How do you send a "Break" on puTTY to a cisco 2600 Terminal server

I have a cisco 2621XM Terminal server connected to A router.  The Terminal server has 32 ports and connected to 32 cisco deviceses. I was trying to login one of my Router which is cisco router 7609 that has a sup-720. The sup-720 failed and I was trying to upgrade the IOS on the sup-720. when I reload it and send a "BREAK" from the puTTY it didn't work.  Is there any way I can send a BREAK from the puTTY or push any key that works.

Thanks.

Hi,

If the standard break sequences do not work, you can try the special commands: right click on the header of putty / Special Commands / Break.

Cheers,

In PuTTY, you can use the key combination of CTRL+Break.

What is the difference

What is the difference between sending a standard break sequence using Control+Break and a special break command using  PuTTY?

The reason for asking is that my colleague could not send a break using the Control+Break keyboard keys but was able to interrupt to booting of an ME3600-X switch using the special break command from the PuTTY menu, which I find rather weird.

use "CTRL + SHIFT + 6 + X"

as far as I know..

and also there is command to enable break on boot.

But, I forgot... try to read IOS command guide.

Not to ressurect a dead thread, but you guys are referencing break sequences for a computer directly connected to a console. All attempts I've tried for these sequences when doing reverse telnet through a terminal server (in my case a 3725) are completely ignored. To my knowledge there's no way to correct this issue.

Yes it's possible. Configure telnet break-on-ip. Then send Interrupt Process signal with Putty Special Command menu.

don't forget to remove the "telnet break-on-ip" command when you're done.

Just as others before, you are not understood the question.

That is, how to send break from a Cisco asynch interface, not how to send break from Putty with serial connection.

Read answer by myself.
