RS232的串行通讯源代码~~~~~~~~~~~~，完成各种类型的串行通讯。

用Skin++做界面的一网络即时通讯软件-do interface with a network of instant messaging software

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

DNP3 Object Library Documentation (*.doc extension) 2.1 GENERAL This section describes the basic rules for the declaration of information elements. These rules have been derived from the IEC TC57 870 series of standards or drafts. These rules provide an unambiguous means of describing and representing data irrespective of its origin. Device profile documents are used to indicate the exact origin and meaning of the data object for each telecontrol device.
