Problem with emacs and keys

[angelfly]

I'm having trouble trying to get emacs to recognize alt-shift-enter. It work fine with the X version of emacs but I prefer running it with the -nw or from the standard terminal since I don't always need X. I've tried C-h k and in the X version it recognizes it as M-S-RET while in in the console or with -nw it recognizes it as M-RET. The shift key is working since I can use S-DEL and query other shifted keys that aren't defined such as S-F5.
