Abstract

In DisplayWrite 2 for the IBM Personal Computer, the keyboard software is matched to a given menu-language; e.g., a French menu-language DisplayWrite 2 runs only on a French PC keyboard. This match-up is used for the U.S.A., U.K., France, Italy, Spain and Germany. This means that a given copy of DisplayWrite 2 is designed to use only one of the six PC keyboards for the six countries listed. An enhanced version of DOS 2.1 supports a DOS command that "switches" PC keyboards. Of course, the physical keyboard is not switched; rather, the RAM BIOS is switched so that another PC keyboard is emulated. This new DOS command allows 10 different keyboards to be emulated. The U.S.A. keyboard is available via a "hot key" CTL-ALT-F1 key sequence. The emulated keyboard can be returned to via a "hot key" CTL- ALT-F2 key sequence.
