I'm interested in building one of these SIO2PC connectors- http://www.stephens-home.com/sio2usb/
I don't have an SIO cable, so I was just going to get M/F jumpers and connect them directly into the SIO port of the computer. So my question is, is the SIO cable straight-through (meaning is the pinout for the computer's SIO port the same as the end of an SIO cable)? If not, could someone supply me with the port's pinout?
