INT 21 - DOS 3.1+ network - GET REDIRECTION LIST ENTRY
        AX = 5F02h
        BX = zero-based redirection list index
        CX = 0000h (LANtastic)
        DS:SI -> 16-byte buffer for ASCIZ local device name
        ES:DI -> 128-byte buffer for ASCIZ network name
Return: CF clear if successful
            BH = device status
                00h valid
                01h invalid
            BL = device type
                03h printer
                04h disk drive
            CX = user data previously set with AX=5F03h
            DS:SI and ES:DI buffers filled
            DX,BP destroyed
        CF set on error
            AX = error code (01h,12h) (see AH=59h)
Notes:  this function is passed through to INT 2F/AX=111Eh by the DOS kernel
        error code 12h is returned if BX is greater than the size of the list
        also supported by Banyan VINES, PC-NFS, LANtastic, and 10NET
