I was having a hell of a time getting any response from the drive in terminal using an original Nokia CA-42 cable; but I thought I would share some of my research. If you bought an original Nokia CA-42 (and not a cheaper eBay type) adapter a few things are needed to make things work. 1. Download drivers from: http://europe.nokia.com/A4144937 2. Splice wire. BLACK -> GROUND WHITE -> RX BLUE -> TX YELLOW -> (TO 3.3V BATTERY NEGITIVE) RED -> (TO 3.3V BATTERY POSITIVE) 3. Ground needs to be connected to the PCB in order to get a response from terminal. No ground, no go. BTW: I also purchased: FM232RQ (which is the really cool small thing) and a FM242RL. They do not work; do not waste your time.
