I've had this 9pin - 25pin cable around for ages, and I always thought it was a 9pin - 25pin serial cable. Problem is, it never seemed to work any time I used it, I always figured there was a software problem. So tonight I broke out the multimeter, and tested away. Aparently its not even close to a serial cable, I've never seen one like it.

Here's the pinout I made of it - http://john8520.homeunix.org:8888/files/cable.txt

Thoughts on as to what it might be?
