串口通信程序，MSComm方式实现，有参考价值(Serial communication program, MSComm ways, have reference value)

Visual c++串口通信工程开发实例导航，该书采用C++编写，里面包含5个综合实例，适合有一定基础的C++人员学习(Visual c++ serial communication engineering development instance navigation, using c++, the book contains five examples of comprehensive, is suitable for the staff to learn c++ has certain foundation)

用visual c++写的串口通信程序,有rs232,同步串口通信,不错的(Written in visual c++ serial communication program, rs232, synchronous serial port communication, good)

通过和OMron PLC通讯，实时监控自动化设备运行，并下发指令控制(Through the communication with OMron PLC, real-time monitoring of automatic device operation, and instruction control)

VB和信捷PLC通讯的源代码，包括读写，置位，独一无二哦，网上都找不到的。(vb and thinget plc communication program source,good thing)

很好的串口通信源程序，可以设置端口号，波特率，数据位 停止位校验位(a very complete source serial communications,it is helpful for everybody)

串口温度数据采集并实时显示 读串口数据的原理是,只要当有数据向串口发数据来时,计算机就会自动将其数据写到一个特定的缓冲区,我们只要写程序去读那个特定的缓冲区就可以了. 有数据向串口发过来时,程序可以将数据接收到,接收的数据是字符型的,那么将数据转化为数字型的,再将这个数据的大小作为画图的某一个点的纵坐标,横坐标为数据的序号.将这些点用线连起来就是一个曲线图了,这个就是图形显示基本原理. 查看原来的数据的原理也是这样的,不同的地方就是,数据是从文件中来,同样的也是将多个数据分成一个一个的,然后这一个数据的大小就是画图的某一个点的纵坐标,横坐标同样为数据的序号,再将这些点用线连起来就是曲线图. 图形能移动的原理,是我们首先改变的只是数据,图形并没有变,但图形的形式是由这些数据来确定的,当数据发生变化后,我们通过刷新显示区来变化的.(Serial temperature data acquisition and real-time serial data reading the principle is, as long as when a serial data to the data, the computer will automatically writes data to a specific buffer, we can write specific procedures read that the buffer zone would be fine. Serial data to be sent, process data can be received, the receiving of data is the character, then transform data into digital type, and then the size of the data as a drawing of a point Ordinate, the abscissa serial data. these points will be used to link line is a curve, this is the graphic display the basic tenets. View the original data is the same principle, the difference is, the data from the file, the same data also will be divided into a number one, and then this one is the size of the data to draw a certain point )

VB写的串口通讯软件，简单易学，适合初学者(Written in VB serial communication software, is easy to learn)

实现串行通讯的相关API函数 API函数不仅提供了打开和读写通讯端口的操作方法，还提供了名目繁多的函数以支持对串行通讯的各种操作。 函数名 作用 CreateFile 打开串口 GetCommState 检测串口设置 SetCommState 设置串口 BuilderCommDCB 用字符串中的值来填充设备控制块 GetCommTimeouts 检测通信超时设置 SetCommTimeouts 设置通信超时参数 SetCommMask 设定被监控事件 WaitCommEvent 等待被监控事件发生 WaitForMultipleObjects 等待多个被监测对象的结果 WriteFile 发送数据 ReadFile 接收数据 GetOverlappedResult 返回最后重叠（异步）操作结果 PurgeComm 清空串口缓冲区,退出所有相关操作 ClearCommError 更新串口状态结构体,并清除所有串口硬件错误 CloseHandle 关闭串行口()

说明：  把串口读写函数写成动态链接库，方便在不同工程之间移植。代码测试已经通过，方便大家学习使用(The serial port read-write function is written as dynamic link library, which is convenient to transplant between different projects. Code test has passed, easy to learn to use)
