As far as I know, a special cable _is_ required.
The APC user manual is full of warnings about using the correct cable.
My UPS came with power-chute bundled so I have the cable.
While waiting for my UPS to arrive, I tried using a normal cable and
an rs232 break out box to see what I could see on one of the UPS's at
work. I managed to power off the UPS :-)
Page 27 shows pinouts (of sorts) for the DB9 connector, how this
relates to rs232 I'm not sure. But with the correct cable the host
sees a simple rs232 connection.
My UPS is being monitored by my sun386 as zen didn't have a spare
serial port... so the script works on _anything_ :-)
