The port does not show up in CUPS
after I give permission to the port (chmod 777 /dev/ttyS0)
it shows up but after a reboot not any more.
I tried to make it permanent by adding the user in uucp, with no luck
then added the line
KERNEL=="ttyS[0-9]*", NAME="tts/%n", SYMLINK+="%k", GROUP="uucp", MODE="0777"
in /etc/udev/rules.d/90-local.rules and my system froze up.
I use Lubuntu 12.04
Thanks in advance,
