I would like to disable the serial console and boot up messages while still being able to write to the port.
I have tried disabling the port in raspi-config. This disables the console and the kernel messages but also removes /dev/ttyAMA0, which my code is writing to.
In my application, I am writing to the port using Node and the SerialPort npm package.
I'm using a Raspberry Pi 2 Model B, and the 2016-05-27 version of Raspian Jessie.
