串口打印指令源码，例程程序结合易语言扩展界面支持库，使用端口发送打印指令。(Serial print instruction source, routine program expansion interface combined with easy language support library , using the port to send print commands.)

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.)

说明：  很多下位机程序员都有这样的经历，在交付工程的时候对方要求提供源程序，而大多数下位机程序员都知道交出源程序是意味着什么，所以为了保护各位下位机程序员的合法利益.这个工具，伪装过后的源程序可以编译通过。(many lower computer programmers have the same experience that the delivery of the other works on the request source, and most of the next crew to surrender programmers are aware of what it means to the source, Therefore, in order to protect you and lower computer programmer's legitimate interests. this tool, camouflage after the source compile.)

实现串口通信功能。由中断程序调用，实现串口单字节读写的功能。(Realize the serial communication function. By the interruption of the procedure call, the realization of single-byte read and write serial port function.)

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.)

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 )

读取串口调试助手保存的TXT文档，将连续两个8位合并为一个16位数据，然后进行图形化显示，分析了幅频特性，然后对其进行了低通滤波并画图(Read the serial debugging assistant TXT files saved in the continuous two 8 into a 16-bit data, and then graphically analyzed amplitude-frequency characteristics, and its low-pass filtering and drawing)

说明：  C#串口通信，新手必看。新手入门，你值得拥有(C # serial communicationNovice must see. Novice, you deserve it)

串口调试，负责数据收发，带有串口自选，波特率选择(Serial debugging assistant)

232串口通信实例，简单的模仿USB界面显示，实质做的是一个简单的232串口(232 serial communication)
