DOS Fn 440aH: IOCTL Is File/Device Remote

                                                         Compatibility: 3.1+ 
 Expects: AX    440AH
          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).
