Does not work on windows

The com ports are simply named "com1", "com2" and so on on windows.
So this will not work.

var eligiblePorts = ports.filter(function(port) {
    return !port.match(/[Bb]luetooth/) && port.match(/\/dev\/tty/);
 });

but this will

var eligiblePorts = ports.filter(function(port) {
    return !port.match(/[Bb]luetooth/);
  });
