  --------------------------------------------------------------------------

    Subfunction 02 of Function 5Fh returns an entry in the network
    redirection list. The list itself is created via Subfunction 03.

    To call Subfunction 02, place the index value you wish to inspect in
    BX. The local device name will be returned in a 16-byte area pointed
    to by DS:SI, and its network name will be returned in a 128-byte area
    pointed to by ES:DI. BL returns a device-type code (3 for a printer, 4
    for a disk drive), and CX returns a parameter (specified by means of
    Subfunction 03) associated with the device.

    To list all devices on the network, execute this function repeatedly,
    starting with an index (BX) value of 00h, incrementing BX by 1 until
    AX reports an error code of 18.
