scp is a lovely piece of high-tech: it does a cat of the file, sticks it
into the ssh pipe, and redirects it to a file again on the other end.
That's pretty much it ;-)

You could do the same over a clean Telnet link. Since TCP/IP is
error-free on that level (lower layers take care of transmission
errors), a real file transfer protocol like Zmodem is not essential. But
rz/sz are still part of *nix distros, and moderately easy to use even
though they contain some serious design flaws.


Regards,
Arjen.
