The problem occurs when reading from COM port. Since the function get_buf()
in serial.c always return -1 in case of any error (COM port timeout, read
error, etc.), I am unable to give you any specific answer, how to make it
work.
Check if you are using the right port (/dev/ttyS0) and the port is not in
use by other programs.
If that doesn't resolve your problem, I advise you to connect to your UPS at
/dev/ttyS0 using minicom or some other serial terminal utility (use 1200
BPS, 8-bit, no parity, one stop bit, and no flow control at all). Send the
\x01 character (or Ctrl+A) to the UPS. The UPS should respond with
approximately eleven to sixteen characters of binary data (I get something
like "..||`.a@K.." in reply). You should experience connecting with
different settings until you succeed. If the working settings are different
from the above, somebody could make a new submodel in the powercom NUT
driver for you.

Simon

Subject: [Nut-upsuser] Sustainer S-1000C (Powercom protocol)
Hi,
I've sent the following message 3 weeks ago, yet have recieved no reply at
all. I don't want to nag, but could anyone please help me?
Thanks,
Dror
------------------
Hi,
I have a UPS of the Israeli company Sustainer, model S-1000C
(http://www.sustainer.co.il/data/files/specifications%20smart%20en.pdf -
don't worry, it's in english...).
I've been trying to connect to it from Debian to no avail for a long time
now.
The company has attached to it a program called Commander Pro (for windows)
and RPMs of UPSmart for old versions of Redhat and Mandrake, which were of
no use to me.
When I requested a program for Debian, they gave me "clientmate for
linux"
(http://www.icamview.com/pub/pub/netagent%20utility/clientmate%20for%20linux
%20v3.3.zip),
which is an old tarball installation that didn't work even after being
adjusted manually.
In the end I've decided to try to download the drivers from another Israeli
company, Advice, from the reasonable assumption that they probably use the
same far-eastern manufacturer, and voila: it worked! The program is Powercom
UPSMON Plus (http://www.advice.co.il/data/prog/UPSMON_LINUX.zip).
The program itself gave the following feedback:
# ./upsmon /dev/ttyS0 300 60
Copyright(c) Powercom Co., Ltd., all rights reserved.
UPSMON V0.9 program start!
UPSMON: The COM port use /dev/ttyS0.
UPSMON: Ac Fail count down is seted 300 secs.
UPSMON: UPS shutdown delay time is seted 1 mins and 0 secs.
Check UPS type.....
UPSMON: UPS Connected!!
And the enclosed upsdisp program gave the following nice screen:
UPSMON Plus For Linux V0.71

Nevertheless, I haven't managed to make NUT work with it. When I tried using
the powercom driver, I got the following response, no matter which type I
entered (including the KIN1500AP I've seen on the wayback machine had the
same problem -

Any thoughts?
Thank you,
