VB

用VB编写的FX系列PLC通信动态链接库,用户只需调用API函数就可以简单的实现串口通讯(VB prepared by the FX series PLC communication dynamic link library, Users only need to call API functions can be achieved by a simple serial communications)

实现串口通信的编程，关于类以及继承的一些使用方法，新手可以参考。(Serial communication programming, use classes and inheritance, the novice can refer to.)

VC实现和S7-200PLC的串口通信程序,很有价值哦(VC and S7-200PLC Serial Communication Program and of great value oh)

基于VC++的,多个串口的,带通讯协议的应用程序,两个通讯口,可分别接受,发送协议数据包.()

可以向串口发送数据，或从指定串口接收数据　VC源码-基础编程-源程序代码免费注册下载(Can send data to a serial port, or from specified serial ports receive data source-basic programming VC-source code downloaded free registration )

常用RS232串口通用库类，可直接使用,谢谢大家~(The common library of the RS232)

串口调试助手源码,mfc，用控件编写，包括自动发送和十六进制显示(Serial debugging assistant source)

Ymodem传输，基于VC6，可以当串口调试(about Ymodem)

串口测试程序 (Test porgram for serial)

基于VISCA协议开发，用于摄像机串口通信，控制摄像机云台等。例如：向左、向右旋转，变焦等等(Based on VISCA protocol developed for the camera serial communication control camera pan and tilt. For example: to the left, right rotation, zoom, etc.)
