Networking Max messages via UDP
The simplest way to communicate over the internet in Max is by sending Max messages as UDP packets. The udpsend and udpreceive objects make that very easy. Tell the udpsend object what IP address to send to and what virtual port number to use, and tell the udpreceive object on the other computer the same port number. (Needless to say, for two-way communication, you just create objects to send and receive in the other direction.) In this example we use the IP address 127.0.0.1 which is a synonym for 'localhost', the same computer, so that you can see the messages being passed from one object to the other.
