That's not enough information.  This can depend on how your terminal
interacts with things, or perhaps if you run it in DrScheme or not.
To inspect a difference in behavior just for `read' and `read-line'
you should come up with an expression that shows a difference given
some fixed input (using something like open-input-string).

(I did try several combinations, including yours, and saw no
difference.  If you see a difference in DrScheme then this is
unrelated to what `read'/`read-line' do.)
