On reset or powerup, ehe Optiboot or other bootloader code is run. If an external reset was the cause, listening mode is entered, and the LED is flashed. Programming commands in STK500 protocol are listened for, of the serial line at 115200 speed. If none are received in a small timeout window (~ 1s), the normal code is executed.
The DTR line if used to trigger a reset in software IDE (see here.
