Yeah that's what it kind of looks like.

I had thought of that, and had turned off the UPS when switching ports.
(However I'd hope they put the extra dollar into this to make it able to
auto switch). I threw together a Windows machine today and tried to load the
drivers from the OEM cd, but it could not detect the UPS on serial
connection, but could on USB.
I dug out another serial cable too and tried that. I also managed to find an
old 28k serial modem I had, yet couldn't get that to work on either the
cables. I'm going to have to get out in the next day and pick up a new
serial cable. I'll let you know. Thanks!

I tried that, see my lasts posts for the output.

Thanks everyone!
