This is callback function called by the system whenever out of band data from the TCP/IP stream is received. A descendent class may interpret this data according to the semantics of the high level protocol.

The default behaviour is for the out of band data to be ignored. <dl compact><dt><b>Parameters: </b></dt><dd>
