Hi, of the camera. digital cameras Actually, my first two cameras both connected to the host computer via RS232 (just data lines and ground) so in theory.... ;-) Newer cameras tend to have USB, but I've never used mine this way as I always remove the memory card and plug it into a card reader anyway. I've not seen any about recently, but before multi-format USB card readers became popular I remember there being numerous RS232, single format card readers on the market - I'm pretty sure Jessops used to sell them. Might be a solution.
