Function 4409h (68-9)    IOCTL: Is Logical Device Remote?             DOS 3.1

Reports whether a block device is associated with a network directory.

On entry:      AH         44h
AL         09h
BL         Drive number (0=default, 1=A, etc.)

Returns:       DX         Bit 12  1           If device is local
Bit 12  0           If device is remote

                                                                          

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.
