I am not able to send a break sequence from my HP pro book laptop to Cisco Nexus 9000 series switch over a usb adapter and Cisco console cable.

I tried every possible button combination.

I do not understand who is making the problem? Is it my laptop vendor? Is it Windows 7? Is SecureCRT or Putty? Is it Cisco switch?

I'm surprised <CTRL> + <BREAK> isn't working in SecureCRT. That is the typical key combination for it.

Cisco has a helpful list of break hotkeys for a lot of terminal software. PuTTY isn't in the list, but it has a menu command for sending a break sequence.
