   4 # Enters via the avr_evtd daemon with the following command options:
   5 #  0 - Special event following double press of the 'red' reset button
   6 #  1 - AVR device has requested a halt due to error
   7 #  2 - Shutdown request from timed shutdown logic

   9 #  4 - User has pressed the power button
  10 #  5 - User has released the 'red' reset button
  11 #  6 - User has pressed the reset button
  12 #  7 - User has held the power button > 3 seconds
  13 #  8 - User has held the reset button > 3 seconds
  14 #  9 - Disk used beyond DISKCHECK%
  15 #  F - Fan failure event, fan stopped for > FANSTOP seconds
  16 #  E - User selected EM-Mode
  17 #  S - Five minute shutdown warning event
  18 #  D - Error message handler
