With modems problems often have to do with access permissions on the
device files for the serial port to which the modem is connected. For
example, on a probably not default Redhat 9 installation of mine (it has
got there by being upgraded and upgraded since RH5.2) if, at a terminal
window, I type:
ls -l /dev/ttyS[0123]
I get the following output:
crw-rw---- 1 root uucp 4, 64 Jan 30 2003 /dev/ttyS0
crw-rw-rw- 1 root uucp 4, 65 Dec 17 22:43 /dev/ttyS1
crw-rw---- 1 root uucp 4, 66 Jan 30 2003 /dev/ttyS2
crw-rw---- 1 root uucp 4, 67 Jan 30 2003 /dev/ttyS3
Meaning that access to these character devices is given only to root and
to members of the group uucp, with the exception of /dev/ttyS1, which I
have altered myself, adding read write access for all users, for reasons
that I won't bother to go into.
In the "crw-rw----" above, c means character device (you pass data to it
or receive data from it byte by byte), the first rw- means the owner
user (in this case root) has read and write by not eXecutable permission
over the device the second rw- means that the group (uucp) has read and
write permission but not exectuable permission (it would be rwx if
executable permission was also given) and the last --- means that all
other users have no access permissions over the file.
If your ttyS[0123] files look similar, then you need to make sure your
user is a member of the uucp group. You can do this in the Users and
Groups menu entry of the System Settings menu entry in the redhat menu.
You will need to log your user back in after you made the change.
That might well be the problem and would explain why the wizard said
"modem not found".

Nautilus is the program that draws those desktop icons. Open Nautilus -
double click on one of the desktop icons. Bring down Edit:Preferences
menu and then in the "View" tab you'll see that you can change the zoom
of the icons.
Hope that helps,
