Where can I find information that describes the physical interface to Nokia cell phones? The physical interface I am interested is the port that the cable connects for transmit/receive audio, signaling control for on/off hook, dial digits transmission, etc.
Thanks for the help.
RE: Cell Phone Cable Jack Interface
Such interface specification is Nokia propriety and because of this it is not publicly available by Nokia. For controlling the Nokia phones you can use phone specific cable provided by Nokia and phone software or AT-commands.
