message "Waiting for speed sense" appears on the console.
Since the correct speed for your terminal has not been sensed yet,

text on your console (or simply a few seconds after the Self-test LED
turns off), press [Return] and pause. Repeat if necessary until the router
senses and matches your baud rate. Your console session then begins.
(The detailed procedure for connecting a console is in chapter 1,
"Installation.")
