C-Xenix多用户汉字操作系统的设计与实现

THE DESIGN AND IMPLEMENTATION of C-XENIX MULTI-USER CHINESE OPERATING SYSTEM

UNIX从AT&T的实验室走向社会,正逐渐成为计算机基本系统软件的国际标准和工业标准,Xenix系统是在IBM PC/AT等286机器上运行的一种UNIX商业化版本。本文讨论基于Xenix的汉字信息处理系统C-Xenix的设计与实现。本文首先对Xenix系统及开发汉字系统的几种方案作了简单介绍,然后给出了C-Xenix的设计目标和实现方案。本文提出了一种新的开发Xenix(UNIX)汉字系统的方法。即用Xenix(UNIX)系统本身提供的软件开发系统来开发汉字系统,这种方法较之传统的开发方法有着明显的优越性。本文的重点就是讨论这种方法在改造主控台及西文打印机时的实现途径及实现细节。

UNIX, as it goes from the laboratory to the public, will become the international and industry standard of basic computer system software. Xenix is a business version of UNIX, which runs on the IBM/PC AT and other 286 based microcomputers. This paper will discuss the design and implementation of the Xenix-based C-Xenix system. @ In this paper, a brief introduction to the Xcnix system and the methods of developing a Chinese system is given at first, then the goal and scheme of developing C-Xenix are proposed. A new method of developing C-Xenix (C-UNIX) system is presented in this paper. The main idea of this method is to use the Softweare Development System which is given by the Xenix (UNIX) itself to develop the Chinese system. This method is obviously better than others. The focus of this paper is on using this method to make the console and printer process Chinese information.
