bkpupsd - Back-UPS Pro. UPS daemon ---------------------------------- This is a simple uninterruptible power source (UPS) daemon which supports APC Back-UPS Pro(TM) series. The UPSd works as UPS driver, sensing line-failures, shutting down the system cleanly, and finally shutting down the UPS itself. This UPSd provides only the "dumb mode", and the advanced features are not supported.
