Study of Data Communication with Computer——Design of Data Transfer Socket

数据通信是现代通信的主要方式．研究数据通信对把握通信的发展方向有重要作用．论文中对数据通信的概念及相关的协议标准进行了讨论,并利用ＩＳＡ插槽,使用Ｉｎｔｅｌ公司的８２５５Ａ及８２５１Ａ实现并行通信及串行通信．外部遵循ＲＳ－２３２－Ｃ及ＩＥＥＥ－４８８标准,只要遵循同一协议就可互连．

The concept of data communication and its protocol related are discussed. A data transfer socket is designed based on ISA bus using Intel 8255A and 8251A to establish parallel and serial data transfer. The socket can be used by any computer that comply with IEEE-488 or RS-232-C protocol.
