NAME
       liebertgxt2 - Driver for Liebert GXT2 UPS, using the ESP2 serial proto‐
       col

NOTE
       This man page only documents  the  hardware‐specific  features  of  the
       liebertgxt2 driver.  For information about the core driver, see nutups‐
       drv(8).

SUPPORTED HARDWARE
       liebertgxt2 is experimental and will recognize only those models	 known
       to  work.  The driver will report the model it finds and abort if it is
       unknown. modelname= in ups.conf can be used  to	force  the  driver  to
       accept the model as supported.

       The  driver is incomplete but supports the numerious information fields
       and fields necessary to make the driver useful. Potentially useful fea‐
       tures that aren't supported are shutdown and battery test - or any com‐
       mand that instructs the UPS to take some action.

CABLING
       This driver expects to see 2400 baud serial data	 at  the  TX/RX	 pins.
       This driver was tested with an original cable.

EXTRA ARGUMENTS
       This   driver   supports	  the	following  optional  settings  in  the
       ups.conf(5):

       modelname=model
	      Force the model name of model to be a  supported	model,	giving
	      you the chance to try this driver with your Liebert UPS.

BUGS
       Action commands are not supported, that includes battery test and shut‐
       down.
