Soft-Span provides a system for transferring files to and from the system.
Currently, only the XMODEM and XMODEM/CRC protocols are supported.

To upload a file to the BBS, enter UL at the main menu.  You will be prompted:
Name of file>
Enter an appropriate file name for you upload.  If you enterred an invalid
name or if the name already exists in the upload directory, you will have to
enter a different name.  Next, you will be asked for a brief description of
your file.  Enter up to 50 characters as an appropriate summary of the purpose
of the file.  Finally, enter the computer type(s) with which the file will
work.  For text files, you will probably enter ALL or ANY.  Finally, you
will see the following:

Begin file transfer now
^X to abort

Enter your terminal's upload mode or press CTRL-X to abort the file transfer.
Once the upload is complete, you will be credited with file credits that are
a predetermined multiple of the size of your uploaded file.

To download files, you must first select a download directory.  To see a list
of the download directories to which you have access, enter DIR at the main
menu.  Now, select one of those directories by name.  There are several ways
to do this.  For instance, if AMIGA is the name of a directory, the following
commands would select AMIGA as the current directory:

CD AMIGA
GO !AMIGA
GO! AMIGA
!AMIGA

With, CD or GO!, you simply supply the name of the directory.  If you use GO (as
opposed to GO!), you must use the exclamation point to indicate that AMIGA
is a directory and not a message base.  Finally, you can also simply enter
the directory name at the main prompt.  However, you must prefix it by an
exclamation point.  In addition, you need only enter as many letters of the
name that are necessary to identify the base.  For example, the following would
also work:

CD AMI
!AM

Once a directory is selected, use the LIST command to see the available files.
If you enter LIST by itself you will be asked to enter a search pattern or
'#' for new files.  If you want a complete list, just hit return here.  You 
can also enter a pattern of letters to search.  If you choose a search pattern,
only the files whose names contain those letters will be displayed.  Choosing
the '#' option will cause only new files since your last call to be displayed.
All of these options can be chosen directly from the main menu.  Enterring
LIST <PATTERN> will search for the pattern specified.  LIST -A or LIST *
will list all files, and LIST -N or LIST # will cause only new files to be
displayed.

Once you have picked out a file to download, enter DL.  You will be prompted
to enter the name of the file you wish to download.  You can also specify
the file name on the command line:  DL <FILENAME>
In addition, you will need to have enough file credits to cover the size of
the file you wish to download.  You can obtain these credits by uploading
to the BBS.  Once you have downloaded the file, you will be debitted for the
appropriate number of download credits.
