About Communicating With the System
To install your system software or to diagnose problems, you need some way to
interact at a low level with the system. The system console is Sun's facility for doing
this. You use the system console to view messages and issue commands. There can
be only one system console per computer.
The serial management port (SERIAL MGT) is the default port for accessing the
system console upon initial system installation. After installation, you can configure
the system console to accept input from and send output to different devices. See
