39<p>Gets the number of Session IDs in the inbox (which is equivalent to the number of times data was received).</p><p>The Session ID is generated using random numbers before searching for a communication partner. This ID is passed to the partner once one is discovered. The local host and partner then begin communication.<br />The data receiver writes its partner's Session ID to received messages. The same Session ID is written to all data received during the same CEC session.<br />Different Session IDs indicate that data was received in different communication sessions, even if the data has the same <CODE>GroupID</CODE>. You can find out how many times data was received by counting the unique Session IDs attached to the inbox messages.</p><!-- write here --></div>
