I first used the network configuration application to configure the

I got mesage:Cannot activate network device xxxxxxxx Failed to activate

Logged on yyyyyy@localhost, I opened a terminal and entered the command

Someone suggested that I log on to a terminal as Su_-. I entered Su_- at
the command line and got: bash:Su_- command not found
Did they mean that I reboot, and enter Su_- at user name prompt?
How and where do I invoke Su_-?

It is "su -"! No underscore, "-" is an option and is the short for of
"-l" (-> man su). And on Linux it matters whether you use lower or
capital letters.

You need to create a symlink: ln -s /dev/ttySX /dev/modem (where X is
the number of the serial device).

That did not work, so I logged in as root.
I then entereed wvdial, and got:

How can I execute the command /etc/wvdial.conf with out getting
permission denied? I am assuming that since that I am logged on as
root@localhost that I would have the permission.

vim /etc/wvdial.conf
It is a configuration file you need to open with an editor. It is
nothing to execute.
