RS485

一个十分好的用汇编和C写的异步串口程序-with a very good compilation and writing of the C asynchronous serial procedures

Windows 2000 环境下直接访问串口、并口的小程序，包括VC、delphi源码-under Windows 2000 directly to the serial port, parallel port of small programs, including the VC, Delphi source

C8051F340 uart1简单程序 实现串口1的数据收发-C8051F340 uart1 11111111111111111

通讯软件 Rs232 数据采集 Sql2000数据库-Communication software Sql2000 database Rs232 Data Acquisition

串口操作源程序，可以对串口读写操作，当然也可以自发自收，是一个联系串口通信的好例子-source can write to serial port, of course, can also spontaneously collected, the serial link is a good example of communication

一个迷你的com通讯程序，是用win32asm写的。功能全面-a program made by win32asm

这是本人在网上下载的关于深入浅出VC++串口编程之基于Win32 API的教程-This is my downloading on the plain language VC++ Serial programming based on the Win32 API tutorial

串口控制程序一般分为查询和中断两者方式。查询方式适用于简单的应用，简单可靠，但是缺点是需要占用处理器资源，在发送或者接收数据的时候不能做其它的事情，处理器利用率低。中断方式下，在发送或者接受数据的时候处理器还可以做其它的工作，效率较高。-Serial control procedures will generally be divided into two way query and interruption. Query applied to simple applications, simple and reliable, but the drawback is the need to occupy processor resources to send or receive data at the time should not make other things, the processor utilization rate. Interrupt mode, the send or accept data when the processor can do other work, more efficient.

在LPC2106上实现并测试过的代码,用串口收到的数据回显到串口(通过环行缓存实现)并将串口发送的接口写成了printf的形式 -To achieve the LPC2106 and tested code, serial data received echo to the serial port (via the ring buffer to achieve) and serial interface to send written in the form of a printf

多串口调试，可以在同一个机子上连接，也可以用RS-232连接到两个机子上测试串口通讯，-Multiport Serial debugging, you can connect with a machine, can also use RS-232 connected to the two machine test serial communications,
