ISE4/ISE6 - Set Network Parameters
++++++++++++++++++++++++++++++++++++

This sets "Network Configuration" found on the Data Output page of X-Plane, and informs X-Plane
the destination IP and port for bulk data. (See :doc:`DATA* <dsel>` for bulk data info.)

:Send:

   You set IP and port, which may be different from where you're invoking the command. For
   UDP data, set the cmd=64.

   To stop sending data, set the final parameter to 0.::

     cmd = 64
     msg = struct.pack('<4sxi16s8si', b'ISE4',
                       cmd,                  # =64 for UDP data
                       ip.encode('utf-8'),   # e.g., b'192.168.1.5'
                       port.encode('utf-8'), # e.g., b'50987'... characters, not an integer!
                       use_ip)               # 0=disable, 1=enable
     sock.sendto(msg, (beacon['ip'], beacon['port']))

   ISE6 is similar::

     cmd = 64
     msg = struct.pack('<4sxi65s6sxi', b'ISE6',
                       cmd,                  # =64 for UDP data
                       ip.encode('utf-8'),   # e.g., b'fe80::8f6:826:b4e1:76e3'
                       port.encode('utf-8'), # e.g., b'50987'... characters, not an integer!
                       use_ip)               # 0=disable, 1=enable
     sock.sendto(msg, (beacon['ip'], beacon['port']))

Note that the port# of your socket can be found as ``sock.getsockname()[1]``
