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.

Word Processor Display Emulation of Data Processor Terminal - Display Screen Updating

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 Fig. 1, hardware is shown from a standard word or text processor which is capable of emulating a data processing display terminal. The data from the data processor or CPU arrives over a communication linkage, referred to as a DCA (Data Contact Architecture) link. The data proceeds through a link adapter which contains a link buffer wherein the received data is temporarily stored. The display adapter interfaces with the link adapter, and the received data is finally transferred to the display refresh buffer where it is displ...
