Many times I've had to backup from a serial connection for many different reasons. Test labs, upgrades, etc. Hyperterminal is great for this. Most Cisco device consoles can be connected to with these settings: 9600 baud, 8 data bits, no parity, 1 stopbit, flow control none.
Once connected I'll set the terminal screen length to 0 so that it doesn't prompt me page by page. Do this with the "term len 0" command. Next type in the show run" command, but, don't press enter yet...
If you didn't already love HyperTerminal, you do now, right? Hope this helps.
