title: Save serialport list with meteor
body: <p>I use the serialport package in my app (<a href="https://github.com/voodootikigod/node-serialport" rel="nofollow">https://github.com/voodootikigod/node-serialport</a>).
  This code is just working fine on the server :</p>
  
  <pre><code>Meteor.startup(function () {
    SerialPort = Meteor.npmRequire('serialport');
  });
  
  
  Meteor.methods({
    serialPortsRefresh: function () {
  
      SerialPort.list(function (err, ports) {
  
  
        ports.forEach(function(port) {
          console.log(port.comName);
        }); 
  // Config.insert(ports);
        return ports;
      });  
  
    }
  });
  </code></pre>
  
  <p>Now i want to save this list in a collection to expose it to the client.
  What is the best solution ?</p>
  
  <p>When i uncomment Config.insert(ports); i've the error :</p>
  
  <pre><code>throw new Error("Meteor code must always run within a Fiber. " +  
  </code></pre>
  
  <p>Thanks in advance !</p>
