Quick Example how to read comma separated strings in Unity with SerialCommUnity.

CommaSeparatedMessageListener.cs

// Code example for this Code: 
// https://github.com/DWilches/SerialCommUnity
//
// Below the modified SampleMessageListener to show how to parse comma separated strings

// Start with DemoSceneAutoPoll

 * When creating your message listeners you need to implement these two methods:

		string[] tokens = msg.Split(',');

		// There is also something lik TryParse.

    // will be 'true' upon connection, and 'false' upon disconnection or
    // failure to connect.
