/*
*
* REVISIONS:
*
*  cad08Sep93: Fix for setting from front end
*  pcy13Sep93: Override SmartUps::HandleLineFail so we dont worry about boost
*  cad16Sep93: Fixed state check bug
*  pcy18Sep93: Cleaned up include files
*  pcy20Sep93: Add line condition to smrt cable event so we dont crash in host
*  cad02Nov93: name fix
*  cad11Nov93: Making sure all timers are cancelled on destruction
*  cad08Jan94: took out get for ups model (virtualized in smartups)
*  pcy08Apr94: Trim size, use static iterators, dead code removal
*  djs22Feb96: Removed smart trim sensor
