Int 17 Fn 83  - Alloy Ntnx, Mw386 - Set Number Of Copies                   [N]

   AH = 83h
   AL = mode
       00h NTNX compatibility
       CL = number of copies (max 99, default 1)
       02h MW386 v2+
       BX = logical device number
           00h-03h = LPT1-LPT4
           04h-07h = COM1-COM4
       CX = number of copies

Return: AL = status (see #0566)

Note:  in NTNX compatibility mode, this function only affects LPT1
