Abstract

In the present-day 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 word 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 word processing capability into an overall office systems environment, the field is advancing in the direction of utilizing the display terminal associated with the word processing system as an output terminal for the host data processor.

Emulation of Data Processing Displays - Reset Commands

In the present-day 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 word 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 word processing capability into an overall office systems environment, the field is advancing in the direction of utilizing the display terminal associated with the word processing system as an output terminal for the host data processor. In such a system, interactive capability is provided for switching from a word processing session to a data processing session wherein the word processor emulates a data processing display terminal. The present apparatus provides an interface between the control unit for the host processor and the word processing system. This is accomplished through the expedient of an adapter card in the word processing system. This adapter card's memory must interface with the host controller as well as the input/output circuitry of the word processor. The present expedient relates to a particular situation wherein the controller for the host processor issues a reset command to the word processing system. Under such circumstances, the only valid response from the word processor syste...
