Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

#define INCL_DOSDEVIOCTL
 
USHORT DosDevIOCtl(0L, pbInputMode, 0x0051, 0x0004, hDevice)

The KBD_SETINPUTMODE function sets the input and shift-report modes for the
keyboard device driver. The input mode defines whether the following input
keys are processed as keystrokes or as commands: CTRL+C, CTRL+BREAK, CTRL+S,
CTRL+P, SCROLL LOCK, PRTSC.
 
The shift-report mode defines whether the shift keys are processed as shift
keys or as keystrokes.
 
Parameter    Description
────────────────────────────────────────────────────────────────────────────
 
pbInputMode  Points to the variable that contains the input mode for the
             keyboard. If the variable is ASCII_MODE, the input mode is
             ASCII. If the variable is BINARY_MODE, the input mode is
             binary. If these values are combined with SHIFT_REPORT_MODE,
             the function enables the shift-report mode; otherwise, the
             shift-report mode is disabled.
 
hDevice      Identifies the keyboard that receives the device-control
             function. The handle must have been created previously by using
             the DosOpen function.
 
Return Value
 
The return value is zero if the function is successful or an error value if
an error occurs.
 
Comments
 
The default input mode is ASCII. The keyboard device driver maintains an
input mode for each screen group.
