Thanks, Kbeartx and Rongold!! At least it's possible!
I've got cable and thought, albeit incorrectly, that because DSL used the phone line, it need the phone jack--RJ-11.
Now, if I can get her to switch to either DSL, cable or wireless...? We'll see.
Gregg--I don't think we're there yet. Technology changes but some of us remember what 'used to be'!
