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.
<br>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!
