Here you are.. I guess I should just make a webpage for this... there is
also new info on how to do this via serial link, but I didn't write that
part, so it's not in this message.

(Note: I have telnet disabled on my 675 - you could just as easily do the
'serial console' steps over telnet, were you to have that enabled.)

The easy & fast way to upgrade the CBOS (the latest version I found was
2.4.1, so I used it) is via tftp. The drill goes like this: (IMPORTANT
NOTE: I assume that the 675 is ip 10.0.0.1, and the client used to send
the upgrade is 10.0.0.2. Adjust as required for your network.)

Log into CBOS over the serial cable, enter enable mode.

#set tftp enabled
#set tftp remote 10.0.0.2 (this may be optional, but I set it the address
of my desktop. This forces the 675 tftp to only accept tftp connects from
a single host (security)).

Now, from the client machine 10.0.0.2, and assuming you have downloaded
CBOS 2.4.1 as filename 'nsrouter.c675.2.4.1.bin':

$mv nsrouter.c675.2.4.1.bin nsrouter.c675.2.4.1.bin.hr
$tftp 10.0.0.1 69
tftp>mode binary
tftp>put nsrouter.c675.2.4.1.bin.hr
tftp>quit

Back to the CBOS serial console on more time:

#set tftp disabled
#reboot

The modem should reboot, check a bunch of checksums, *then* it flashes the
EEPROM, reboots again and wakes up with the new version. You shouldn't
have to touch any of your NVRAM settings, but if they are ugly, log into
the serial console, enter enable mode and do:

#set nvram erase
#write
#reboot

Then you may configure the unit as if factory-fresh; ppp passwords and
all...
