Modifying Optiboot to Upload Sketches over RS485

I hope you understand it...

Good luck.

Great!! It works for me too! I probably never would have thought to do it this way. Or maybe after a few weeks researching. I really thank you for your help. Now I will work in some scripts for automate the process of sending the "reset" command before uploading the sketch, to one or to a set of devices.

Thank you!
