| Abstract: | This paper describes the design and implementation of an embedded middleware applied on the network communications. This middleware can screen the differences between the network card located in the bottom layer and the hardware module GPRS/CDMA. Moreover, it can be operated on diversified operating systems. Additionally, this middleware can sort out the problem which lies in the serial port multiplexing between SMS and wireless data traffic. What the middleware can finally do is to make the users chat with SMS and transmit network data either in the wired way or in the wireless way of GPRS/CDMA at the same time. |
