I have tried both the default windows port settings of 9600, 8, None, 1, None and a configuration I found on a website of 2400, 8, None, 1, Xon/Xoff. I have not found any documentation from APC on what settings to actually use. I have also tried using the PowerChute Business software, but it did not work either. Today I will try using the UPS with a different computer to see if the serial port on the server is bad.
