_______________________________________________________
Details:
It came to my attention that I could only upload every 2nd try to my
bootloaded AVR chip (or 'Arduino' if you like). The first pass would fail and
I would abort avrdude (the chip was _not_ reset). With the old code this left
the DTR line in a usable state for the next run, which then succeeded
reproducibly.
This patch reverses the sequence of setting/clearing DTR/RTS. In depth
explanation including a small schematic are in the comment in the .diff file.
