I don't know of any FTP for a RSTS/E (or RSTS) machine, but
there are several commercial and one freeware package for real
RT-11 internet connectivity. See


for information on the freeware package.

Good question! If there's some way that you can do a "file to
device" copy under RSTS/E, then you'll be able to copy the .DSK
to a real disk and then mount that as a RT-11 volume. I've never
done this on RSTS/E, but if you ask where all the experts
hang out (comp.os.rsts) you'll probably get a good answer.

Note that I've written several tools for manipulating RT-11
.DSK files on "foreign" systems, and many classic Unices
shipped with similar tools. The RT-11 filesystem is simple
enough that such tools are easy to write. See


for a tool that I've suggested in the past when folks have asked
"how can I read a .DSK without a real RT-11 system?"
