串行口是计算机一种常用的接口，具有连接线少，通讯简单，得到广泛的使用。常用的串口是RS-232-C接口(又称EIA RS-232-C)它是在1970年由美国电子工业协会(EIA)联合贝尔系统、调制解调器厂家及计算机终端生产厂家共同制定的用于串行通讯的标准。它的全名是"数据终端设备(DTE)和数据通讯设备(DCE)之间串行二进制数据交换接口技术标准"该标准规定采用一个25个脚的DB25连接器，对连接器的每个引脚的信号内容加以规定，还对各种信号的电平加以规定。传输距离在码元畸变小于4%的情况下，传输电缆长度应为50英尺。 　　Linux操作系统从一开始就对串行口提供了很好的支持，本文就Linux下的串行口通讯编程进行简单的介绍.-computer serial port is a common interface, with connecting lines, simple communications, to be widely used. It is commonly used serial RS-232-C interface (also known as the EIA RS-232-C) it is in 1970 by the American Electronics Industry Association (EIA) Joint Bell System, a modem manufacturers and computer terminal manufacturers developed for serial communication standards. Its full title is "data terminal equipment (DTE) and data communications equipment (DCE) between serial binary data exchange interface technology standards," the use of a standard 25 feet to the DB25 connector, the connector pin of each signal content requirements, but also the right signal--

Atmel Mega16上调试通过的，可以同时发送一个字符串，并产生中断-on the debugging, it will also send a string, and have interrupted

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.

串口的监控程序,提供了固定命令模式和，用户自定义模式。-serial monitoring procedures, and providing a fixed command pattern and user-defined mode.

用于串口应用程序的调试监控工具，软件可模拟设备往串口发送指定格式的数据串，同时也可以用于实时监控串口读写过程中的所有数据流。☆ 自动侦测当前系统中所有可用的串口数，支持USB扩展出的虚拟串口（可到COM256）。☆ 支持ASCII码和十六进制数据格式的发送和接收。☆ 可以自由选择侦测的串口，接收数据区的容量可以无限大。☆ 发送、接收数据区的大小可以随意拉伸调节。☆ 对发送、接收数据区加入鼠标右键菜单的支持。☆ 扩大串口波特率的支持，现最高Baud可到921600。☆ 支持Unicode内码显示。☆ 增加自动发送数据功能。☆ 增加保存显示记录的功能。-applications for serial monitoring of debugging tools, software can simulate serial devices to send data to the specified format string, but also can be used for real-time monitoring serial process of reading and writing all data stream. automatically detect the current system all available serial number, support USB expansion of Virtual Serial Port (available to COM256). support ASCII and hexadecimal format of the data to send and receive. freedom of choice to detect the serial and receive data in large capacity can be unlimited. send and receive data of arbitrary size can adjust tension. right to send and receive data by adding areas of the right mouse button menu support. serial port baud rate of expansion, is

串行接口通讯试验该试验可以学习如何编写一个通讯程序。这个试验能够实现的功能很简单，仅仅作为试验用。工作环境为：无需其余任何环境，直接接通电源即可。-serial communication interface test of the pilot can learn how to prepare a communication process. The pilot function can be achieved is very simple, just to experiment with. The working environment : the environment without any rest, can be directly connected to power.
