232通讯 用于电脑232通讯 可以发送和接受数据-232通讯

停车场写卡程序，不错哦-write parking card procedures, yes, oh

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-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

串口调试VB一个不错的源代码 串口中非常有用-a good VB source code is very useful in Serial

我个人收集的C++builder 多线程串口通信方面的-my personal collection of multi-threaded C builder of serial communication Wanton

我写的一个串口通信类，还是很好用的哦，大家可以参考一下-A serial port class i wrote.
