bps. But if you
send a Break signal (by pressing the
BREAK
key), the port speed will change to the next
higher speed. When it reaches the highest speed (
38400
bps), it toggles back to the lowest
speed (
1200
bps). You cycle through the port speeds in the following order:
9600
–

you must remove the default baud rate
shunt (

), which fixes the baud rate at 9600 bps,
before you can change the baud rate. This shunt is
located near the front end of the circuit board, just to
the right of the Ethernet management port.
