scripting telnet using 'expect'
Simplest I've found yet has been an expect script...
It exists on most unix machines in standard load, if not you may have to compile it...
In simplest terms, it does exactly what the name says, You type a command , you type what you "expect", it responds by continuing to the next line. Find a simple example below:

#! /usr/local/bin/expect -f
spawn tn rst41880
expect "login:"
send "{USER}\r"
expect "Password:"
send "{USER_PASSWORD}\r"
send "export DISPLAY={YOUR_HOSTNAME}:0\r"
send "{SUBSEQUENT_COMMANDS}\r"
interact
