HELP establishing dialup in an application

I'm no comm guru, as you'll soon see.  If there's a good RTFM resource, by
all means please point me to it.  If there's a published free application
with source that does all this, I'd love to see it.

I am trying to educate myself on what is involved in automatically
establishing a dialup connection so that we can FTP several files from the
AS/400 to a server once each day - with NO user intervention.  Messages with
"good" or "bad" results could be sent to a special message queue.  Assuming
the configuration is "set", what does my program have to do to vary on (and
in what sequence)?  Should I be checking to see if some other job is using
the same dialup line that my program wants to use?  If I have to vary
something off to vary my ???stuff??? on, then I would want to vary that
something back on after I'm done.

What are "resources", "line descriptions", "controller descriptions", and
"device descriptions" in the dialup communications context?
