When you open a telnet session in a script you must read the session prompts and write the replies. For example, you open a telnet session in a script and read the session and when you match the word 'Login' (or whatever) you write the user id. The same for password.
In other words, you automate in the script what you manually do at the keyboard. When you do it from the keyboard, you telnet, then wait for the login prompt. When you get the login prompt, you type the login. etc.
Writing a script is the same for telnet sessions, however instead of the keyboard, you echo (or write) in the script. Instead of seeing the login problem, you match the pattern in the script (your eyes, so to speak).

Hi Guys,
How do I write the script for the following
telnet 192.168.1.100 9002
if the result is less than 1 second. The script should say as port open
if the result takes more than 3 seconds. The script should display as port closed.
Thanks,

KF(1) BSD General Commands Manual KF(1)
NAME
kf -- securely forward tickets
SYNOPSIS
kf [-p port | --port=port] [-l login | --login=login] [-c ccache | --ccache=ccache] [-F | --forwardable] [-G | --no-forwardable]
[-h | --help] [--version] host ...
DESCRIPTION
The kf program forwards tickets to a remote host through an authenticated and encrypted stream. Options supported are:
-p port, --port=port
port to connect to
-l login, --login=login
remote login name
-c ccache, --ccache=ccache
remote cred cache
-F, --forwardable
forward forwardable credentials
-G, --no-forwardable
do not forward forwardable credentials
-h, --help
--version
kf is useful when you do not want to enter your password on a remote host but want to have your tickets one for example AFS.
In order for kf to work you will need to acquire your initial ticket with forwardable flag, i.e. kinit --forwardable.
telnet is able to forward tickets by itself.
