Interesting discussion about multiple serial on Arduino zero.

you can follow this tutorial to make multiple serial ports (without having to modify the board package) its pretty easy!

I'm closing this for now, multiple serial ports are interesting, however there are no plans to support this feature in this core for now.

The Adafruit tutorial @ladyada linked to is a great resource for those wanting to modify the core to create more Sercom based port instances.
