The Application of Asynchronous Event Driven Model In Embedded System Sha Quan (Shanghai Institute of Technology) Abstract：The application of asynchronous event driven software model in embedded Linux platform can use less system overhead and improve the efficiency of the program. This paper presents a method to realize the asynchronous event
driven software model in embedded Linux system ,which using the functions of serial interface in the library libcssl. The application in GSM short message sending system which using the siemens MC35 as the data source, shows the design method and its realization.
