Performing a command line flash on the Cisco 600 Series

------------------------------------------------------------------------

Below are basic instructions for performing a command line flash upgrade
on the Cisco 600 series of routers.

            To do this, follow the steps below:

               1. Download newest CBOS flash from
                  http://www.iaxs.net/dsl/support/
                  <http://www.iaxs.net/dsl/support/>
                  Be sure to download correct type (DMT or CAP) for your
                  type of DSL.
                  If you have a Cisco 675 you have CAP. If you have a
                  Cisco 678 it could be either.
                  Call us if you are not sure.

               2. Connect a 9-pin serial port of your PC to the console
                  (MGMT) port of the router with Console/Management
                  cable that came with your Cisco.

                        bps possible)

                      + Data bits: 8

                      + Parity: None
