I think the tech. mis-understood you. I never heard of such thing either.
I was just online with a Dell tech asking if a certain Inspiron 15 model had a modem available. (I am shopping for a new laptop). There are some places that I travel where the only way I can get on line is by dial up so I do need that capability.
He told me that you don't need a modem anymore if there is an ethernet card in the computer. I've never heard of this and am skeptical. Can someone set me straight? Thanks!
