I want to reset a password on Cisco 3030 switch in a Dell 1955 Bladecenter and I'm capable of restart the switch and connect before it's booting. But when I want to sent ctrl-break using minicom or screen it doesn't pickup it seems and just boots the switch.

I have tried ctrl+a -> ctrl+b on screen and minicom but I get the feeling that the switch doesn't pick it up. Locally this was no issue in the past, or am I doing something wrong ?

Thanks for any suggestions!
