7F. Changing the Fortress’ Baud Rate
As shipped, your Fortress is set to communicate at a baud rate of 1200. If you want to
use two-way communication, but your computer or terminal cannot communicate with
the Fortress, make sure the computer or terminal is also set to 1200 baud. If you want to
change the Fortress’ baud rate, you must establish two-way communication with the
Fortress; for instructions,
