Software used for controlling and data logging lab equipment.

function tempobjdisconnect(serialObject)
% TEMPOBJDISCONNECT terminates communication with Eurotherm controllers
% tempobjdisconnect(serialObject) terminates communication with Eurotherm series
% 2000 temperature controllers, given serialObject as a valid temperature
% controller serial object (generated by tempobj).

% e.g. tempobjdisconnect(tempobj(7)) - terminates communication with the
% temperature controller attached to COM7

% Range:

% tempObj = valid serial port object

% checks the number of arguments
error(nargchk(1, 1, nargin))

% error handling
if ~isserial(serialObject) || (~isfield(serialObject.UserData, 'realTermHandle') && ~isrunning(serialObject))
    % errors if the realterm handle isn't there, and the serial object is
    % closed

if isfield(serialObject.UserData, 'realTermHandle')

    realtermfclose(serialObject.UserData.realTermHandle, serialObject.UserData.captureFileID)

    % closes communication conventionally

% deletes it afterwards
