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).

vim /etc/wvdial.conf

It is a configuration file you need to open with an editor. It is
nothing to execute.
