BX    file handle  (device or disk file)
                                                                  
Returns: AX    error code  if CF is set to CY
DX    IoctlHandleInfoRec (Bit 15 is 1 if file/device is remote)
                                                                  
Info: Obtains information about a file or device represented by a
file handle, including whether or not it is local (on this
computer) or remote (on a network server).  It also tells whether
the handle represents a file or a device.

On return, DX bit 15 (DX & 8000H) is 1 if the file or device is
remote (i.e., on a network server).  See IoctlHandleInfoRec for a
full layout of the rest of the returned information.

Notes:   In general, you should treat local and remote files the same.
One exception might be if you want to avoid overwriting
configuration files when they are shared on the network.

  If the network is not started, CF is set and AX contains and
error code of 0001H (invalid function).
