Maybe instead of using chown, use chgrp to change the group.

Maybe fix with:

chown root:dialout /dev/ttyS4


Note that even though you have write access to the device (modem), you
still need to have "root" privileges to configure your interface and
routing, etc.

So sudo should be fine for your dialup connection.

In the past, sometimes I ran the GUI as a normal user and then ran the
setup script(s) as root.
