Arduino on Xcode Project — Official Thread

Hey Olivier,

try this in your makefile for opening a serial terminal from XCode:

serial: 
	@echo " ---- open serial ---- "
	osascript -e 'tell application "Terminal" to do script "screen /dev/tty.usbmodem* 9600"'
	
killserial:
	@echo " ---- close serial ---- "
	osascript -e 'tell application "Terminal" to do script "screen -X quit"'

You can then add these rules after and before your upload if you want.
