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. ------------------------------ /\_/\ |O O| pepebuho@xxxxxxxxxxx ~~~~ Javier Perez ~~~~ While the night runs ~~~~ toward the day... m m Pepebuho watches from his high perch.
