- >>>>>>>>>>>> SPITFIRE FILE TRANSFER TUTORIAL <<<<<<<<<<<<
-
- The "Files Section" of SPITFIRE allows users to transfer files between
- their system and SPITFIRE. Downloading is the process of moving files
- from SPITFIRE to your computer and uploading is moving files from your
- computer to SPITFIRE.
-
- File transfers can be done in a number of ways in SPITFIRE. New error
- checking protocols are being added on a regular basis, but the most common
- transfer method is XMODEM. XMODEM protocol was originally developed by
- Ward Christensen, a pioneer in micro communications. XMODEM is included
- in most communications programs. Before talking any more about specific
- protocols, lets review the general method of locating a file or program
- to download in a SPITFIRE system.
-
- The explanation which follows assumes the SYSOP has adopted the standard
- SPITFIRE FILES MENU and is using the recommended prompts. Since SPITFIRE
- allows the option of changing the wording on each MENU, you may find some
- slight variation of the menu prompts which will perform the same functions.
-
- SPITFIRE allows storing files in different file areas, each of which is
- devoted to different types of files or programs. The status line
- directly above the Files Menu Prompt tells you which File Area is active.
- File areas usually have names like GAMES, UTILITIES, etc., and likewise
- contain that type of files. To list the specific programs available
- IN THE CURRENT FILE AREA, select the "<L>... List Files In This Area" command.
- The complete names of the files will be listed along with file size, file date
- and a short description of each file.
-
- After reviewing the files in the CURRENT FILE AREA, you may change to
- another area using the <C>... Change File Area command. Pressing C
- will bring up a prompt asking which file area you wish to change to. If you
- are familiar with the particular system you are calling you can enter the
- NUMBER corresponding to the area you want. If you don't know the areas
- available you may simply press <ENTER> or carriage return for a complete
- list. After indicating the change you wish to make you may again use the
- <L>... List Files In This Area command to display the files available in
- the new area.
-
- XMODEM FILE TRANSFER
-
- SPITFIRE supports three variations of the XMODEM protocol called XMODEM,
- XMODEM/CRC and 1K-MODEM . One of these three protocols is required if you
- intend to transfer files with extensions of EXE, OBJ, COM, ARC, LBR, etc.
- Files containing the IBM PC special ASCII characters (ones with ASCII values
- above 128) must also be transferred with XMODEM, including Wordstar files.
- These files cannot be transferred in ASCII mode since ASCII transfer is only
- 7 bit and these types of files require the full 8 bit transfer of the data
- with no translation of the contents of the file.
-
- XMODEM also offers the advantage of error checking on a block by block basis
- to assure that the data sent contains no errors. It does this by adding a
- checksum byte to the end of each block of data; the receiver calculates its
- own checksum and compares it to the one received. If an error is detected in
- the transmission, XMODEM will request that SPITFIRE retransmit the block of
- data.
-
- DOWNLOADS ONLY...
- SPITFIRE also supports YMODEM BATCH, YMODEM-g BATCH and SEAlink BATCH for
- downloads but not on uploads. Watch for the one of the next releases of
- SPITFIRE, it will contain these protocols on uploads. The YMODEM-g protocols
- are only available if the system you are calling uses an error checking modem
- and if you are calling with an error checking modem. However, the YMODEM
- BATCH and SEAlink BATCH is available to all callers. YMODEM BATCH and SEAlink
- BATCH allows you to load a Batch Queue with a series of files and then
- perform a continuous download.
-
- To download a file, you will follow the below listed procedure...
-
- 1. Select <D>... Download from the FILES MENU
-
- 2. Select the transfer protocol you want to use by entering the number which
- corresponds to it, (i.e. <3> for XMODEM/CRC.
-
- 3. Enter the COMPLETE file name. SPITFIRE will notify you if the file you
- selected is not available to download.
-
- 4. SPITFIRE will indicate how many blocks and bytes are to be sent and the
- approximate time it will take to download the file. You then have 45
- seconds to start the download.
-
- 5. The file will be transferred automatically block by block under XMODEM
- until the entire file has been sent. You may abnormally abort the
- transfer by sending SPITFIRE an ASCII CAN code (CTRL-X).
-
- 6. Please be certain to select and use matching protocol types for accurate
- data interchange.
-
- FILE UPLOADING
-
- File uploading to SPITFIRE is very similar to downloading.
-
- Before sending a file be sure SPITFIRE has enough disk space to take the file.
- When you select <U>PLOAD at the File menu, the system will tell you
- how much disk space is free on the upload drive.
-
- UPLOAD GROUND RULES
-
- You are encouraged to donate programs to this system. Any type of program or
- document is welcome, however, a few ground rules are in order. The files
- donated must be in the public domain or Shareware. No commercial programs
- should be placed on this system. The SYSOP is not responsible for any of the
- data that is shared on this system.
