DR DOS $IDLE$ - IOCTL - DYNAMIC IDLE DETECTION CONTROL

AX = 4403h
BX = file handle referencing character device $IDLE$
CX = number of bytes to write (0004h)
DS:DX -> $IDLE$ IOCTL structure (see #04113)

Return:
CF clear if successful AX = number of bytes actually written CF set on error AX = error code (01h,05h,06h,0Dh) (see #01680 at AH=59h/BX=0000h)

Notes: When the DR DOS IBMBIO.COM detects the presence of the $IDLE$ device during startup, it will retrieve the address of the idle state data area via INT 21/AX=4458h and pass it along to the $IDLE$ device driver by calling this function.

Format of DR DOS $IDLE$ IOCTL structure: Offset Size Description (Table 04113) 00h DWORD -> idle state data area (see Table !!! at INT 21/AX=4458h)
