If you are the only user on your system, then you can do that. Otherwise,
you've just allowed everybody to use the modem and dial to those nice
Australian BBS'es :)

The correct thing to do, is to make /dev/ttyS3 owned by root:dialout,
mode 0660 (crw-rw---). Then add any user that must have access to a
dialout device to the group "dialout" (edit /etc/group with "vigr").

If you also happen to run mgetty on the serial port, edit /etc/mgetty.config
and make sure mgetty resets the port modes to root:dialout mode 0660
