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)

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.)

vC++做上位机实现串口通讯，符合RS485通信协议(vC++ do PC Serial communication line RS485 communication protocol)

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.)

串口通信高级编程，为Visual C++.NET网络与通信高级编程范例第八章配套源代码 (serial communication programming, for Visual C.NET network and communications senior programming paradigm Chapter VIII supporting source code)

十六进制向十进制转化的程序，可用于串口通讯编程。(Hexadecimal to decimal conversion program can be used for serial communication program.)

用VC++实现的一个测试通信系统的误码率的程序，很好用的，是用两个串口的数据测试误码率的。(With VC++ realize a test communication system BER procedures, very good use, with two serial test data error rate.)

说明：  串口调试，串口设备模拟，支持32/64位系统。(Serial debugging, serial device simulation)

基于labwindows/cvi的串口通信的实现，希望对有需要的朋友提高参考(Based on labwindows/cvi Serial Communication, in the hope that there is a need to increase the references friends)

一个多线程串口编程的test，简单而实用，适合工业控制(A multi-threaded programming serial port test, easy and practical for industrial control)
