kbd_fix
Command

Purpose: Installs new keyboard interrupt routines that operate with a 159
character buffer rather than PC-DOS's normal 15 character buffer.
Format: kbd_fix
(Usually done once per startup, in autoexec.bat file)
Type: External
Remarks: The Ultimate source of information for this command is John
Socha's article in the November 1983 Softtalk, p. 117.
John includes an assembly language listing of these routines. A summation
of the article: DOS (all versions, it's built into ROM BIOS) includes
a 15 character buffer for keyboard input. Giving DOS the kbd_fix
command installs new keyboard interrupt handlers that use a 159 character
buffer. In addition, these new interrupt routines recognize one special
keyboard command: pressing control-alt clears the keyboard buffer.
Kbd_fix will attach itself to DOS and use about 700 bytes of memory.
