串口自动检测

串口调试，visual basic撰写，可以发送包括word格式，excel格式，text格式等文件(Serial debugging, visual basic writing, including word format can be sent, excel format, text format file)

说明：  Wincc使用MSComm控件串口通讯，VB中发送十六进制数据(Wincc uses MSComm control to communicate through serial port and sends hexadecimal data in VB)

利用VB语言实现对串口进行操作，从而实现通过串口进行远程关机的操作，了解相关编程方法。(VB language serial port operation through the serial port for remote shutdown operation, understanding related programming methods.)

通过和OMron PLC通讯，实时监控自动化设备运行，并下发指令控制(Through the communication with OMron PLC, real-time monitoring of automatic device operation, and instruction control)

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.)

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)

利用MSComm控件实现字符型数据发送与接收(MSComm control to achieve the transmission and reception of character data)

耀华表通信控件 内置了地磅的串口协议。能自动读取指定的数(Communication control Toledo Electronic loadometer, serial direct source reading program. The source without any Dll, built-in serial port loadometer agreement. Can automatically read the specified binary readings.)

labwindows 串口编程 简单易懂 做虚拟仪器的同学可以看看 或许对你有用(programming straightforward labwindows serial do virtual instrument students can take a look at perhaps useful to you)

说明：  自动识别电脑有多少个串口，关自动加载!!!(Automatically identify the number of serial computer, turn off automatic loading )
