Bulldog UPS and FC1

Hi.
I put into practice the article UPS for Linux by Thomas Chung and
installed Bulldog UPS from Belkin for my F6C320-SER UPS.
I am still wondering at the result, It does not look right.
The PC does not have a modem and the UPS is plugged into the
Serial Port. I built a Null Modem serial cable to connect
the UPS to the serial port.
If I select /dev/ttyS0, the Utility Power Status and the Battery
Status say "Unknown"
If I select /dev/ttyS1 to /dev/ttyS3, then the Utility Power Status
and the Battery Status say "Normal".
I know this is not normal but I wonder what am I missing?
Should I uncross the wires on the serial cable?
I tested the cable of my APC UPS on my other computer
and they are straight-thru.
I think maybe I have not setup the serial port properly, How can I test
for it?
If I do stty -F /dev/ttyS0, I get
speed 9600 baud ; line=0;
-brkint -imaxbel
If I repeat it for /dev/ttyS1, I get
stty: /dev/ttyS1: Input/Output Error
(how do I setup minicom to capture /dev/ttyS0? I read the
manual but it assumes I am using a modem and AT commands.)
In any case, if I disconnect the power cord, I do not get
any shutdown notice.
Thanks for whatever help you can provide.
