Int 2F Fn 111E  CU - Network Redirector - Do Redirection                   [N]

   AX = 111Eh
   SS = DOS DS
   STACK: WORD function to execute
       5F00h  get redirection mode
           BL = type (03h printer, 04h disk)

           Return: BH = state (00h off, 01h on)
       5F01h  set redirection mode

           DS:SI -> 16-byte local device name buffer
           ES:DI -> 128-byte network name buffer

           Return: must set user's BX to device type and CX to
               stored parameter value, using AX=1218h to get
               stack frame address
       5F03h  redirect device
           BL = device type (see INT 21/AX=5F03h)
           CX = stored parameter value
           DS:SI -> ASCIZ source device name
           ES:DI -> destination ASCIZ network path + ASCIZ passwd
       5F04h  cancel redirection
           DS:SI -> ASCIZ device name or network path
       5F05h  get redirection list extended entry
           BX = redirection list index
           DS:SI -> buffer for ASCIZ source device name
           ES:DI -> buffer for destination ASCIZ network path

           Return: BH = status flag
               BL = type (03h printer, 04h disk)
               CX = stored parameter value
               BP = NETBIOS local session number
       5F06h  similar to 5F05h???

Return: CF set on error
       AX = error code (see #1366 at INT 21/AH=59h/BX=0000h)
   STACK unchanged

Notes: this function is called by the DOS 3.1+ kernel on INT 21/AH=5Fh
     (including LAN Manager calls)
   the PC Network 1.00 redirector does not support function 5F06h
