Pin 15 - connect to ground if you want your palm to sense I'm in craddle. Usable in many programs.
Please note, that as of the 3rd of August 2006 all the Palm documents number the pins in the opposite direction.

SOLUTION: If you were unlucky enough to buy this cable, and you have a few minutes, it is possible to fix the cable to work. I believe the problem is that this cable has pin 6, which is the hotsynch pin. Typically, if your cable has a hot synch button, this pin grounds out to activate the synch. Although the pin connects to nothing in the cable, its presence causes problems. Removing it corrected the problem for me at least.
HOW TO DO IT: If you have tweezers or a tiny pair of pliers, count from the side OPPOSITE the power connector (big square peg) to the SIXTH pin. Pull this pin out. I couldn't get it out from the outside, so I just popped open the connector. To open the connector, there are is a little plastic flap on each side holding it together - open these (I just broke them) and pry hard and the case will pop open. Form there I just used tweezers to pull out the sixth pin from the inside, and put the case back together. Voila! It works.
