《Visual C++ 串口通信技术与工程实践》（代码）7.1节

VB 5.0/6.0的MSComm通信控件提供了一系列标准通信命令的接 口，它允许建立串口连接，可以连接到其他通信设备（如Modem）、 还可以发送命令、进行数据交换以及监视和响应在通信过程中可能 发生的各种错误和事件，从而可以用它创建全双工的、事件驱动 的、高效实用的通信程序。-VB 5.0/6.0 the MSComm control communications for a series of standard communication interface orders, which allow for the establishment of serial link can be connected to other communications equipment (such as modem), and also can send orders, the exchange of information and surveillance and response in the communication process may mistakes that occurred in the incident, which can be used to create full-duplex, event-driven, highly effective and practical communication program.

一个串口通信的软件，需要spcomm组件，请注意-a serial communication software, the need spcomm components, please note

485通讯接口模块的编程应用，监控显示，检测报警显示，上下值的设置输入输出的结构-485 Communications Interface Module programming applications, monitor display, alarm detection showed that the whole value of the structure of input and output settings

利用CSerialPort实现的双串口通信测试程序-CSerialPort realize the dual-use serial communication test procedures

本程序是通过串口，经由单片机控制电机转速的程序。该程序通过串口发送不同的信号，以实现控制通信。-this procedure is adopted Serial through SCM motor speed control procedures. The procedure adopted Serial send different signals to achieve control and communication.

Advantech设计的外板预警系统。通过这个可以测出部分板卡的错误信息-Advantech designed plate early warning system. Through this part can detect the wrong message board

rs485通信协议的规定，定义了串行通信协议中传输的信息内容及使用格式，可以参考-rs485 communication protocol requirements, defines the serial communication protocol to transmit the information content and the use of format

VC＋＋下的多串口通信程序，并具有其他功能-VC++ multi-serial communication program, and has other functions
