I made an adapter gizmo with resistors and diode. Re-booted (just as a precaution), and simulated power-fail and low-battery. Still, my system won't shut down. I verified that the daemon is running with genericups 5. It does not seem right that upsc and upsct fail, as below: alta@alta1:~> upsc localhost Unable to get variable list - Receive timeout alta@alta1:~> upsct localhost Unable to connect to localhost - Connection failure: Connection refused Hmmm, I wonder why they would have trouble with localhost. Like port numbers not matched, or blocked. I'm not real knowledgable in this area. ... Reed, alta@alta-research.com On Friday 15 February 2002 13:05, you wrote:

Great information. Good to know TrippLite responded.
genericups 5 puts -12 on SD, +12 on DTR, and -12 on RTS. This all makes sense to me (and is compatible with measurements) for genericups 5 except for one bad thing: If I simulate AC Fail and Low Batt by feeding -12 volts to computer pins 1 and 8, my computer does not shut down. The daemon is running, but no cigar.
Do you have the resistors between 4 and 1 and 4 and 8 when you are testing? I would think that they would have to be present for the software to detect a valid level change. RS-232 inputs can swing either way if they are simply open circuited. Applying the -12v to 1 and 8 might not actually be changing their states.
