• Disable OpenWRT shell on /dev/ttyATH0 serial bridge (on ATMega 32U4 serial name is Serial1)

  • Yun Rev1: Edit file /etc/inittab and add a comment "#" before line ttyATH0::askfirst:/bin/ash --login

  • Yun Rev2: Edit file /etc/inittab and add a comment "#" before line #::askconsole:/usr/libexec/login.sh
