Serial console not working for A1.Flex
I followed all of the instructions from https://docs.oracle.com/en-us/iaas/Content/Compute/Tasks/enablingserialconsoleaccess.htm in regards to enabling the serial connection but can't get it to work.
Attempting to start it manually with `sudo systemctl stop getty@ttyS0` results in failure:
/dev/ttyS0: not a tty
Thanks for your help in advance!
