Here’s some MATLAB code that will read data from a Freestyle blood glucose meter that is attached to your computer via serial cable.
(Be sure to replace the “smart” quotes with appropriate single quotes. And the “…”, too. Sorry.)

% Connect to meter.
s = serial('com1', 'baudrate', 19200, ...
% Initiate communication.
% Read diagnostics.
fgetl(s); % First line is empty.
meter_ID = fgetl(s);
software_ver = fgetl(s);
current_time = fgetl(s);
num_readings = str2num(fgetl(s));
for p = 1:num_readings
reading = fgetl(s);
