MATLAB Language Using serial ports Creating a serial port on Mac/Linux/Windows


% Define serial port with a baud rate of 115200
rate = 115200;
if ispc
    s = serial('COM1', 'BaudRate',rate);
elseif ismac
    % Note that on OSX the serial device is uniquely enumerated. You will
    % have to look at /dev/tty.* to discover the exact signature of your
    % serial device
    s = serial('/dev/tty.usbserial-A104VFT7', 'BaudRate',rate);
elseif isunix
    s = serial('/dev/ttyusb0', 'BaudRate',rate);

% Set the input buffer size to 1,000,000 bytes (default: 512 bytes).
s.InputBufferSize = 1000000;    

% Open serial port
