Subject: [PATCH] Added just enough for a complete manual test of writing to a
 .ADF with the 1770 then getting the correct result parsing it back on the
 host side in order potentially to update a file.

... which means that now it's time to worry about when and how mounted files should actually update themselves. Which will make for some fun with threading, I dare say.
