Closing telnet connection gracefully from session mode itself without going to telnet prompt

a normal telnet connection is like this:

telnet localhost 22
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
SSH-2.0-OpenSSH_4.2
^]
telnet> close
Connection closed.

I want to close it from telnet session itself without coming to telnet prompt by pressing.
My requirement is that if i press some control character from telnet session itself like CTRL+A so it will come out of session and close it automatically.
something like this:

$ telnet localhost 22
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
SSH-2.0-OpenSSH_4.2
^A
Connection closed.
$

I tried all the options given at the man page and tried to do some $HOME/.telnetrc file tests but couldn't achieve it, as telnetrc will execute all the commands written in it with the given host whenever a telnet to that host is done.

Can anyone help me in this, like how it can be achieved.
