<p>At times I find myself telnetting from Windows XP to another server and that I state a wrong port number such as</p> <pre><code>c:\&gt; telnet xxxxx.yy pp </code></pre> <p>After hitting Enter, I realize that I entered the wrong port number and would like to abort the telnet process with a ctrl-c, however, telnet doesn't seem to respond even to ctrl-c. So, I have to wait a few seconds until telnet returns with a </p> <pre>Connecting to xxxxx.yy... Could not open connection to the host, on port pp: Connect failed</pre> <p>It's rather annoying to wait for the error message, especially when I already know it will eventually come.</p> <p>So, is there a way to immediately stop the telnet process?</p>

<p><strong>Edit</strong>: Of course, it's never that simple. As you've observed, Microsoft's telnet doesn't respond to <code>^]</code> while waiting for a connection.</p> <p>If you don't want to wait around, you only have two options:</p> <ul> <li><p>Kill the telnet process (from another command shell or the task manager), or</p></li> <li><p>Use another telnet client. <a href="http://www.chiark.greenend.org.uk/~sgtatham/putty/" rel="nofollow">PuTTY</a> is a good choice, since it will launch as a separate window; even if you get the port wrong and the PuTTY window freezes, your command shell will be available to launch another instance with the correct port number.</p></li> </ul> <p><hr></p> <p>Use the escape character (defaults to <code>Ctrl+]</code>). This brings up a telnet prompt at which you can close or quit the connection.</p> <pre><code>&gt; telnet Welcome to Microsoft Telnet Client Escape Character is 'CTRL+]' Microsoft Telnet&gt; </code></pre> <p>You can change this to nearly anything you like on your commandline by using the <code>-e</code> flag:</p> <pre><code>C:\&gt;telnet /? telnet [-a][-e escape char][-f log file][-l user][-t term][host [port]] [...] -e Escape character to enter telnet client prompt. [...] C:\&gt;telnet -e ' Welcome to Microsoft Telnet Client Escape Character is ''' Microsoft Telnet&gt; </code></pre>
