The PCI card has it's own processor, and works like it's own computer. It uses the computer's power supply, but when a box is hung, there is nothing wrong with the power-supply - it's the box - so the card can continue to run. The serial port comes straight out of the PC Weasel card, so it doesn't have to go through anything else. Also, which is cool, they at least used to ship the source code to their card (the program is stored in an on-chip flash, I think) w/ instructions on building and uploading your own version. Never tried it, but I thought it was cool. I ended up not using them because at the time they did not have a PCI version, although they do now.
