-**Serial modification** 
----- 
  
-For using the serial line of the Raspberry Pi you have to make some small modifications (just if you hadn't run the alamode setup): 
- 
-In the file: /​boot/​cmdline.txt\\ 
-change:\\ 
-''​dwc_otg.lpm_enable=0 console=ttyAMA0,​11520 kgdboc=ttyAMA0,​115200 console=tty1 root=/​dev/​mmcblk0p2 rootfstype=ext4 rootwait''​\\ 
-to:\\ 
-''​dwc_otg.lpm_enable=0 console=tty1 root=/​dev/​mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait''​ 
- 
-And in the file: /​etc/​inittab\\ 
-comment out:\\ 
-''​2:​23:​respawn:/​sbin/​getty -L ttyAMA0 115200 vt100''​\\ 
-to: \\ 
-''#​2:​23:​respawn:/​sbin/​getty -L ttyAMA0 115200 vt100''​\\ 
- 
-Because the Arduino IDE is not able to find the tty connection of the serial port (ttyAMA0) you have to mirror it to ttyS0. That is to be done with a file in: /​etc/​udev/​rules.d\\ 
-then name it (the number is according to the order in which the rules were loaded):\\ 
-''​85-paperduinopi.rules''​\\ 
-and put in the following line:\\ 
-''​KERNEL=="​ttyAMA0",​ SYMLINK+="​ttyS0",​GROUP="​dialout",​MODE:​=0666''​
