Okay, I've now got my Polaroid 640 PDC plus working with Gphoto v.43, and all is well... ;-) I ended up disabling onboard serial port 1, and using "auto" on port 2. <embarassed mode on> I umm....also....ahem, got the 1/8 inch mini-jack serial port cable correctly plugged into the camera...(it took a lot more force than I ever imagined, and a final "click") <embarrassed mode off> ;-) -- /\ Dark><Lord \/
