NAME
       upsrw - UPS variable administration tool

SYNOPSIS
       upsrw ups

       upsrw -h

       upsrw -s variable [-u username] [-p password] ups

DESCRIPTION
       upsrw  allows  you  to  view and change the read/write variables inside your UPS.  It sends commands via the server upsd(8) 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.  Run upsrw with a UPS identifier to see what will work for you.

OPTIONS
       -h     Display the help message.

       -s variable
	      Specify  the variable to be changed inside the UPS.  For unattended mode such as in shell scripts, use the format VAR=VALUE to spec-
	      ify both the variable and the value, for example:

	      -s HIGHXFER=129

	      Without this argument, upsrw will just display the list of the variables and their possible values.

	      Some variables are strings, and can be set to any value within the length limit.	Others are enumerated types and can only be set to
	      one of those values.  Refer to the list to know what's available in your hardware.

       -u username
	      Set  the username for the connection to the server.  This is optional, and you will be prompted for this when using the -s option if
	      you don't specify -u on the command line.

       -p password
	      Set the password to authenticate to the server.  This is also optional like -u, and you will be prompted for it if necessary.

       ups    View or change the settings on this UPS.	The format for this option is [upsname@]hostname[:port].

UNATTENDED MODE
       If you run this program inside a shell script or similar to set variables, you will need to specify all of the information on  the  command
       line.  This means using -s VAR=VALUE, -u and -p.  Otherwise it will put up a prompt and your program will hang.

       This is not necessary when displaying the list, as the username and password are not required for read-only mode.

DIAGNOSTICS
       upsrw  can't set variables on your UPS unless you provide a valid username and password.  If you get "access denied" errors, make sure that
       your upsd.users(5) has an entry for you, and that the username you are using has permissions to SET variables.

HISTORY
       This program used to be called upsct2, which was ambiguous and confusing.
