Re: UPS anyone?
-----BEGIN PGP SIGNED MESSAGE-----
Just purchased an APC Smart-UPS 620 (APC model SU620NET)
I'm running Debian slink, pretty generic system.
My specific setup has the APC-supplied cable on /dev/ttyS2 and uses the
apcd package.
I did set the port's IRQ to 0 with setserial; my system board shares the
IRQ on its two ports, and the mouse on /dev/ttyS0 gets slightly sluggish.
Though when I was testing genpower it was completely unuseable! Also
having an interrupt shared on the UPS's port seems to affect the logging.
The daemon write one line to its logfile approx. every 30 seconds with
the interrupt disabled, but with the interrupt shared, the mouse usage
seemed to prevent the daemon from polling the UPS.
The only thing untested AFAIK is actually cutting line power long enough
to initiate a shutdown, and to time the UPS under full load. I'm intending
to run three fairly low-power machines off it eventually.
So far so good. I have no way of testing if the serial port needs the IRQ
disabled with setserial in the general case. I'd do it anyway, though. :>
I'll post an update in a few days to a week or so.
