ALC Extended Dimming problems

Hmm...this is interesting. I'm suddenly starting to get a lot of bad messages from the HLC, and that connected to a RS232 port on my PC. Granted, it *is* a PCI RS232 addin card, but I didn't think I had problems with that before. In fact, I'm sure I didn't, as I've never had an abundance of native (motherboard) RS232 ports, so I'm sure I've used the HLC on these connections before. But suddenly it's giving me the weird messages. I wonder if my serial expansion (or HLC) is on its way out.....
