        Client can use this method to execute key sequence recognition.
        Key sequence may contain for example product codes etc. that
        may cause lower layers to do any specific things.

        If sequence isn't recognized this method doesn't do anything.
        If sequence is recognized then task related to the code is executed.

        Usage example:
        XQServiceRequest snd("com.nokia.services.telephony","executeKeySequence(QString)");
        snd << "*#0000#";

        If character doesn't match any supported DTMF tone
        it is ignored.

        XQServiceRequest snd("com.nokia.services.telephony","playDTMFTone(QChar)");
