getty on the serial line
It can be useful to have a tty on the serial line, e.g. if USB networking doesn't work and you still want to access the shell on a running system.
This can be achieved by enabling getty on the serial line. To achieve this, add
ttyHSL0::respawn:/sbin/getty -L ttyHSL0 115200 vt100 (adjust for the serial on your device) to the file
When the device is finished booting you will get a login prompt on the serial line.
