user40640: I tried preventing my Arduino Mega 2560 from restarting every time I open the serial monitor. This link didn't work for me at all.
I tried connecting the RESET pin to 3.3v pin via a 60 ohm resistor and it worked for me. The question is: If I leave that resistor permanently connected, will this solution damage my board as time passes?

user63556: A 22uF cap between reset and ground does work on my Mega 2560 - opening the serial monitor will not restart the program. However, the Mega is then not downloadable. Therefore, I grounded the cap thru a normally closed relay and connected its control to a digital output. I normally operate with the relay closed. When I want to download a new program I open the relay first. It works great :-)
