What follows is a transaction with net.bio.net in which I log on by ftp as 'anonymous' and then view directories, change directories, GET a file (which is sent to my Liberty home directory), and exit from ftp. If I had wanted to move UP a level in the directory I would have issued the command cd .. --change directory upwards.
