<Reference> File transfer procedures
(1) File transfer by Fcopy.EXE
For file transfer by Fcopy, put Fcopy.exe and the files in a same
directory, and boot the MS-DOS. Go to the directory of the files,
and type "Fcopy file name" and transfer is made. In the following
case, the SFU file is in the C:\ROM directory and it is transferred.
(2) File transfer by File2PRN.EXE
For file transfer by File2PRN, the machine to which the files are
transferred must be set as a printer. The connection types as a
printer are parallel port, network, and USB. For transfer by the net-
work connection, IP address setting is required. It is not described
here. For transfer of the files, execute File2PRN.EXE, and the fol-
lowing window is displayed.
