是本人的一个正式项目中所做的测试工程源码。主要功能是通过串口与板子的GSM模块进行通讯，进行收发短信的程序。内容有：串口设置，GB2312与UNICODE编码转换，PDU编解码（此部分大部分借鉴了网友的代码）,AT指令发送。因内部使用了MultiByteToWideChar、WideCharToMultiByte字符转换函数，所以不能直接向嵌入式程序中移植。想要做这方面移植的请参考与本人上传的另一个资源“ HZTableComHelp.rar”-Is my project done by a formal evaluation of the source. Main functions of the board through the serial port and the GSM communication modules for the process to send and receive text messages. Are as follows: serial port settings, GB2312 with UNICODE encoding conversion, PDU codecs (most of this part of the code from the User), AT commands to send. Due to the internal use of the MultiByteToWideChar, WideCharToMultiByte character conversion function, it is not embedded directly to the transplant procedure. Want to do in this regard please refer to the transplant and the other resources I uploaded " HZTableComHelp.rar"
