 v_charset  VARCHAR2(30)  := 'WE8PC850';
 v_port     PLS_INTEGER   := '9100';
 v_timeout  PLS_INTEGER   := 0; -- wait in seconds

                                           remote_port => v_port,
                                           CHARSET     => v_charset,
                                           tx_timeout  => v_timeout);
  utl_tcp.close_connection(p_connection);
 dbms_output.put_line(cOk);
