HELP Applescript for telnet

[SOOMINAHN]

Hello everyone.

I would like to know correct script for telnet connection.
Below script is one I made. But it is not working.
Especially I don't know what I should use keyword or command on red part.

launch "iTerm"
tell application "iTerm"
	activate
	set myterm to (make new terminal)
	tell myterm
		launch session "Default Session"
		tell the last session
			write text "telnet 192.168.2.3 2001"
			write text "enable"
			write text "password"
			write text "reload"
			if output = "System configuration has been modified. Save? [yes/no]:" then
				write text "n"
			else if output = "Proceed with reload? [confirm]" then
				write text "y"
			end if
		end tell
	end tell
end tell

Please teach me how solve this problem.
Thank you for your attention.
