Scala REPL in Emacs

I like to do my Scala development in Emacs, and from time to time, I use the REPL to test out snippets of code or to load and test some code I've just written. I'm using Scala 2.9.1, and I've noticed that when I open the REPL in a terminal buffer, things are substantially broken. In particular, I am unable to remove any characters from the current line, and cannot move the cursor backward on the current line. This is highly frustrating as any time I mistype something, I have to begin the command anew. I was wondering if anyone else is having this problem using the Scala REPL under Emacs, and if anyone has a potential solution.
