Cannot connect to console after set change speed

When the router starts up, it will be at the new console speed of 57600 bps (0x3122) or 115200 bps (0x3922)

Here is the example if 57600 bps was used:

I use the standard Hyperterminal as follows:
1) Close Hyperterminal
2) Open Hyperterminal
3) Set settings to the following:
speed = 57600
data bits = 8
parity = none
stop bits = 1
flow control = none

When the router boots up, you will see nothing on the screen or just characters. Wait until the router boots up. Then you should be able to access it.

If this fails, here are THREE ways to get the router back:


Option 1:
=========

1) Close Hyperterminal
2) Open Hyperterminal
3) Set settings to the following:
speed = 1200
data bits = 8
parity = none
stop bits = 1
flow control = none

This should give you access and then do the following:

enable
config t
config-register 0x2102

Then reload the router and set your Hypterminal back to 9600 bps.


Option 2:
=========
Connect your console cable to the AUX port on the router at 9600 bps. Then change the config register back to 0x2102 by doing the following: (This will work if you have an enable password set)

enable
config t
config-register 0x2102

Then reload the router.

Option 3:
=========

1) Close Hyperterminal
2) Open Hyperterminal
3) Set settings to the following:
speed = 9600
data bits = 8
parity = none
stop bits = 1
flow control = none

Turn the router off, then on. Press Control-Break. This should put you in ROMMON mode.

Set the config-register to 0x2102 by entering the following command:

o/r 0x2102

Then type i and hit enter to restart the router.

You should now be back to 9600 bps. Set your Hyperterminal back to 9600 bps.
