Abstract

A method is described which permits dynamic changing of the devices comprising the real terminal, the characteristics of the real devices, and the default characteristics of the virtual terminals. Some workstations in computer systems have the ability to accept different hardware configurations (monochrome versus color display, mouse versus no mouse); however, changes must be made at the Initial Program Level (IPL). Some workstations allow changes to the real terminal characteristics, but only at IPL time. While this may be acceptable in some environments, requirements can change as a user changes tasks. Therefore, it is desirable to allow not only changes to the real terminal configuration in terms of the devices included, but also in terms of the characteristics of those devices, and other aspects of the real terminal.
