在mfc中进行串口通讯最简单的方法莫过于在对话框中使用MSCOMM控件了，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 、事件驱动的、高效实用的通信程序。

-Mfc carried out in the simplest way serial communication than in the dialog box controls the use of MSCOMM, MSComm communication control provides a range of standard communication command interface, which allows to establish serial port connection, you can connect to other communication devices (eg Modem) . You can also send commands, data exchange, as well as surveillance and response in the communication process with various kinds of errors and events, so you can use it to create full-duplex, event-driven, efficient and practical communication program.
