For serial communication with an Arduino I wanted an Arduino IDE like serial monitor in the Raspberry Pi shell. Since I could not a find a terminal that did support “line mode” I found another workaround.
'''Don't forget the levelshifter when your Arduino runs on 5V!!!'''
Reboot the system.

Then I run the serial.sh script (you need all three for this to work)

This one i basicaly copy and pasted it, without understanding it. It gets the serial interface in the right mode to talk to an Arduino (with 115200 baud)
to listen to the serial port.
Unfortunately there are some unwanted characters at the end of a line. I’m not sure why, but I just replaced them with a space. (That way they just do not any me anymore)
To get data to the Serial port I use:
<pre>echo "$a" > /dev/ttyAMA0</pre>
I use tmux split screen to be able to see both at the same time.
All of this is probably not a clean or nice solution, but it does what I wanted it to do.
