function varargout = uartchat(varargin) % UARTCHAT MATLAB code for uartchat.fig %      UARTCHAT, by itself, creates a new UARTCHAT or raises the existing %      singleton*. % %      H = UARTCHAT returns the handle to a new UARTCHAT or the handle to %      the existing singleton*. % %      UARTCHAT('CALLBACK',hObject,eventData,handles,...) calls the local %      function named CALLBACK in UARTCHAT.M with the given input arguments. % %      UARTCHAT('Property','Value',...) creates a new UARTCHAT or raises the %      existing singleton*.  Starting from the left, property value pairs are %      applied to the GUI before uartchat_OpeningFcn gets called.  An %      unrecognized property name or invalid value makes property application %      stop.  All inputs are passed to uartchat_OpeningFcn via varargin. % %      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one %      instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES
