 *  pcy11Dec92: include smartups.h instead of backups.h
 *  pcy11Dec92: Initialize theCommController in the constructor
 *  ane16Dec92: Comment out passing of gets/sets to host object, handled in app now
 *  ane05Jan93: Added code to support slaves
 *  ane11Jan93: Register for additional events when a slave
 *  pcy26Jan93: Construct SmartUps/BackUps based on ini file
 *  pcy26Jan93: Return construction errors in theObjectStatus
 *  ane03Feb93: Added state and SetInvalid and state checking
 *  pcy16Feb93: Get rid of SORRY CHARLIE debug msg
 *  tje24Feb93: Added Windows support
 *  jod14May93: Added Matrix changes.
 *  cad10Jun93: Added MeasureUPS support
 *  cad15Jul93: Moved add-ons to under smart comm
 *  cad04Aug93: Fixed up admin shutdown handling
 *  cad27Aug93: Added handler for is measureups attached get
 *  cad14Sep93: Handling measureups non-null, but not really there
 *  cad20Oct93: Better MUPS checking
 *  cad27Oct93: even better than that
 *  jod02Nov93: Added CIBC conditional statements
 *  cad11Nov93: Changed handling of Comm Lost
 *  cad17Nov93: .. more little fixups
 *  rct21Dec93: fixed bug in Get()
 *  pcy08Apr94: Trim size, use static iterators, dead code removal
 *  ajr22Aug94: Lets not auto-detect mups because of ShareUps problems.
 *  ajr14Feb96: Sinix merge
 *  cgm29Feb96: Delete the created UPS if lost comm in first 3-10 sec
 *  djs22Feb96: Changed to new firmware rev interface
 *  cgm29Feb96: (NetWare) Override switch
 *  cgm17Apr96: Delete the ups before commcontroller
 *  cgm17Apr96: Don't create measureups without valid ups object
 *  djs17May96: Added DarkStar device
 *  srt02Apr97: Added fix for potential bug
 *  tjg02Dec97: Changed darkstar to symmetra
 *  tjg26Jan98: Added Stop method
 *  clk13May98: When getting value for IS_SYMMETRA, always get value from UPS
 *  mholly12May1999:  special handling of TURN_OFF_SMART_MODE code
 *
 *  v-stebe  29Jul2000   Fixed PREfix error (bug #112614)
