Serial.read() help

Hi,

I am also trying to connect two pc Arduino because I do not have outputs for connecting to the GLCD.

I need to send value from my nunchuck and temp sensor to another Arduino.
I've used the code here on the forum but what I can not handle is negative numbers.

I have negative numbers that I have to use in my other Arduino.
What I need is something like:
x = 50 or x = -50 can be positive or negative numbers
y = 50 or y = -50 can be positive or negative numbers and
temp = 25 or temp = -2

Desire is to send all this in a string such as for example
*- 50 79 25, all numbers can be a digit or more and could be negative.
or maybe something like this
*x=value y=value temp=value

Best regards (sorry my english)
