Are you interested in backing up the IOS or the start-up-config?

You can not use the console port

If you want to back up the IOS, then you need to configure a laptop or a PC as a TFTP server and then connect the router to the PC and on the router you issue the command:

copy flash tftp (the ip address of the PC)

Have a look at thes documents for more info:

Console port is meant for management and I dont think data traffic is possible. So you may not be able to backup the IOS via console port. You need reachability to TFTP or FTP server to backup your IOS.

via console its not possible try a tftp or a ftp server if you have.

Boot up in rommon and perform an X-Modem transfer.  WIll take you a few hours.  Use HyperTerminal Receive File Xmodem.

This was availble on older 2600/3600 routers and it 'could' be availble on the 7600s.....

other option is to follow along what everyone else said --- setup a temp vlan or interface and tftp/ftp it from your netbook.
