        Have you tried running it in trace mode, and looking at
the trace log?  Here's what it should show, which is the answer
to your questions about what Lynx is doing w.r.t. binary (a.k.a.,
image) versus text (a.k.a., ASCII) mode:

        ftp URLs accept a type parameter with possible values of A, I, or D.
If you use:

        ftp://www.mindview.net/pub/eckel/solutions.zip;type=I

it would force image mode, but as you can see from the trace, it's using
that mode by default (based on the extension, which is mapped in HTInit.c,
if you do not remap it in a mime.types file  -- not in .lynxrc).  You could
use that for a VM/CMS mainframe if you wanted a text file as raw EBCDIC,
rather that as ASCII.   This is all explained in the online 'h'elp, and
has been for some time, including in the version you are using.
