[Nut-upsuser] mge-shut driver fails almost after every reboot

Hello all,

OS name: FreeNAS 9.3
NUT version: 2.7.2
NUT installed method: Bundled with FreenNAS 9.3
Device: EATON 5SC 1000 
(http://powerquality.eaton.com/Products-services/Backup-Power-UPS/5SC.aspx?cx=5&wtredirect=www.eaton.com/5SC&GUID=B81251A4-F34E-4373-94B3-B4FB3D0CBCA8)

Problem description:

This was originally reported as bug to FreeNAS 
(https://bugs.freenas.org/issues/8049#change-41087) and was asked to 
post this upstream, so here it goes.

The issue with the driver has been seen in FreeNAS 9.3-STABLE. While the 
serial connection with the UPS (Eaton 5 5SC Serial with mge-shut driver) 
is working initially, almost after every reboot, the driver is failing 
with the message "UPS failed - Driver not connected". This was not the
case with FreeNAS 9.2 and NUT 2.7.1.

Additional information:

Network UPS Tools - Generic HID driver 0.38 (2.7.2)
SHUT communication driver 0.84

The only diff I see between shut in 2.7.1 and 2.7.2 is the following:

--- ../nut-2.7.1/drivers/libshut.c    2013-10-02 14:16:42.000000000 +0200
+++ drivers/libshut.c    2014-02-25 16:39:34.000000000 +0100
@@ -312,7 +312,7 @@
     /* FIXME: add variable baudrate detection */
     *upsfd = ser_open(device_path);
     ser_set_speed(*upsfd, device_path, B2400);
-    setline(*upsfd, 0);
+    setline(*upsfd, 1);

     /* initialise communication */
     if (!shut_synchronise(*upsfd))


This is tied to the PnP feature, and was reverted with the following commit:
https://github.com/networkupstools/nut/commit/75b0ce8b952d7c55880f7a019ba61ec05b45e6a7

Never had time to get the complete consideration on this, so I'm still
lacking visibility.
it's still unclear to me why it does not work for you. Is FreeNAS linux
based or BSD?
I've just tested a pristine 2.7.2 on Debian Jessie + 5SC700, and it works
fine.

would you be able to test a patch or a git branch?

thanks and cheers,
Arno

[Nut-upsuser] mge-shut driver fails almost after every reboot

Hello Arno,

Thanks for the quick reply. FreeNAS is FreeBSD-based.

Yes, I could test a patch.

As I have mentioned, this behavior is not seen at every single reboot 
but after most reboots. Also, some times, the connectivity can be lost 
without even rebooting. That is not very often can have happened a few 
times.

Best regards,
Panagiotis
