Personal computer/host emulation system for handling host data with personal computer application programs at personal computers
First Claim
1. In a computing system including a host computer, a personal computer having a display and a keyboard and containing a terminate and stray resident application program which processes data in a first format resident in said personal computer, and a PC/host terminal emulation program means resident in said personal computer and communicating with said host computer which processes data in a second format, said computing system further comprising:
- a. screen data conversion means within said personal computer coupled to said PC/host terminal emulation program means for constructing a display screen for said data processed by said host computer in said second format;
b. A keystroke interpretation routine resident within said personal computer for distinguishing between personal computer commands and host computer commands entered from said keyboard;
c. means coupled to said keystroke interpretation routine and responsive to said identified personal computer commands to said terminate and stay resident application program for processing in said first format; and
,d. means coupled to said keystroke interpretation routine for passing host computer commands representing changes to said screen data to said host computer via said PC/host terminal emulation program means for processing in said second format.

Abstract
A system for emulating the operation of a terminal connected to a host computing system while retaining the ability to utilize personal computer application programs resident in the personal computer by utilizing a personal computer/host terminal emulation program which conducts an analysis of host data and keystrokes to identify personal computer commands and calls the appropriate resident application program in response to such commands.
