can you ping the 675? The 675 defaults to a 10.0.0.1 ip addres

able to telnet to it.
You should be able to connect with Hyperterminal.....
I have run across several a 675 that has Telnet disabled
until you set an exec password.
set hyperterm to run at 3840 8 N 1 No flow control...
If you find that your Cbos has been corrupted you need to reinstall it.
The following is taken from Cisco on how to do this. Be warned if you screw
this up... Well you know.
BTW, if you need the CBOS 2.2 firmware let me know and I'll send it to you.

Process 3 - Upgrading your existing Cisco 675 External Modem operating
system to version 2.2:
Ensure that your PC, Ethernet Card and Cisco 675 External Modem are
connected, configured and operational. This should be apparent if you're
currently using MegaBit Services.
Ensure that the serial cable is installed between the PCs COM Port
(DB-9) and the Cisco 675s MGMT Port (RJ-45). If you are unsure,
please consult your MegaBit Services User Guide. The serial cable
facilitates upgrading the Cisco 675 External Modem operating system.
Note to which PC COM Port that the serial cable is installed. You will
need
this information for the next step.
Configure HyperTerminal
The following step assumes that you have not created a session icon for
HyperTerminal and the Cisco 675 External Modem.
Navigate to the HyperTerminal application.
If you are a Windows® 98 user, you may have to install HyperTerminal from
your
Windows® 98 compact disc. If Hyperterminal is not working properly, for
example, if you are receiving an "illegal operation" message, please go to
the
following website and upgrade your existing Hyperterminal application:
http://www.hilgraeve.com/
Select and name an icon for the Cisco 675 External Modem.
In the "Connect using" box select the appropriate COM Port that the
serial
cable is installed.
In the "Properties" window, ensure these port settings:
Bits per second: 38400
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Click OK and press [Enter].
A HyperTerminal Session window appears with a welcome message and
a password prompt.
Hello!

Password:
If you don't see this information, press [ENTER] a few times.
If you still don't see the welcome message, verify connections and power
to your modem.
If you just see "cbos>", that is OK.
You don't need a password to configure the modem.
At the password prompt press [ENTER].
Updating the Modem Operating System
The following step requires your modem to be in the "enable" mode. This mode
allows changes in configuration.
At the cbos> prompt, type: enable and press [ENTER].
At the password prompt press [ENTER].
The enable mode ships default from Cisco System without an enable mode
password. If you have previously programmed an enable mode password,
enter that password now.
The following should be displayed:
cbos>enable
Password:
cbos#
The pound sign indicates that you are in the enable mode.
Before continuing with the following steps, please read the next few lines
of
directions up to the WARNING message below.
At the cbos# prompt, type: set download code then press [ENTER].
The following should be displayed:
cbos#set download code

You will be selecting the file that you downloaded into a new folder.
Select your hard drive and locate the folder and file that you created
earlier.
Select the file nsrouter.c675.2.2.0.000.ima.
In the Send File Window, Protocol field, ensure that Xmodem is
selected.
In the Send File Window, select the Send button.
WARNING! It is extremely important that power is not interrupted to your
equipment!
