Arduino IDE - RTS or DTR ? (Mac)
Which serial pins are used for Arduino's reset line ?
Both. :)
YELLOW = DTR
GREEN = RTS
(RED = TX)
Note: Technically speaking, DTR is the primary reset pin.
RTS seems to have been kept for legacy purposes, though.

Also be careful with Serial Monitor;
It triggers both pins, as well.
