can't connect to an Eaton Powerware 9155 over a usb-serial adapter
hello everyone, I've been testing the NUT solution as opposed to the undocumented LanSafe application to control my Eaton UPS. I am on a Slackware 13.37 system with a 2.6.37.6 kernel. NUT version is 2.4.3 . I installed the tarball by compiling it directly on my system (as a slackbuild package). The UPS is an Eaton Powerware 9155, but I don't know how to obtain the manufacturing date. The

It looks like the simplest way to handle this on Debian is to add the system 'nut' user to the 'dialout' group: $ sudo adduser nut dialout > I have been meaning to collect some

Help with USB-to-serial cable
I am trying to use software to program a scanner radio (BCD396t and UASD software). The software installs and seems to run properly, reading and writing database files.

USB and serial
Hello, everyone - I have an old Windows app - a ship navigation program - that needs to see GPS input on a serial port (it was written in the pre-USB days.) My laptop, however, has no serial ports - but this same program, when run on a friend's Windows box, can read the GPS info from the USB-connected GPS via the "USB-Serial Driver". This is one of the frustrating bits of this

NUT support for APC BackUPS Pro 900VA
Hi all, I'm trying to configure Nut to connect to an APC BackUPS Pro 900VA. This ups uses a serial port on which _simple_ or _smart_ signaling should be spoken. I've connected the UPS to a serial port using the original 940_0128A cable from APC. Unfortunately I've not yet managed to read any data from the ups. If I try to load the apcsmart driver it tells me that it cannot communicate

And now onto the palm pilot with Kpilot
I've looked up the Kpilot manual, and I think I have an okay idea of what's going on with it. I'm trying to get it's detection feature to find my Palm Pilot. CentOS does seem to be able to recognize it, because if I run lsusb when running a hot sync, I get the following: [root at localhost dev]# lsusb Bus 001 Device 010: ID 0830:0060 Palm, Inc.

APCsmart serial port problem
I have a new APC Smart-UPS SUA2200RM2U. I've had no success with the manufacturer's PowerChute software and smart signaling, so I have decided to try NUT. The smartups driver can't make contact through the serial port. Since this is rack-mounted, it comes with a 940-1524 serial cable. As far as I can tell, this is supposed to work with smart signaling. Here's my ups.conf:

Wine + winebottler + azloader.exe + rs232 to usb, adapter
Ubuntu creates /dev/ttyUSB0 for me when I plug in the usb-to-serial-adapter. I have a symbolic-link to /dev/ttyUSB0 from 'dosdevices/com1'. What is new in 10.04 Ubuntu is that I have to sudo chmod o+r and sudo chmod o+w on /dev/ttyUSB0 every time before I start the app which uses that serial line. ttyUSB0 goes away when I unplug the serial adapter from the USB port or shut down the

[RFC apcsmart V3 00/18] apcsmart driver updates
Sorry for a bit longer delay than I anticipated, I was stuffed with the work. This is the next iteration of the patch adding some functionality to apcsmart driver, and relying on 'ignorelb' recently added. Follow up from previous thread: http://www.mail-archive.com/nut-upsdev at lists.alioth.debian.org/msg02331.html Main differences is that V3 is split into many small patches, so the
