Q29467: Mouse EGA Register Interface
Article: Q29467 Product(s): See article Version(s): 6.x 1.00 Operating System(s): MS-DOS Keyword(s): ENDUSER | | mspl13_basic Last Modified: 4-NOV-1988 An application note concerning the Mouse EGA Register Interface can be obtained by contacting the Microsoft Product Support Services Hardware Group at (206) 454-2030. The Microsoft Mouse EGA Register Interface is a library of nine functions. It can be called from assembly language programs or high level languages, such as FORTRAN, Pascal, C, and compiled BASIC. Its functions allow you to do the following: 1. Read and write to one or more of the EGA write-only registers. 2. Define default values for the EGA write-only registers or reset the registers to these default values. 3. Confirm that the EGA Register Interface is present and if so, return its version number. If your program tries to set the EGA registers directly, rather than through the interface, the mouse cursor will draw incorrectly.
