This man page only documents the hardware-specific features of the safenet driver. For information about the core driver, see nutupsdrv(8).
This driver supports UPS equipment which can be controlled via SafeNet v1.0 for Windows (serial interface only).
This driver supports the following optional settings in the ups.conf(5) file:
This driver supports some instant commands (see upscmd(8)):
If you run the shutdown.return command with mains present, the output may stay on or switch off and not back on again. The shutdown.reboot command will unconditionally switch on the load again (with or without mains present).
If the driver is called with the -k option (or through upsdrvctl shutdown) it tries to detect which command should be used in an attempt to stay off until mains is present again or to cycle the output if the power returned in the mean time. This isn't bullet-proof, and you should be prepared that the power will either not be shutdown, or that it doesn't return when the power comes back.
