TAR> I suspect that your firmware supports automatic address increment. The
TAR> firmware I used didn't so I had no idea how to handle it.

Yes, the comments at the beginning of the file indicate that too, but
I can't really prove it as assembler is not my "favorite language". :(

TAR> Without auto incr, avrdude sends 3 extra bytes (cmd + hi + lo bytes).

OK, sounds like a starting point. But can that really triple the
programming time?

TAR> Could you send me a 2.3 firmware if you have it? I didn't have any
TAR> luck with google.
