RedHat 9 (Linux i386) - man page for nutupsdrv (redhat section 8)

NUTUPSDRV(8)			     Network UPS Tools (NUT)			     NUTUPSDRV(8)

NAME
       nutupsdrv - generic manual for unified NUT drivers

SYNOPSIS
       nutupsdrv -h
       nutupsdrv [-a id] [-d num] [-x var=val] -k device
       nutupsdrv [-a id] [-x var=val] device

DESCRIPTION
       nutupsdrv  is not actually a driver.  This is a combined man page for the shared code that
       is the core of many drivers within the Network UPS Tools package.

       For information on the specific drivers, see their individual man pages.

       In general, all UPS drivers provide a communication channel between the	UPS  attached  on
       device  and  the upsd daemon. The driver's task is to pass to the upsd process information
       about the UPS state and parameters.

       The core has two modes of operation which are determined by the command line switches.  In
       the  normal  mode, the driver will periodically poll the UPS for its state and parameters.
       The results of this command is presented to upsd.  The driver  will  also  handle  setting
       variables and instant commands if available.

       The  driver  can  also  instruct the UPS to shut down the load, possibly after some delay.
       This mode of operation is intended for cases when it is known that the UPS is running  out
       of  battery  power  and	the systems attached must be turned off to ensure a proper reboot
       when power returns.

NOTE
       You probably don't want to use any of these options directly.  You should use upsdrvctl(8)
       to  control  your  drivers,  and  ups.conf(5)  to configure them.  The rest of this manual
       describes options and parameters that generally are not needed by normal users.

OPTIONS
       -h     display an help message without doing anything else.  This will also list  possible
	      values for -x in that driver, and other help text that the driver's author may have
	      provided.

       -a id  autoconfigure this driver using the id section of ups.conf(5).

       -d num wait additional num seconds after receiving the shutdown command in  shutdown  mode
	      before  turning  off  power  to  the  load.   Also  configurable	via  "sddelay" in
	      ups.conf(5).

       -k     ("kill" power) Force shutdown mode.  The UPS will power off the  attached  load  if
	      possible.

	      You  should  use	upsdrvctl  shutdown  whenever  possible  instead  of calling this
	      directly.

       -x var=val
	      define a variable called var with the value of var in the driver.  This varies from
	      driver to driver - see the specific man pages for more information.

	      This is like setting var=val in the ups.conf(5), but -x overrides any settings from
	      that file.

       device The /dev entry corresponding to the TTY the UPS is connected to.	This is  optional
	      if  you  are  using  the -a autoconfiguration option, since the "port" entry in the
	      ups.conf(5) will be used when available.

DIAGNOSTICS
       Information about the startup process is printed to  stdout.   Additional  messages  after
       that  point  are  available in the syslog.  The ups clients such as upsc(8) can be used to
       query the status of a UPS.

PROGRAM CONTROL
       You should always use upsdrvctl(8) to control the drivers.  While drivers can  be  started
       by hand for testing purposes, it is not recommended for production use.

FILES
       ups.conf(5)
	      Required	configuration  file.  This contains all details on which drivers to start
	      and where the hardware is attached.

BUGS
       Some of the drivers may have bugs.  See their manuals for more information.
