>Change the console baud rate. In order to make this operation safer,
there will be a slight pause after the
first message to give you time to change to the new baud rate.
If it doesn't work, or a less than affirmative answer is given to the
"continue" prompt, then the baud rate will revert to the current value.
Only after the baud rate has been firmly established will <SPAN
