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');
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.)
