print objects from both regular Max patches and also M4L will just not print to the Max window. Often they print and then they don't. I'm not sure why. It's definitely a bug as it's very intermittent.

yes, I'm using Max 6.1. I was adding a print message to my serial object. But it's not printing. 

And now I don't know how to find out the name of my serial port.

Any ideas?
