Downgraded my kernel.

Looking here I did these commands:
I picked the
*Ubuntu, with Linux 4.4.0-2-upboard (upstart)
In the Grub boot Advanced options. Looked like this on the serial port.
So it like down graded. But I guess it's a better kernel for this Up2 board.

Use the and keys to select which entry is highlighted.
Press enter to boot the selected OS, `e' to edit the commands
before booting or `c' for a command-line. ESC to return previous
menu.
So it like down graded. But I guess it's a better kernel for this Up2 board.

I thought doing this I could then get the serial port to work right.
But still I can only receive not send any data.
