Simple Node script to launch a Telnet connection and control my Pioneer Receiver.

gistfile1.js

var net = require('net');

connection = net.connect(23, '192.168.2.5')
connection.setEncoding('utf8');
connection.on('connect', function(){
    console.log('connected');

    connection.on('data', function(data){
        console.log(data);
    });

    process.stdin.resume();
    process.stdin.setEncoding('utf8');
    process.stdin.on('data', function (chunk) {
        connection.write(chunk + "\r");
    });
});
