UDP_Example_Echo.m

% Example for an echoing UDP implementation
%
% Create a simple UDP instance listening on the loopback interface on port
% 11724. Use an TCP/UDP test tool (e.g. Packet Sender
% https://packetsender.com) to send single UDP datagrams to this instance.
% The instance will echo the incoming data back to the sender...
