Now... this isn't _exactly_ serial, but the serial that is emulated by the arduino driver in ports. The issue is that running the arduino IDE works (and it boots with the loaded code), but then running 'pronterface' fails to connect --- looking all-the-while like one-way communication. I see someone else basically having the same problem and claiming that hacking a trace (that affects the DTR response) on the arduino fixes it for FreeBSD (see https://plus.google.com/+MiroslavPrymek/posts/6TDdbuoNhzH )... Given this information, can I stty my way out of this problem? Can I make a small modification to pronterface?
