Is was the same with all RAM-Filesystem Options. The character loss problem
has been resolved thanks to Robin. I've posted the success message
yesterday, but it didn't seem to have arrived at the list, so I'll re-post.

What remains is that I can't access RAM-Filesystem and Serial line by
threads with (blocking) highlevel C-Library input functions. Seems a
general problem.

For a workaround, I now read the serial line by lowlevel cyg_io_read() calls.

Thanks, Peter
