[Coco] [CoCo] Just learning OS-9 - Questions

Aaron,
Does RFM actually work? Or is it still under developement?
If it works, what would be the proper way to use it?

There has been some work done towards this type of thing already.
It's actually a new file manager called RFM (Remote File Manager).  It
allows you to mount a directory on the server or even a remote FTP
server or SMB share under NitrOS9.

Making this work for rawcopy would probably not be too difficult,
actually easier than making it work with dir, copy, and the other
utilities in OS9 (because those often assume an RBF device).  I'll see
what I can do.
