Serial-ports

vc写的基于udp的串口通信简单实例 (Udp serial communication instance, a simple small program)

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)

MSComm控件串口通信编程，第一次作业。(MSComm control serial communication programming, the first operation.)

vb 串口上位机 很简单的一个版本，大家自己扩展功能吧 (com executed on pc,it s a simple version ,easy for expansion)

说明：  简单的串口通讯例子，有主机，目标机组成，发送数据，接受数据(Simple example of serial communication, a host, target composition, send data, receive data)

简单的串口调试，能够实行发送和接收字符。(Serial easy debugging, it is able to implement send and receive characters.)

标准串口win32接口函数,通过这些微软提供的串口接口函数可以实现对串口的读写操作(standard serial port debug source code)

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.)

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

该源码为平时所用的串口调试工具的源码，效果还是挺不错的(The source is usually used for serial debugging tools, source code, the effect is very good)
