Shut down the system using
the System Shutdown Manager or the
shutdown(ADM)
command.
Install the serial card(s) and
configure your hardware according to the
manufacturer's instructions.
If your system includes a configuration disk or
BIOS setup program, use it as instructed. If your
system is configured with switch settings on the main
system board (motherboard), define the new ports by setting
the proper switches (refer to your hardware manuals for
the settings).
Reboot the system, and log in as root.
The next step is to define the configuration of the
serial card hardware using the
Serial Manager.
