Int 21H, AH=5FH, AL=03H

3.1 and higher

REDIRECT DEVICE

  AX = 5F03h
  BL = device type
    03h printer
    04h disk drive
  CX = user data to save
    0000h for LANtastic
    4E57h ("NW") for NetWare 4.0 requester
  DS:SI -> ASCIZ local device name (16 bytes max)
  ES:DI -> ASCIZ network name + ASCIZ password (128 bytes max total)

CF clear if successful
CF set on error
AX = error code (01h,03h,05h,08h,0Fh,12h) (see #01680 at AH=59h)

If device type is disk drive, DS:SI must point at either a null string or a string consisting the drive letter followed by a colon; if a null string, the network attempts to access the destination without redirecting a local drive. The DOS kernel calls INT 2F/AX=111Eh with AX on top of the stack. Also supported by Banyan VINES, LANtastic, and 10NET

AX=[[en:docs:dos:api:int21:5f:02|5F02h]] - AX=[[en:docs:dos:api:int21:5f:04|5F04h]] - INT 2F/AX=111Eh - INT 60/
