Firmware Flash from CAP to DMT on Cisco 678

Can I use Hyper terminal to communicate via the serial management cable to a Cisco 678 which is currently configured as a CAP modem with latest cbos 2.4.6?

Please tell if any or all of the following 3 possibilities will work:

A. Use hypertrminal and a serial conneciton to"set download code" using the transfer in function in hyperterminal.

B. using tftp, which seems more confusing, or

C. use the boot-up crtl-C to get in and do the routine I found on xmission general apparently from

- but with the DMT code of course. : es 0 --erase sector 0 es 1 --erase sector 1 es 2 --erase sector 2 es 3 --erase sector 3 es 4 --erase sector 4 es 5 --erase sector 5 es 6 --erase sector 6 (running config) --note this will require the router be reconfigured

df 10008000 --download the file to this location in memory --start and xmodem download with the 675 image --after transfer is complete you will see the # of bytes it --has written - e.g. 00fe8001 - you will need this later

pb 10008000 fee00000 --program the area of memory to flash area -- is the # of bytes (no brackets) the --monitor reported being downloaded

m0 --turn off monitor rb --reboot
