This document describes the command/response protocol currently used
in the management of Uninterruptible Power Supply (UPS) units and
other power devices often deployed in small offices and in IT
installations subject to an erratic public power supply.  The UPS
units typically interface to an Attachment Daemon in the system they
protect.  This daemon is in turn polled by a Management Daemon that
notifies users and system administrators of power supply incidents
and automates system shutdown decisions.  The commands and responses
described by this document are exchanged between the UPS Attachment
Daemon and the Management Daemon.  The practice current when this
protocol was first developed risks weak security, and this is
addressed in the Security Considerations sections of this document.
