串并口编程，可以直接控制端口

AVR单片机串口异步通信,通过电脑串口助手使电脑和单片机运行简单的数据通讯-AVR microcontroller tramsmition

串口通信控制XX变频器,VB下编的界面，已调试通过，可以运行，-VB_rs232_transducer

自己做串口通讯介绍（VC平台） 一个很vc上的-done on serial communication (VC) is one of the Eastern vc

MSComm控件资料,Visual Basic 6.0(以下简称VB) 是一种功能强大、简单易学的程序设计语言。它不但保留了原先Basic语言的全部功能，而且还增加了面向对象程序设计功能。它不仅可以方便快捷地编制适用于数据处理、多媒体等方面的程序，而且利用ActiveX控件MSComm还能十分方便地开发出使用计算机串口的计算机通信程序。本文结合计算机通信的两个例子，详细介绍如何在VB中使用MSComm控件。 处理方式 -MSComm information, Visual Basic 6.0 (VB hereinafter) is a powerful, relatively simple programming language. It not only retains the original Basic language functionality, but also an increase of object-oriented programming design functions. It will not only facilitate the efficient preparation of the application to data processing, multimedia and other aspects of the procedure, and the use of MSComm ActiveX control can be very convenient to use the computer to develop the computer serial port Communication Program. Based on computer communication, the two examples in detail how to use VB MSComm. Approach

串口编程调试精灵 希望对各位有用-hope that the Wizard useful to you!

moxa 公司出的串口库，带开发源码，非常方便的串口开发工具-The serial moxa company database, with the development of source code, the serial port is very convenient development tools

用于实现上位机与下位机通信功能。用于串口通信。-For implementation with the lower PC communication function. For serial communication.

实现了一个简洁易用的多线程串行通讯接口,可以切换查询和自动接收模式,进行对串口数据收发 -Realize a simple and easy-to-use multi-threaded serial communication interface, you can switch query and automatically receive mode and proceed to the serial data transceiver

常见的串口通信程序，用过使用C#语言，利用控件实现串口的实时通信-common serial communication program, used to use C# language, the use of controls to achieve the real-time serial communications

将串口通讯协议存储为一个通讯文件，可是随时将存储通讯协议文件调入计算机运行与下位机通讯可以实现通讯对话，-Serial communication protocol will be stored as a communications document, but to keep the communication protocol storage document transferred to the computer is running and the next-bit machine communication can realize communication dialogue
