If you have a static IP address, you'll have to login with a script
to activate it.  You can't get a static IP w/o a script.  If you
don't have a static IP, you wont need a script at all!
Here the script that someone sent me to that works with the dialup
scripting tool:

proc main
waitfor "ogin: "
transmit "Pjoe^M"
waitfor "ssword: "
transmit "xxxxxxx^M"
endproc

Replace 'joe' with your login name with a P in front of it to make
zipcon go into PPP and replace 'xxxxxxx' with your password. the ^M is
the command as if you hit the "enter" key, so you need that after your
login and password.
