How to Set the Service Line Speed
By default, the service line speed is 1200 baud or 2400 baud depending
on the level of SystemGuard. This speed can be changed through the SystemGuard
MAINTENANCE MENU. In order to use the Service Console properly, the terminal
connected to the S2 connector has to be set to the same speed. This speed is not
necessarily the same as the speed defined in AIX for tty1. To avoid changing the speed of
the terminal itself when AIX is running, it is more convenient to have the same speed for the
Service Console and tty1 defined in AIX.
