Can you publish what you've got so far?

Add a debug node to the serial Node so you can see what you are sending.

If you have been clever then there is a character between the two values that you know. Splitting on a character in a javascript function is easy and a quick google will lead to lots of tutorials for how to do it.

so your screenshot shows a red triangle 🔺 on the serial node which means it’s not configured correctly.

Add a debug to the serial node so you can see what it is sending when configured.  
Without seeing what the message is, and what your function is it is difficult to suggest anything else

Taking another look, if you mean you don't know how to send some to output1 and something else to output 2 , the docs have an example [https://nodered.org/docs/writing-functions#multiple-outputs](https://nodered.org/docs/writing-functions#multiple-outputs)

Isn’t the “switch” and “change” nodes enough for your application?
