When I purchased my NEC P9100 handheld cellular about two years ago, I was interested to find that the service provider had what NEC calls a "programming battery." At first, I thought this battery must have some higher voltage to be able to program the (I supposed "older") EEPROMS in the phone. After convincing the tech to let me play with this programming battery and his VOM, I found that all this special pack did was short one of the two extra contacts in the phone's battery well to ground (to enable programming). I made some quick notes while he was programming my phone, but I seemed to have lost them. I also don't remember which of the two contacts needs to go to ground (and I never knew what the other one was for). Being able to program my phone for the system I'm roaming in to find out when I leave that system sounds like a great idea; I've been burnt by calling from a system that I didn't know I was calling from. Anyone have programming info the P9100? (P9000 is probably very similar). Also, does anyone have the pin-out (or other info) on the connectors on the P9100 that mates to the car kit? I've noticed RJ11 adapters for the P9x00, but they all interface to the car kit (which I don't have nor would want to carry around). I'd love an RJ11 off of my P9100 for a modem. Craig R.
