Is this the recommended way to get the right-hand-side Grove UART port to work in GPIO mode? (Is that the correct terminology?) I'm using Robert C Nelson's Ubuntu 16.04 image on a BBG. I've tried various things I found over the web, including commenting out the cape_universal=enable text and reboot, but it doesn't seem to make a difference. Code that I wrote to use the right-hand-side Grove UART port in GPIO mode was working with the older Ubuntu 14.04 image, but I cannot figure out what I need to change to make it work in the newer Ubuntu 16.04 images. Problem is I'm a newbie at BB and Groves, and not even sure what to try and debug.
