Well, it might not be what you expected, but I have a new problem :

I did something like this :

# upscmd ups1 at localhost test.battery.start

(some time later... )

# upscmd ups1 at localhost test.battery.stop
(ups1 is the MicroDowell )

there were no messages , but asking for parameters got me this ...
# upsc ups1 at localhost
battery.capacity: 7
battery.charge: 0.0
battery.charge.low: 20
battery.packs: 2
battery.voltage.nominal: 12
driver.name: powerpanel
driver.parameter.port: /dev/ttyS0
driver.version: 2.0.5
driver.version.internal: 0.12
input.frequency: 0
input.frequency.high: 63
input.frequency.low: 47
input.transfer.high: 272
input.transfer.low: 180
input.voltage: 0
input.voltage.nominal: 230
output.voltage: 0
ups.firmware: 2.107
ups.load: 0
ups.mfr: CYBER POWER
ups.model: 1000VA
ups.power.nominal: 1000
ups.realpower.nominal: 700
ups.serial: 000000000000
ups.status: OFF
ups.temperature: 0


Obviously, the ups is still providing power(it's the only power source for this computer).
I've tried to restart the driver and got this :

Network UPS Tools - UPS driver controller 2.0.5
Network UPS Tools -  CyberPower text protocol UPS driver 0.12 (2.0.5)
Warning: This is an experimental driver.
Some features may not function correctly.

warning: sent "\r", expected "#2\r" but got ""
warning: sent "P4\r", expected "#<something>" but got ""
Unable to detect a CyberPower text protocol UPS
Driver failed to start (exit status=1)

I'm not sure what the problem is ...
as for solving it, the "windows solution" of restarting the whole thing (ups+computer) would probably work,
but it's not pretty ... (not to mention inconvenient , as the system is in a remote site, with no easy access)
