GPRS数据中心源代码

实现串口通信 可以收发数据 可以是数字也可以是ASCII(Serial communication)

Visual C++高级开发范例解析第二章ActiveX源码(Visual C++ Advanced Development ActiveX sample chapter source analysis)

朋友写的C++645通讯程序，支持645-1997与645-2007,支持自已组帧程序自动添加校验码通讯，可以增加数据标识定义，里面还有部分关于费控通讯代码，挺好，拿来分享(Friend write C++645 communications program to support the 645-1997 and 645-2007, to support their own group the frame program automatically adds the checksum communications, can increase data identifies the definition, there is also a section on the fee control communications code, good for them and share)

一个事件提醒程序,类似于手机中的事件提醒(An event to remind the procedure, similar to events in the mobile phone to remind)

这是外汇活动中的一种 可以从多种货币的汇率差异中,获得利润(This is one of the foreign exchange activities that can be profited from the exchange rate differences of multiple currencies.)

pwm整流器的建模仿真，感应双馈发电机系统的仿真，复化三点Gauss-lengend公式求pi。( Modeling and simulation pwm rectifier Simulation of doubly fed induction generator system, Complex of three-point Gauss-lengend the Formula pi.)

modbus rtu 校验vb源码，对VB学习者很有帮助(modbus rtu checksum vb source code, useful for VB learner)

自己整合的，可直接下载调试使用，傻瓜式文件一体包。(Integration of their own, can be downloaded directly debugging use, fool file integrated package.)

该程序实现水声信道的模拟方法及性能分析，提出了一种信的水声信道模型(The program implements underwater acoustic channel simulation methods and performance analysis, presents a letter of underwater acoustic channel model)

C# 串口通信源码示例，老外写的，非常精美。(Serial Communication C# source code examples, written by foreigners, very fine.)
