Who or what determines the ownership of those devices?
udev does.
Thanks Marcus - udev is new to me, so these are potentially stupid questions: /etc/udev/rules.d/50-udev.rules: KERNEL=="tty[A-Z]*", NAME="%k", GROUP="uucp" Seems to say that ttyIx will have group=uucp - which I was hoping for. /etc/udev/rules.d/45-isdn.rules doesn't say anything about ttyIx at all. So, although 50-udev.rules seem to indicate that ttyIx will have group=uucp, they still end up with group=root. /dev/ttyIx are also listed in /etc/udev/static_devices.txt, but as far as I can see that is not related to ownership. /Per Jessen, Zürich
