很有名的串口类，功能封装的相当完善易用，其中还包括了流控的设置...

用VB实现RS232接口通信，能和单片机通信的上位机程序。-RS232 interface using VB to achieve communications, energy and single-chip PC communications procedures.

串口扫描程序,能够边扫描边进行数据的判断-serial scanning procedures can-while-scan data judgment

VC的COM口驱动程序,使用了ACTIVEX控件-VC COM port drivers, the use of Activex Control

详细介绍了在Windows环境下应用VC与PC机和单片机进行串行通信的几种方法，我们用visualc6.0编写了PC机与C51单片机的通信程序。经实际应用系统运行稳定可靠。

是关于中达电源通信规约的串口通信程序，功能是把电源监控器的采集数据上送到规约前置机中。-GOLD comunication rule

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

多串口调试，可以在同一个机子上连接，也可以用RS-232连接到两个机子上测试串口通讯，-Multiport Serial debugging, you can connect with a machine, can also use RS-232 connected to the two machine test serial communications,

两机串口通信 可以传送各种文件，包括二进制文件 可达RS-232最大速度-two serial port communications can be transmitted various documents, including binary files up to RS-232 maximum speed

实时控制，可根据需要增加或删除参数变量，随机曲线表示实例。-Real-time control, can be the addition or deletion of variable parameters, said examples of random curves.

RS232串口是非常有用的单片机串行通信调试器，编写的C源代码
