Super simple.
sudo pico /etc/ppp/pap-secrets
With the keyboard arrows browse down until you see this:
# UserIDs that cannot use PPP at all. Check your /etc/passwd and add any
# other accounts that should not be able to use pppd!
guest hostname "*" -
master hostname "*" -
root hostname "*" -
support hostname "*" -
stats hostname "*" -
Type a # at the beginning of the line for guest.
Type Control X ( shown as ^X on the pico menu) , which will ask for Save
(you reply Yes) and exit.
The job is done.

PS: Since you are a beginner: some critical security files are protected
and reserved for the superuser ("roo"). When accessing any such file the
line command needs to be prefixed with sudo
This is why the file manager does not give access.
There are workaround's but using pico is a far simpler solution for a
beginner.

Jacques,
Thank you _very_ much for your extensive investigation and solution!
I haven't figured out how to edit the /etc/ppp/pap-secrets file. When I access it through the file manager, Ubuntu tells me I don't have the permissions necessary to open the file. Is this something I need to do via the terminal? If so, what are the commands I need to use?
I'm new to Linux, so please forgive my ignorance about this.

Devon and list:
this thread was long and I believe that I solved it -
sufficiently general saga worth being in archive.
Devon has an HSF modem in his Ubuntu 8.04 box.
He correctly installed the driver but could not achieve a
connection.
I have the same modem on my RedHat modified (aka Scientific
Linux) in my box.
I met no problem getting connected first to my University
then to Devon's ISP http://www.nocharge.com/ with S.L.
I then loaded my old Ubuntu 7.10 Live CD, installed the
driver (from the generic file, not the precompiled), from
Linuxant.
Either with wvdial or with the Ubuntu
System->Administration->Network tool, I immediately
got connected to my University but experienced the same
rejection as observed by Devon with his ISP.
I have no scruple disclosing the username, password and
phone number of his ISP because they are publicly displayed
on the Web page quoted above. The username was aptly chosen
as "guest" by the ISP.
The debugging option of pppd (syslog) made me find out that
the cause was a PAP rejection.
Lo and behold, the file /etc/ppp/pap-secrets on the Ubuntu
7.04 Live CD, and probably every Ubuntu distro, contains a
block of restricted user id's to which dialling is
denied. Of course my RedHat based system does not have that
block.
Sure enough, "guest" is in the blacklist !!!
Devon: locate that line in /etc/ppp/pap-secrets , insert a
# at the beginning to make it ignored by pppd, and let me
know if you get connected, as I did. I am really eager to
know that you too can now connect.
I tried with the Ubuntu network manager above, not with
wvdial, because Ubuntu sufficiently mocks Windows in hiding
things and decides for the user what he wants to do without
letting him ask, user assumed to be readily dumbed to the
200 % level by Microsoft. Simply, I never could find how to
disable the Ethernet and Wifi interfaces under Ubuntu: you
disable them, within up to 30 seconds they are back, forcing
routes and DNS's which you do not want for the analog
modem connection.
