Abstract

A keyboard emulator system (10) is provided for transmitting simulated keyboard and track ball entries to a control console (100) of a real time data processing system. The simulated keyboard and track ball entries are stored in a script file and sequentially read therefrom, converted to a predetermined format for transmission to the main display controller (130) of control console (100) responsive to a correspondence between a reference time stored in the script file and the current time-of-day provided from a clock subsystem (260). The time-of-day provided by clock subsystem (260) is initialized by a time-of-day value read from the clock subsystem (146) of the control console (100), thereby allowing the simulated keyboard entries to correspond with other data being transmitted to the control console (100) from the main frame computer (102) as part of a test procedure.
