Attempt to reference field of non-structure array.
Error in serial_GUI_noICT>connectButton_Callback (line 208) serPortn = get(handles.portList, 'Value');
Error in gui_mainfcn (line 96) feval(varargin{:});
Error in serial_GUI_noICT (line 46) gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)serial_GUI_noICT('connectButton_Callback',hObject,eventdata,guidata(hObject))

Which MATLAB release are you using?
Are you getting the list of ports, COM1, COM2, and so on?
There was an old release about 5 years ago where you might have to change
serPortn = get(handles.portList, 'Value');
to
serPortn = get(handles(1).portList, 'Value');
and probably other places would need changes to. The bug was corrected in the next release (and probably in a service pack as well.)
