okay. There's a message on howto set up groups to use the modem, but
as I fiddle around more, the way I get the message
ttyS0: Device or resource busy
is if something else already has the serial port open
try doing a ls -l /var/lock
there should be a file
LCK..ttyS0
do a cat /var/lock/LCK..ttyS0
there should be a number and a name.
The name is a user, and the number is a process ID. do a
ps aux | grep <the number you saw>
if something shows up, that program has the serial port open, and you'll
need to deal with it before you run wvdial. otherwise, it's a stale lock
and you can just
rm -f /var/lock/LCK..ttyS0
give that a whirl, and if you start getting
/dev/ttyS0: Permission Denied
read on.
have fun

This should work, but debian doesn't install wvdial as suid, so
I'm going to assume it doesn't need to. Probably all you should
have to do is let the users you want have access to the serial port.
do a ls -l /dev/ttyS0.
here it reports
crw-rw---- 1 root dialout 4, 64 Dec 26 15:28 /dev/ttyS0
so anyone in the dialout group has rw permissions.
then add the users that you want to be able to dial to the dialout
group.
on my systems, I can do this with
adduser username groupname
now. If the serial port looks like
crw------- 1 root root 4, 64 Dec 26 15:28 /dev/ttyS0
you can add a dialout group yourself.
first, do a
addgroup dialout
then a
adduser username dialout
then
chown root:dialout /dev/ttyS*
chmod 660 /dev/ttyS*
and the user that you added to dialout should be able to use wvdial.
hope this helps
