Abstract

In the present-day text or word processing environment, the operator often requires access to a host data processor through a low cost data link for data processing and records capability. An original solution to this problem was to utilize both a text processor and a separate data display terminal, such as the IBM 3278, which was compatible with the data processor. However, with the integration of data processing and text processing capability into an overall office systems environment, the field is advancing in the direction of utilizing the display terminal associated with the text processing system as an output terminal for the host data processor.

Emulation of Data Processor Display Terminal by Word Processing System - Memory Sharing

In the present-day text or word processing environment, the operator often requires access to a host data processor through a low cost data link for data processing and records capability. An original solution to this problem was to utilize both a text processor and a separate data display terminal, such as the IBM 3278, which was compatible with the data processor. However, with the integration of data processing and text processing capability into an overall office systems environment, the field is advancing in the direction of utilizing the display terminal associated with the text processing system as an output terminal for the host data processor. In such a system, operator interactive capability is provided for switching from a text processing session to a data processing session wherein the text processor emulates a data processing display terminal. In such an emulation on the word processor, it is customary for the word processor to be linked to a port in a control and multiplexing unit for the host data processor. Because of the increased processing power of a word processor, it has been found that a single word processor may emulate a pair of data processing terminals which are connected to a pair of respective ports in the controller and multiplexing unit. Where the word processor thus emulates a pair of data processing display terminals, it is customary for it to have an adapter card or hardware to provide the interface between the word processing system an...
