Modem_source

实现串口通信功能 基于MFC的对话框，程序简单易懂 适合初学者(Serial communication functions based on the MFC dialog box, the program is easy to understand for beginners)

Ymodem传输，基于VC6，可以当串口调试(about Ymodem)

最新版CSerialPort类(2014年)，还包含一个旧版本,可以进行比较使用。(The latest version CSerialPort class (2014), also contains an older version. Use can be compared.)

串口通讯调试代码，包括端口设置界面和信息收发界面(Serial communication debugging code, including port settings interface and messaging interface)

可虛擬兩個RS-232或者是多個RS-232互傳資訊，此源码維VisualC-6所編寫。(Can be a virtual two RS-232 or RS-232 over pass each other information, this source code written by Victoria VisualC-6.)

说明：  介绍DSP与上微机的串口通信和功能设置，及通信调试(introduced DSP and PC on the serial communications and functionality, and communication Debugging)

说明：  Testing PC to DVP PLC connection

实例321——利用MSComm控件进行串口通信(Examples 321 use MSComm control serial communication)

这个程序是利用VC编写的一个从机串口响应modbus查询命令程序，实现RTU方式，3.5和1.5个字符时间检测，CRC和LRC校验。(This program is written using VC as a response from the machine serial modbus query command procedure, to achieve RTU mode, 3.5 and 1.5 characters time detection, CRC and LRC check.)
