TFTP was one way.  I transfered the newer CBOS firmware with hyperterminal 
itself using, IIRC, xmodem protocol.

  Get The Firmware

I did this by Googling for "cisco cbos 678", going to the "Qwest | DSL | 
Customer Service" result, clicking the link for Windows users, and downloading 
the file named 678DMTcbos2.4.6.exe.

Upgrade The Modem

     * Extract the firmware with a command-line de-archiver, such as unzip.
     * Install the port comms/ecu.
     * Follow the on-screen prompts to configure the serial port (probably 
/dev/cuaa0) for 38400,8N1.
     * Connect to the router. Log in. Enter "enable mode" by typing en and 
entering your "enable password".
     * Tell the router to enter download mode: type set download code
     * Tell ecu to upload the ROM image: hit <home>sx, enter the filename from 
the "unzip" step above (mine was /tmp/nsrouter.c678dmt.full.2.4.6.bin), and 
watch the upload.
     * DON'T DO ANYTHING! After the transfer is complete, the router will sit 
idle for quite a few tens of seconds. Let it reboot itself (do not powercycle it 
in the meantime!).
     * Do one of two things:
           o Did the unit reflash itself with the updated CBOS version? Pat 
yourself on the back for a job well done!
           o READ THE NEXT SECTION! DO NOT REBOOT YOUR MODEM OR IT WILL BE 
DESTROYED BEYOND REPAIR!
