visual basic+数据库access+串口+实时显示曲线(vb+database access+serial)

P2R打印机串口指令集编程手册，Olivetti/IBM/Epson(P2R printer serial instruction set programming manual, Olivetti/IBM/Epson)

vc_串口通讯，介绍了如何用VC实现串口通信的原理和源程序(vc_ serial communication, describes how to use the VC to achieve the principle and source of serial communication)

VC++的MFC开发串口调试助手源代码，包括数据发送，接收，显示制式等 (VC++ of MFC development of serial debugging assistant source code, including data transmission, reception, display formats, etc.)

Visual c++串口通信工程开发实例导航，该书采用C++编写，里面包含5个综合实例，适合有一定基础的C++人员学习(Visual c++ serial communication engineering development instance navigation, using c++, the book contains five examples of comprehensive, is suitable for the staff to learn c++ has certain foundation)

vc++制作串口调试助手，用vc6.0开发环境，一步一步教大家制作串口调试助手(vc++ production serial debugging assistant with vc6.0 development environment, step by step teach you making serial debugging assistant)

说明：  很多下位机程序员都有这样的经历，在交付工程的时候对方要求提供源程序，而大多数下位机程序员都知道交出源程序是意味着什么，所以为了保护各位下位机程序员的合法利益.这个工具，伪装过后的源程序可以编译通过。(many lower computer programmers have the same experience that the delivery of the other works on the request source, and most of the next crew to surrender programmers are aware of what it means to the source, Therefore, in order to protect you and lower computer programmer's legitimate interests. this tool, camouflage after the source compile.)

说明：  Wincc使用MSComm控件串口通讯，VB中发送十六进制数据(Wincc uses MSComm control to communicate through serial port and sends hexadecimal data in VB)

串口程序实现Ymodem协议，也可以使用TCPIP实现Ymodem协议。 串口和网络程序都可以当一个助手使用。(Serial procedures to achieve Ymodem protocol, you can also use TCPIP achieve Ymodem protocol. Serial and network programs can use when an assistant.)
