Let me know. -ethan On Dec 8, 2005, at 11:40 AM, Chris McKinnon wrote: Hi, I've been looking into the Power Management APIs on OS X. I'm working on UPS monitoring software for a serial UPS and I would like to make the PM aware of the UPS. Most details I've seen about this relate to USB HID devices. I did notice on Apple's site a IOUPSPlugIn.h header. It looks like it can be used to create a plugin for ioupsd so it can communicate with the UPS. Am I on the right track? And, if so, does anyone know where I can get additional details on implementing a plugin? The header doesn't give a lot of detail.

You're on the right track. You can create your own serial UPS plugin for ioupsd, and I'll point you at the right headers and the open source code that you'll need to interface with, but we don't have all the documentation for these API's that we'd like. A UPS plugin is a CFPlugin with a few defined entry points for reading capabilities, sending commands, etc. If you haven't yet, please check out the existing USB HID UPS plugin that's part of the IOHIDFamily Darwin project. http://www.opensource.apple.com/darwinsource/10.4.3/IOHIDFamily-172.8/ IOHIDLib/IOHIDUPSClass.cpp http://www.opensource.apple.com/darwinsource/10.4.3/IOHIDFamily-172.8/ IOHIDLib/IOHIDUPSClass.h This HID UPS Plugin fits into the ioupsd plugin, as any serial or network UPS plugin would. One importante difference is that OS X cannot automatically detect the presence of your serial UPS, so you'll need some software entity (a daemon, or a process launched by launchd) to ping ioupsd and tell it to load your plugin.
