,23): recv ';1H'

Telnet(192.168.0.1,23): recv '[8;1H'
Telnet(192.168.0.1,23): recv '\033[11;1H'

Telnet(192.168.0.1,23): recv '\033[4;62H'
Telnet(192.168.0.1,23): recv '\033[21;49H'

What I would like to know is how can I extract the information 
from this data stream ? 
Is this really the data from the router or might it be debug 
information ? When I'm not setting the set_debuglevel I'm 
getting no output.
 
Bye,
