1 两路编码器输入通道 2 采用专用编码器计数芯片完成计数工作 3 与上位机串口通讯(1 two-way encoder input channel 2 using a dedicated encoder chip count as counting work 3 serial communication with the host computer)

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)

用vb6.0做的一个小的串口测试程序.可以实现正常通信(Used vb6.0 to do a small test program serial)

串口通信，对串口发出的数据进行读取和处理，进行检测(Serial communication, read and process the data sent by the serial port, and detect it.)

visual basic+数据库access+串口+实时显示曲线(vb+database access+serial)

VC++串口上位机程序编写，很详细，初学者编写上位机适用(VC++ serial PC programming, in great detail, the preparation of PC suitable for beginners)

改进的SerialPort类单文档实例程序(improved SerialPort single document type sample program)

VC串口通信modbus协议源代码,测试可用。(modbus通信协议)(VC serial communication protocol source code modbus)

VB环境下简单的串口测试程序，测试两台主机通过串口是否能够实现数据传送，可以传送数字、字符串及汉字。(VB environment, a simple serial test program, test whether two hosts can be achieved through the serial data transfer, can send numbers, strings and characters.)
