/*
*
* NOTES:
*
* REVISIONS:
* rct11Dec92 compiled w/o the TurnOffUpsOnBatterySensor
* SjA15Dec92 Fixed macro problems and now registers for events.
* jod16Dec92: Moved cdefine.h to top of file.
* pcy27Dec92: Parent is now an UpdateObj, not a DeviceController
* pcy27Dec92: Sensors no longer initialized explicitly. Done during construct
* ane11Jan93: Added generation of a RUN_TIME_EXPIRED event
* pcy02Feb93: Scoped declaration of run_time_remaining so compilers dont error
* ane03Feb93: Added destructors, commented out one of the timers being set
* pcy1&Feb93: Set value to RUN_TIME_EXPIRED for RUN_TIME_EXPIRED event
* ajr22Feb93: moved process.h into C_OS2 cond
* cad04Aug93: Changed shutdown handling for status
* cad14Sep93: looking at shutdown_status to set shutdown flag
* pcy20Sep93: Reset theRunTimeRemaining when setting line good
* cad27Sep93: Added enabling battery run time
* cad02Nov93: name fix
* cad15Nov93: Changed how comm lost handled
* cad10Dec93: firmware rev get added
* pcy28Jan94: Handle run time timer different (now in Shutdowner)
* ajr08Feb94: Fixed TIMED_RUN_TIME_REMAINING case
* cad08Jan94: removed run time enabled stuff (assumed by flex shutdown)
* pcy04Mar94: Make sure ups gets shutdown events
* pcy08Apr94: Trim size, use static iterators, dead code removal
* rct03Jun94: Added functionality for tracking xfer cause and time on battery
* jps20jul94: itoa -> ltoa (theUpsState); added some (time_t *)s
* ajr02Aug94: Lets set the line to bad if we are in bad bat state
* ajr02Aug94: moved BACKUPS_FIRMWARE_REV definition to backups.h
* ajr14Feb96: SINIX Merge
* djs16Jul96: Added IS_BACKUPS
* mds29Dec97: Enabled the TurnOffUpsOnBatterySensor to correctly shutdown
* UPS when using a Share-Ups in confirmed mode.
* tjg12Jan98: Undid the changes to TurnOffUpsOnBatterySensor
* clk09Sep98: Reworked LineBad condition in HandleBadBatteryCond to always
* setBatteryBad (fixes SIR 6019).
