UPS Monitor Program via serial interface
UPSD is a daemon to monitor an Uninterruptible Power
Supply (UPS) connected to a Linux computer's serial
port. It will signal init(8) when the UPS is operating
on battery power so that the computer can be shut
down cleanly. UPSD has additional features, including
network monitoring, low battery warning, and the
capability of turning off the UPS during the shutdown
process (if the UPS supports this). In addition it has the
capability on slave systems of monitoring the remote
master for the return of power in the event that only the
master power has failed. A debugging and management
tool is included. Support added for socks firewalls,
May 2000.
