SUPPORTED HARDWARE

15       The megatec driver is known to work with the following UPSes:
16
17           Maxxtro UPS 600VA
18           Mustek PowerMust 400VA Plus
19           Mustek PowerMust 600VA Plus
20           Mustek PowerMust 800VA Pro
21           Mustek PowerMust 1000VA Plus
22           Mustek PowerMust 1400VA Plus
23           Mustek PowerMust 2000VA USB
24           OnLite AQUA 50
25           Soyntec Sekury C 500
26           Soyntec Sekury C 800
27           Square One Power QP 1000
28           Tecnoware Easy Power 1200
29           Trust UPS 1000 Management PW-4105
30
31       It is also known to work with various models from Blazer, Energy Sistem
32       and Fenton Technologies. It may also  work  with  similar  models  from
33       other manufacturers, but they haven't been tested.
34
35       On  models  with  both a serial port (RS-232) and an USB port, only the
36       serial port is supported.

UPS COMMANDS

72       This driver supports some extra commands (see upscmd(8)):
73
74
75       beeper.toggle
76              Toggle the UPS beeper. (Not available on some hardware.)
77
78
79       load.on
80              Turn on the load immediately.
81
82
83       load.off
84              Turn off the load immediately.
85
86
87       reset.input.minmax
88              Reset minimum and maximum input voltage status.
89
90
91       reset.watchdog
92              Restarts the UPS watchdog timeout. The watchdog is started if it
93              isn't running, which means the UPS shuts down one  minute  after
94              this  command  is  executed  for  the  last time, restarting one
95              minute afterwards.  To  cancel  the  watchdog,  run  the  "shut‐
96              down.stop" command.
97
98
99       shutdown.return
100              Turn off the load and return when power is back.
101
102
103       shutdown.stayoff
104              Turn off the load and remain off.
105
106
107       shutdown.stop
108              Stop a shutdown in progress.
109
110
111       test.battery.start.deep
112              Perform a long battery test (Not available on some hardware.)
113
114
115       test.battery.start
116              Perform a (10 second) battery test.
117
118
119       test.battery.stop
120              Stop a running battery test. (Not available on some hardware.)
121
122

USER VARIABLES

124       The  behavior  of  the  driver can be controlled by some user definable
125       variables (see upsrw(8)):
126
127
128       ups.delay.shutdown
129              Interval to wait after shutdown with delay command (seconds)
130
131
132       ups.delay.start
133              Interval to wait before (re)starting the load (seconds)
134
135

KNOWN PROBLEMS

137       The battery charge (%) value is only a best-effort calculation and  may
138       be incorrect, or non-existant, for some UPS models.
139
140       Some  UPS  commands  aren't supported by all models. In most cases, the
141       driver will send a message to the system log when  the  user  tries  to
142       execute  an  unsupported command. Unfortunately, some models don't even
143       provide a way for the driver to check for this, so the unsupported com‐
144       mands will silently fail.
145
146       Some  models report a bogus value for the beeper status (will always be
147       "enabled" or "disabled"). So, the "beeper.toggle" command may appear to
148       have  no  effect in the status reported by the driver when, in fact, it
149       is working fine.
150
151       The temperature value is also known to be bogus in some models.
