用vc自带的插件开发串口通信源程序-vc onboard with the development of plug-in serial communications source

用TC对计算机的串口进行编程，并作一个简单的串口查询通讯程序。用一条九针的DB-9串口通讯线将计算机的com1口和com2口相连，com1作为接受口，com2作为发送口。-with TC on the serial port of computer programming, and for a simple serial communication program inquiries. Using a 9-pin DB-9 serial communication lines to the computer com1 mouth and COM2 I connected com1 as I accept that I send as COM2.

最棒的串口调试工具， 不用初始化任何波特率，进出的所有包都可以抓-best serial debugging tools, not initialize any baud rate, and out of all the packets can grasp

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
