Int 21 Fn 4300  - DOS 2+ - Get File Attributes                             [D]

   AX = 4300h
   DS:DX -> ASCIZ filename

Return: CF clear if successful
       CX = file attributes (see AX=4301h)
       AX = CX (DR-DOS 5.0)
   CF set on error
       AX = error code (01h,02h,03h,05h) (see AH=59h)

Notes: under the FlashTek X-32 DOS extender, the filename pointer is in DS:EDX
   under DR-DOS 3.41 and 5.0, attempts to change the subdirectory bit are
     simply ignored without an error
