I type this command in a Windows Command Prompt in XP.

telnet 80 

Connecting to appears and then telnet window opens, but there is nothing inside it.

If I type any command like GET / HTTP/1.1, it doesn't appear either.

Are my starting steps correct?

i think everything is working as it should - telnet does not echo it's prompt .. just make sure to use the proper commands and encoding ... sending some useless glibberish should prompt some answer though. – CKoenig Aug 17 '11 at 16:18
I m sorry, but what does that mean ?? – ShantanuD Aug 17 '11 at 16:18
type "telnet 80", enter, type "GET/HTTP/1.0" (won't show on screen), Then press enter twice. (Don't type quotes) Don't bother though, it's just an error. – user175737 Nov 25 '12 at 4:27

Telnet has no echoing by default. Enter telnet in interactive mode (no arguments, just execute telnet). Then type set localecho. Then open host port.

I suggest you to use netcat, easier to use and way more powerful. telnet is obsolete.

You're trying to connect to an HTTP server, that's what is on port 80 most of the time. The HTTP protocol requires that the guest start talking first. You may want to read up on HTTP if you want to explore:

But connecting to port 80 won't get you a shell, telnet servers usually operate on port 23. But telnet is not really used over the Internet anymore because it's not secure.
