Just enough information to...make you wish you had the information you actually need. Worthless :-(
What is NECESSARY is what the UPS send out on the serial line to indicate that line power has been lost.
And then you'll find that many PCs do not have a serial port.
Universal SERIAL Bus. I never realised that it doesn't count as a serial line. If it's connected by USB, then the manufacturer can damn well describe the data that passes across it when it talks to a windows machine. It's not like we're talking about some super-secret communications protocol which, if publicly revealed, would give significant aid to competing companies.
The usb method is the way of things to be, and besides, can give you more info, like current AC voltage, state of the battery, remaining on battery time (so that the driver decides when to power off safely)...
Only if the manafucturer describes the format of the communications protocol
Just a single line to tell you that you are running on batteries is insufficient nowdays.
I wasn't talking about using an RS-232 line...I'm talking about describing the data that the damn thing puts onto the USB line. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
