The "old" computer works just fine, with the same cable, same power config, etc. So this is apparently a local config issue with my new XP machine.
I compared settings between the old/new and didn't see any issues. I changed the COM port number from COM3 -> COM4, but that didn't make a difference.
This XP install is so fresh, maybe I'll let the auto updates happen and see if that helps anything.
I really don't want to go back to the old machine. It's too slow!
