说明：  GPS串口通信程序，新建了一个数据库ACCESS，在显示当前GPS信息的同时可以存储以前记录过的信息，保存在数据库中，便于以后查阅。当前GPS信息包括：时间，经度，纬度，速度，真实航向以及磁偏移(GPS serial port communication program, a database of new ACCESS, show the current GPS information can be stored at the same time the information previously recorded, stored in a database for easy access later. The current GPS information including: time, longitude, latitude, speed, true course and magnetic offset)

volterra 系统的盲辨识，高阶统计随机输入(Blind Identification of Second Order Volterra SystemsWith Complex Random Inputs Using Higher Order Cumulants)

采用H323协议的ip电话通信系统，可以移植裁剪应用。(Ip with H323 protocol telephone system, portable cutting applications.)

说明：  VB写的通过串口与考勤机连接通讯的程序,便于工作查看，调试。(VB written through the serial port and Attendance Machine Connection Communication Procedures, easy to see the work, debugging.)

OPNET软件自带的General Tutorial中文译版，学习OPNET非常实用!(OPNET software s own version of Chinese Translation General Tutorial, learning OPNET very useful!)

16位CRC校验原理与算法分析，很详尽，学习CRC16的重要资料。(16-bit CRC checksum algorithm theory and analysis, very detailed and important information to learn CRC16.)

提供通讯录成员的查询、增加、更新及删除等功能。(Provide contacts membership query, add, update, and delete functions.)

Sample code in VB.NET for calculate and check CRC (Modbus specification). Supported both string format (like MSComm) and bytes array(like DCB).

可用于无协议串口调试和标准Modbus调试。例案：单片机无协议通信、变频器通信调试、PLC及工业仪表通信调试。(No agreement can be used for standard Modbus serial debugging and debugging. Example case: no agreement on single-chip communications, Converters debug communications, PLC and industrial instrumentation communication debugging.)

MODBUS通信协议，用VC6.0调试通过，非常好用，做上位机用这个很好(MODBUS communication protocol with VC6.0 debugging through, very easy to do well with this PC)
