Disconnecting a telnet session

How can I disconnect an existing telnet session? The host is a serial port server with multiple ports. The users login using the host's name and a port, i.e. telnet host01 1235.

Thanks.

Yep "Control-]" will take you to a "telnet>" prompt, at which you can type the quit command "q".

For some reason, my previous posts are not showing up on this thread. I tried three times.

That's not what I'm looking for. That only works if I'm have the terminal with the telnet session in front of me. Specifically, I want to use write a script that disconnects an existing telnet session. The telnet sessions do not require user names and passwords; anyone can login by telneting into a host and port number. I do not know from what host the user may be logging from. For example, a user may working be on machine M may log into host H on port P by entering "telnet H P". I may be on machine M2, but I won't know where the other host is logged from, but I do know what host and port the user is logged into because I can't connect to the host-port
I've tried using pexpect to try sending some escape characters into a telnet stream, but I can't even login to the host-port because someone else is already on it.

You mean you want till kill somebody elses telnet session when

(a) you can't actually log into the server; and

(b) you can't log into the client machine the user is telnet'ing from?

You can find their shell process using the "ps" command an kill it.
You need to be root to kill another person's process.
