基于TCP的MODBUS协议开发。不但有源代码模块，还有文档说明

中国移动CMMPV4.8和开发文档使用示例对短信开发有很大帮助。中国移动通信CMPP3.0短消息网关开发接口库 V4.8-China Mobile CMMPV4.8 and development of documents using the example of the message the development of much help. China Mobile Communications CMPP3.0 Short Message Gateway Interface Library V4.8

不错的客户端连接程序，希望大家喜欢，里面是一个客户端的程序，一会会提供服务端的程序-good client procedures in the hope that everyone likes, there is a client process, will provide a service side of the process

GSM通讯源码，采用C++语言，用VC6.0编辑器编写的代码，对于挂接GSM模块后，能正常的与手机进行短信的收发，才用消息队列，开辅助线程对短信进行接收、解析、读取，对发送短信和接收短信，都采用消息队列的模式进行收发。非常好用。对搞GSM模块上位机开发的程序员非常有帮助
