This document was constructed from a mail from Martin. He figured out
the pinouts to make the Back-UPS RS 500 work with a normal serial port.
Here are the details:
---
UPS side PC side
RJ45 (8 pins) DB9F
1 orange/white 2,8,9
2 orange 1
3 green/white chassis/ground
4 blue -
5 blue/white -
6 green 5
7 brown/white 4,6
8 brown -

Note this results in OL=-CTS, LB=DCD, SD=ST, CP=RTS, so it should work
with the existing genericups type 20.
