OK... I'm going to try with a BK650EI (CS series) from APC...
( http://www.apc.com/resource/include/techspec_index.cfm?base_sku=BK650EI )
It's got USB and RS232 cables, so the RS232 drivers should work direct.
And it'll drive 200 W for about 10 minutes... and 400 for about 2
minutes... so plenty of time to shut down the server even if it's at
full load (less than 300 W I gather).
And it's cheap. :)
I'll feedback here once the device is plugged in, and drivers (ups-nut)
built and configured and running...
Wish me "uninterruptible" luck!
