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

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

CBC下写的串口编程，API函数实例 I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows. -CBC was under the serial programming API function examples I wish this site had been around when I was trying to figure out how to make serial communications work in Windows 95.
