Int 21 Fn 4403  U - Qualitas 386max V6.01+ - Set State                     [m]

   AX = 4403h subfn 03h
   BX = handle for device "386MAX$$"
   CX = number of bytes to copy (up to size of state buffer)
   DS:DX -> BYTE 03h followed by state buffer
         (see #1154 at AX=4402h"386MAX")

Return: CF clear if successful
       AX = number of bytes actually written
   CF set on error
       AX = error code (01h,05h,06h,0Dh) (see #1366 at AH=59h/BX=0000h)

Note:  the first byte of the buffer must be either 01h, 02h, or 03h
     (specifying the version of the state record) and the buffer must
     contain CX bytes AFTER the initial byte
