实时汉字电子邮件实现方法

A METHOD OF REALIGLING REAL-TIME CHINESE ELECTRONIC MAIL

利用HMPC/XT机异步通信功能,实现实时汉字电子邮件传送方法.汉字邮件直接在屏幕上编辑形成;汉字信息从字符方式下的虚屏缓冲区(VRAM)中读取汉字机内码进行发送;只将一个实时通信联络程序常驻内存,用1CH软中断定时开放通信口,用0CH实行中断接收联络信息.讨论了汉字邮件编辑、传递和实时性等有关技术问题和解决方法.

Ia this paper, we introduce a method for transfering real-time Chinese electronic mail by use of asynchronous communication tunction of IBM PC/XT machine. Its features are Chinese mail is edited and formed on screen directly, The message on screen is sent in corresdonding Chinese machine code read from virtual screen buffser (VRAM) in character mode; For real-time transfer, only the real-time communication connection program is resided in memory, which use 1CH soft interrupt and OCH hard interrupt to open communication port on time and to receive connection message respectively. This paper deals mainly with some technical problems, such as chinest mall edit, transfer aid real-time, etc.
