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.
