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--

串口通讯在客户端/服务器类型的应用程序设计中经常要使用到,目前串口通讯采用的一般是专用软件包或者标准串口通讯协议(如XMODEM、ZMODEM等),这样完整详细且免费的软件包比较少,所以在SPCOMM的基础之上建立了本文所描述的串口通讯协议,称之为RCC(表示为Reliable Comm Communication),其主要目标是在用串口进行通讯的客户端/服务器双方建立一条可靠的通讯链路,就象TCP(RFC793)一样。该协议的目前的开发是采用VC++,应用平台为WIN95/NT,但作为RCC协议的本身不受具体编程语言及操作系统所限制-Serial port communication in client/server type of application design often use to the current serial communication is generally used in special packages or a standard serial communication protocols (such as XMODEM, ZMODEM, etc.), such a complete package details and free more less so on the basis of established SPCOMM described in this article serial communication protocol, called RCC (expressed as a Reliable Comm Communication), whose main objective is to communicate with the serial port client/server sides to establish a reliable communication link, like TCP (RFC793) the same. The current development of the protocol is used VC++, application platform for WIN95/NT, but as the agreement itself, RCC concrete programming

自己使用VB编写的串口通信程序,1号和2号。将两个COM口用串口线连接,就可以运行这两个程序了。实现的功能:1号程序随机发送两个数字,2号程序接收并进行计算,然后发回1号机,1号机接收并显示出来。-its own use VB prepared by the serial communication program, 1 and 2. The two COM ports with serial line connectivity, it can run on the two proceedings. The functions : 1 random procedure to send two figures, the No. 2 receiver and procedures for calculating and then sent back No. 1, No. 1 receiver and displayed.

串口通信程序,通过汇编语言使用BIOS的。
本串行通信程序利用汇编语言通过BIOS中断调用和DOS功能调用实现PC机双机串行通信。其中,上位机和下位机串行口均为辅串口COM2(口地址为2FXH),对外用9针连接器与令一台PC机连接;BIOS通过“INT 14H”4个中断服务子程序,分别完成串口初始化编程、发送一帧数据、接受一帧数据以及测试通信线状态。本程序分为PC机串口自动测试程序(目的是测试串口好坏)和PC机全双工双机通信程序两个部分。-the serial communications procedures through the use of assembly language BIOS interrupt calls and function calls DOS PC Dual Serial Communication. Among them, PC and the next crew will be supplemented by serial port Serial COM2 (I address 2FXH) external with 9-pin connectors and enable a PC connection; through the BIOS "INT 14H," four interrupt service routines, complete serial port initialization programming, Send a data receiving a data communications test and the state line. The procedures are divided into PC serial automatic test procedure (for the purpose of testing Serial good or bad) and full-duplex PC-machine communication program two parts.
