Lexmark Printer X3480 and WinMe

I have this All in One Printer. It includes a Scanner
and a Fax utility.
The Fax utility very rarely works. Most of the time
its error is "Modem not available"
In XP the fax set-up automatically pick up the Modem's name and port but in
WinMe it only says"Modem found on Port 3" which is correct it cannot pick
the name of the modem in the set-up page. the set-up page entry
in the fax utility cannot be edited manually.

Can any user of this type printer can help?
Thanks.
