 So the only command line change would be to go from
 
  --native=socket,in,30,,5500,udp --fdm=external
 
 to
 
  --native=socket,in,30,,5500,udp --fdm=null

 btw, do we have an 'official' port number assignment ? Over the time I
read several suggestions by several members over the use of port 5500:

--props=socket,bi,5,localhost,5500,tcp 
--nmea=socket,out,2,localhost,5500,udp
--httpd=5500
--native=socket,in,30,,5500,udp --fdm=null
[... maybe some more ...]


It would be useful at least to postulate a FlightGear assignment - it does
not have to meet RFC1340

Actually I don't think 5500 is a good idea - it is already assigned to 
someone else:

  fcp-addr-srvr1  5500/tcp   fcp-addr-srvr1
  fcp-addr-srvr1  5500/udp   fcp-addr-srvr1

(see http://www.iana.org/assignments/port-numbers).

Unless and until we have an assigned number, we should use a number from 
the Dynamic and/or Private Ports range: 49152 through 65535.  So 55000 
would be OK!  Of course you can use any number you like on a private 
network (not connected to the Internet, and where you know that the port 
you choose is not in use by any other protocol) or when you know that 
the machines sending and receiving are not going to use that other protocol.

There is actually a reasonabe chance that an assigned port number would 
be granted if we requested one.  My company recently got one, even 
though I was expecting we wouldn't be able to justify the need for it. 
However, I don't think it would be appropriate until the protocol has 
settled down and been used for a while.

So may I suggest changing the suggested number to 55000 in the documents 
that mention it?
