My first guess is this is a permissions problem.
On my systems "ls -l /dev/ttyS0" looks like this:
crw-rw----. 1 root dialout 4, 64 Apr 9 15:54 /dev/ttyS0
And I know that neither Linux user "rd", nor "rivendell" are in the
"dialout" group. Try this:
sudo usermod -a -G dialout rd
Then log out and back in (or reboot). Please report back if this helps.
Best,
