Multi-variable serial data

I read the tutorial on multi-variable serial data (RBG serial mixer), but what if I want the receiving end of the serial conection to be another arduino (instead of a computer). This is my first project with ardiuno, and I'm not sure how to make this work without parsing a string for an integer, which I'm not sure how to do with arduino. Could anybody help me? :-?

For converting an integer in string form to a real integer, use the atoi() function. check this thread:

Thanks! That was very helpful.
