There are also some hardware kludges that involving adding a cap or resistor (depends on which board you have) that can disable the auto-reset in hardware.

Google around for  Arduino disable auto reset, and you will find information on how to do it.


Cutting the "reset-en" trace is probably the simplest (and reversible) way of disabling auto-reset. I'm not sure when this was introduced, but the current Uno and Mega both have this (nice) feature.

But to go back, it requires soldering again.
The chipkit solution is better. It has a 2 holes for a header with a trace between them. Cut the trace and solder
in a 2 pin male header. Now you can use a jumper to enable/disable auto-reset without any soldering.

The Seeeduino AVR based board includes an actual switch which is even better since it requires no
hardware modifications.
