My 6310i doesnt detect the serial cable when i plug it in. My dads 6210 works with it though and the cable has worked with my 6310i once or twice so i know the cable is OK. It's like a 1 in 10 chance that when i connect the cable it will work.

I've heard off a few people that 6310i dont work with data cables and u need IR or BT


Please help! i cant afford IR or BT connections
