Re: Password Recovery

Have you check the PC manual for Break key.

Cisco CCO also have a page with the many different break keys for different PCs and OS.

Re: Password Recovery

Thanks Gilson for your answer, but I tried all the different break keys in accordance with instructions on Cisco's page. I read the winnt's help, but I didn't find the solution. Yesterday I could by Windows 2K, I used break combination.

I don't know why with winnt it hasn't been workink.

Re: Password Recovery

Hello Paulo,

Just in case you get stuck again with this problem in the future and you don't have any other choice but to use the NT 4.0 machine, then this is what you need to do.

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.
