RE: [nsp] Reset password for Cisco 802 router, break not working

This is located from the Password recovery section on Cisco's website
(http://www.cisco.com/warp/public/701/61.html)... It has worked for me in
the past.

How to Simulate a Break Key Sequence
This is useful if your terminal emulator doesn't support the break key, or
if a bug prevents it from sending the correct signal (the hyperterminal
under Windows NT used to suffer from this behavior):

Connect to the router with the following terminal settings:
1200 baud rate
No parity
8 data bits
1 stop bit
No flow control

You no longer see any output on your screen. This is normal.

Power cycle (switch off and then on) the router and press the spacebar for
10-15 seconds. This generates a signal similar to the break sequence.

Disconnect your terminal and reconnect with a 9600 baud rate. You should now
be in ROM Monitor mode.
