function varargout = SERIAL_GUI(varargin) % SERIAL_GUI M-menu_file for SERIAL_GUI.fig % SERIAL_GUI, by itself, creates a new SERIAL_GUI or raises the existing % singleton*. % % H = SERIAL_GUI returns the handle to a new SERIAL_GUI or the handle to % the existing singleton*. % % SERIAL_GUI('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in SERIAL_GUI.M with the given input arguments. % % SERIAL_GUI('Property','Value',...) creates a new SERIAL_GUI or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before SERIAL_GUI_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to SERIAL_GUI_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
