Hello Arno,
FreeNAS doesn't come with a compiler and I had to compile with the patch
on FreebBSD-9.3 and then copy the produced mge-shut. Unfortunately it
didn't work out. For every try I was getting "Connection Refused" and
when I tried /usr/local/libexec/nut/mge-shut -D -a <ups_name> I was
always getting 'No matching HID UPS found'.
I returned back to the USB connection now which seem to work better.
Thank you very much for your help anyway.
Best regards,
Panagiotis

Hello Arno,
Can apply the patch directly or should I recompile nut?
not sure to fully understand your comment, but...
this is a source code patch, so you indeed have to apply it to the NUT
source code (from within the source tree, "patch -p1 <
../path/to/patch_file), and then recompile (make, at least, or configure).
note that the configure flags should be adapted to your specific
distro to ensure easier testing.
not sure about FreeNas ones, but that can be found in their package repos.
cheers,
Arno

Hello Arno,
Question: have you also tested oldmge-shut?
Otherwise, that might be interesting to do so and send
back the results of these tests...
Yes, I've tried this as well with worse results
unfortunately. This driver seems to be even more unstable.
When it gets able to set communication with the UPS (which is
not always the case), it usually lost it again after a while.

It there a possibility to be an issue of the UPS, or the
connection between the serial port of the machine and the UPS?
thanks for the confirmation with oldmge-shut. I'm not astonished
on the results, but was worth a try.
I've double checked the related code difference for mge-shut
between 2.7.1 and 2.7.2.
Again, the only diff I see is the one pointed previously
(setline...).
So, it would be great if you could test this patch (through some
reboots) and report back.
Then, I don't think it's an issue with the device.
There is a long run TODO (mentioned in the header of libshut.c)
that is the baudrate negotiation.
The driver still communicates at 2400bauds, which is not that
much for such verbose units. We could go at least for 9600 on
these units, which is 4 times faster already.
This may cause some slowness and behavior issues as you're
experiencing, under some circumstances.
For example, the test using a 5SC750 on Linux (Debian Jessie)
shows that report descriptor (size 1538) takes ~10 seconds to be
retrieved, which is quite long.
Then, even if this "new"mge-shut is a lot better than the
oldmge-shut, it can still be perfected on the error handling (and
not optimal cases), which you may be hitting.
And finally, the notification handling could also help to poll
less the unit, while being notified of critical status changes.
cheers,
Arno
