How to do Crtl+Break sequence in SecureCRT without a Break Key

So, for the past couple years I've been using a Mac Book Pro for the majority of my writing, but still relied on a Windows platform for most of my command line work. I recently was faced with the need to perform a password reset on a device using Secure CRT on my Macbook Pro, and wouldn't you know it? There's no Break key! Here's how I got around this issue, if you have another way to do it, please feel free to share in the comments below.
1. Start out by establishing your console connection.
2. In Secure CRT, Click on the Options button (or go to the Options menu and click Session Options).
3. Click on Mapped Keys under the Emulation Section.
4. Click on the Map a Key button, then type whatever key combination you want when it prompts you (I typed Ctrl+delete).
5. In the Function drop down, select Telnet Function.
6. In the Telnet Function drop down, select TN_BREAK.
7. Click Ok.
You should now be equipped to issue a break sequence when consoled into a device. Go forth, and use your new found powers for good.

Thanks! I will try right away. This was one of two issues that I had with Macbook Pro-everything else is great.
So how about this one: tftp server for backing up the iOS? I know there is a GUI application out there, but I couldn't get that to to work. I also know there is a built in tftp, but same thing!
There is an awesome tftp
There is an awesome tftp server for Macs. Here's a blog post on how to get it installed.

Thanks!
I have been wondering about FTP backup on my new Mac, made the switch from PC last month and couldn't figure it out. Keep the Mac advice coming!
ctrl-break combo in *any* terminal software ;)
This is how I do this:
1) select speed for COM the lowest possible (300bps, 150bps...)
2) establish connection through COM port
3) start pushing SPACE key during booting your device
4) after getting to rommon don't forget to change back your speed to 9600bps (or speed you've chosen before your 'breaking' to router).
it's related with character code of SPACE key - when you push it - from electrical point of view you generate high signal level. Which is treated as a 'electrical break' by your device.
I've done this many times with many cisco devices and many terminal software (even MS HyperTerminal). you need just to remember to reverse speed change. And sometimes you need to push SPACE key several times.

Thank you!
I remembered reading this on your blog a while back and I just needed to do a password recovery on a router, but I couldn't remember how to do this. Did a quick search on your site and found this post. Totally awesome! Thanks!
