    44         Client can use this method to execute key sequence recognition.

    45         Key sequence may contain for example product codes etc. that

    46         may cause lower layers to do any specific things.

    47 

    48         If sequence isn't recognized this method doesn't do anything.

    49         If sequence is recognized then task related to the code is executed.

    50         \param  keySequence          Key sequence to execute.

    51         \return True if key sequence was processed, false otherwise.

    52         

    53         Usage example:

    54         XQServiceRequest request(

    55             "com.nokia.symbian.IDtmfPlay",

    56             "executeKeySequence(QString)",

    57             true);

    58         request << "*#0000#";

    59         QVariant keySequenceProcessed;

    60         bool requestOk = request.send(keySequenceProcessed);
