function DisplayTrack(port) 
% DISPLAYTRACK Display track log data from GPS on the given serial port 
 
% A program that uses the serial port follows a five-part pattern: 
%  1. Create a serial port object. 
%  2. Connect the serial port object to a device. 
%  3. Optionally set device properties. 
%  4. Communicate with the device (read and write data) 
%  5. Disconnect from the device and clean up 
 
% Connect to the GPS. This function implements parts 1-3 of the serial  
% object usage pattern. 
[gps, pid, version, text, protocols] = OpenGPS(port); 
 
% Get the track log data from the GPS (this is part 4 of the pattern) 
tracks = ReadTracks(gps); 
 
% Close the connection and clean up (part 5 of the pattern) 
CloseGPS(gps); 
 
% Analyze and display the track log data. Not part of the pattern, but a 
% program that reads data and does nothing with isn't very interesting. 
AnalyzeTracks(tracks);
