You're welcome.  I'm surprised that this problem was causing you
problems.  I had assumed that it was an unlikely boundary condition.  It
was found by one of our engineers who was investigating \r\n handling in
newlib.  He diagnosed the problem from looking at the code, which is
always impressive.

It's possible that this is due to some of the changes I've been making
to tty/console handling, also.

Dunno.  DJ can you tell Glenn where you got "more"?

Let us know and we'll put it on our "ported software" web page.
