Pin 4 (on the back of the Pilot) is the HotSync input; pin 9 is +3.3V. As you know, when they"re connected, the Pilot starts a desktop HotSync. If Pin 3 (GP Input) and 4 are both connected to pin 9, the Pilot will do a Modem Hotsync.
On the PalmPilot one can change what the "Cradle HotSync button" and the "modem hotsync button" does; i.e., run something other than HotSync. So,depending on whether the GP Input is active or not, the Pilot can do two different things." This information should be correct, but may be not. You can help us to improve this webpage!
