    Several buttons implementation using 3.5mm jack


    I've read the info placed here: http://www.forum.nokia.com/Technolog...onnector.xhtml
    Thank you very much for providing it.

    However, there is a problem. The OMTP specification describes only how single DIAL/END button is implemented (by pulling the microphone line to the ground). But how several different buttons are implemented? (e.g. AD-54)

    I'll appreciate if you can provide this info.

    Many thanks,
