vbnet与232通讯，对于用VB.NET开发串口程序有帮助-vbnet communications with 232 for using VB.NET Serial procedures help

这个是串口通信的，基于停止等待协议编写源程序，欢迎指教-this serial communication is based, stop source for the preparation of the agreement, welcomed the exhibitions

实现数据链路层 串口间的通讯，可以调试网络间的简单连接-Data link layer communication between serial port, you can debug a simple connection between networks

一个串口通信的源码，以2进制形式实现传输，可以传输图像等各种文件。-a serial communication source to the form of two-band transmission, transfer images and other documents.

本文介绍了一种新的使用串行通信进行DSP远程在线编程方法。对设计中的主要技术：DSP与PC机的串口通信、Flash编程以及DSP自引导等进行了详细介绍。结合TI公司的TMS320VC33处理器，阐述了具体的实现方法-This paper introduces a new use of serial communications DSP remote online programming method. On the design of the main techniques: DSP and PC-serial communication, Flash programming as well as the DSP, such as self-guided introduction in detail. Combination of TI

从串口读取数据，有两种方法，1、每接收一个EV_RXCHAR,就用ReadFile读一次，这样我觉得太恐怖了。2、接收到一个EV_RXCHAR后，等一定数据量的CPU周期(GetTickCount),再一次性读取缓冲区里的数据。这样做，一般情况下不会有问题，但是，如果数据很多，过了“一定数据量的CPU周期”，还没收完数据怎么办？就会少读数据了。 我用三个线程序来完成串口数据的接收，其实就是第一种方法的变种： 一个侦听EV_RXCHAR,一个对EV_RXCHAR进行分析，其实就是超时判断。如果接收到一个消息后，一段时间没收到下一个EV_RXCHAR，就认为是一个数据包的结束。这个线程就会通知数据接收线程，进行数据接收。一般同一包数据，两个字符之间的时间间隔，应该很小了吧，而两个数据包之间的间隔，应该不会太小吧！（这个地方我不清楚，猜的:( :) ）最后一个线程，是接收数据的。-read data from the serial port, there are two methods, one, each receiving a EV_RXCHAR, on the ReadFile read, I think this vote. 2, received a EV_RXCHAR after a certain volume of data, such as CPU cycles (GetTickCount), and the one-time reader, the data buffer. To do so, under normal circumstances there is no problem, but if many of the data, and after a "certain amount of data the CPU cycles," also confiscated End Data how do? Few will read the data. I used three lines to complete serial data reception, the first method is a variant : an interception EV_RXCHAR, one pair of EV_RXCHAR analys
