The DL command is used to download files from the system.  Before downloading,
you must select a download directory via the CD command.  Next, choose a
file by name from the list of available files.  You can get such a listing
through the LIST command.  Once you have selected a directory and a file,
enter DL at the main menu.  You will be asked for the name of the file you
wish to download.  If it is found and you have sufficient download credits,
you will be asked whether you wish to continue.  Hit Y for Yes and enter your
terminal's download mode.  You can abort the transfer by hitting CTRL-X.  In
addition, note that you must have selected a file transfer protocol in your
terminal configuration. 

As an optional shortcut, you can enter your command in the format:
DL <filename>
Where <filename> is the name of the file you want to download.
