NAME
       nhs_ser - Driver for NHS Nobreaks, senoidal line, with serial port

SYNOPSIS
       nhs_ser -h

       nhs_ser -a UPS_NAME [OPTIONS]

           Note

           This man page only documents the hardware-specific features of the
           nhs_ser driver. For information about the core driver, see
           nutupsdrv(8).

SUPPORTED HARDWARE
       nhs_ser supports numerous UPS models made by NHS Sistemas Eletronicos
       LTDA and marketed in Brazil. They feature a serial port and a binary
       wire protocol.

           Note

           Currently this driver only builds on Linux. This is expected to
           change in future revisions of the code.
