  --------------------------------------------------------------------------
 
    This subfunction (DOS 3.1 and later only) allows you to determine
    whether a block device (specified in BL with default=0, A=1, etc.) is
    associated with a network directory. For local devices, DX returns the
    attribute word from the device header; for remote devices, DX returns
    with bit 12 set.
