Networked IBM 3270 emulation on a microcomputer

Abstract

This paper discusses the implementation of an emulation of an enhanced interactive terminal, a variant of an IBM 3270, based upon the Acorn BBC microcomputer. It also describes the environment within which this development took place. The emulation uses a standard asynchronous connection to a packet assembler-disassembler. The 3270 data stream is carried via X.29 and X.25 protocols to IBM MVS and VM systems. The paper concludes with a discussion of the advisability of implementation of a manufacturer's protocol at the present stage of development of national and international standards.
