Network UPS Tools (NUT) is a client/server monitoring system that\\ allows computers to share uninterruptible power supply (UPS) and\\ power distribution unit (PDU) hardware. Clients access the hardware\\ through the server, and are notified whenever the power status\\ changes. \\ upsrw allows you to view and change the read/write variables inside your\\ UPS. It sends commands via the upsd to your driver, which configures the\\ hardware for you. The list of variables that allow you to change their\\ values is based on the capabilities of your UPS equipment. Not all\\ models support this feature. Typically, cheaper hardware does not\\ support any of them.\\ \\
