I am running two netbsd 9600's (love them PCI ports) in an APC UPS (has 9
pin output), thanks to powerhungry i386s the UPS doesnt last that long
when power goes out. We are in the heart of manhattan, in a well managed
building so there is a good chance that /if/ the power goes out, it will
be restored promptly.
Questions:
1 what software works well on netbsd using an RS232 port.
works well = can execute scripts when mains power is off, AND
battery drops below a given % of remaing charge.
(shutting down the i386s will help concerve charge)
2 what is the best way to how the box auto-poweron after
restore power.
Im considering a PIC and some Dallas Semiconductor charge controlers, but
if someone has done this before, please let me know how.
