Since you haven't tested your modem yet, the first thing to do would be
running minicom or some other serial terminal on your /dev/ttyS?, issuing
the ATZ command and see if you get OK. There is no point worrying about
anything else as long as you are not sure you have a working modem.

I am giving no guarantees - its been a while...

I suppose you've setup your broadband in either rc.conf or netcfg. If that
is the case, know that these setups are Archlinux specific and there is
basically no software which will touch these. So you always get what you
have specified in rc.conf after a reboot.

And you _can_ have lots of modems and lots of ethernet cables connected to
you computer, and still have your broadband working. With most setups,
data packets to the internet go through the default route (try running
'route'), which is changed after a successful pppd connection and changed
back after it closes (this is not wvdial specific).
