 * \brief This block provides a TCP Sink block that supports
 * both client and server modes.
 * \ingroup networking_tools
 *
 * \details
 * This block provides a TCP sink that supports both listening for
 * inbound connections (server mode) and connecting to other applications
 * (client mode) in order to send data from a GNU Radio flowgraph.
 * The block supports both IPv4 and IPv6 with appropriate code determined
 * by the address used.  In server mode, if a client disconnects, the
 * flowgraph will continue to execute.  If/when a new client connection
 * is established, data will then pick up with the current stream for
 * transmission to the new client.
