As root, wvdial works just fine. However, what I am trying to do is set up things so that nonroot users can use wvdial, but I'm running into the following problem. When a user issues: wvdial ispconnection the following error message is returned: Cannot open /dev/ttyS0: Device or Resource Busy In looking at the serial how-to the only possible kludge I found was to change the permissions on /dev/ttyS0. I did this but no joy. Can someone suggest a solution? Currently root has to establish the connection via wvdial and then the users are connected. But I'd like to enable users to establish the ppp without root having to do so). Thanks, Serge
