beeper.disable - Disable the UPS beeper
beeper.enable - Enable the UPS beeper
beeper.toggle - Toggle the UPS beeper
bypass.start - Put the UPS in bypass mode
bypass.stop - Take the UPS out of bypass mode
driver.killpower - Tell the driver daemon to initiate UPS shutdown; should be unlocked with driver.flag.allow_killpower option or variable setting

load.on - Turn on the load immediately
shutdown.return - Turn off the load and return when power is back
shutdown.stayoff - Turn off the load and remain off
shutdown.stop - Stop a shutdown in progress
