I've got a serial card in front of me that has what looks like a model number which says PCI-232/485,2CH. This makes it SEEM like it ought to be able to do 232 or 485, but I can't fine any jumpers or settings in the software to change it and the drivers default to 485. Can this board do 232? I took a couple pictures so you can see the card I'm talking about:

Sorry the quality isn't better, it's the best this cheap digicam can do. =P
