Cannot get Serial port to work on P2 B

Hi, looking for bit of help with the serial port on a Pi 2B, I had program that worked fine until I updated to the latest Rasbian today. I was expecting to have to change the references to the serial port to 'serial0', but this did not work ?

Taking a step back I installed minicom and connected pins 8 and 10 together and tried minicom -b 9600 -o -D /dev/serial0 . This works fine on a Pi 3 echoing any key I hit but with the Pi 2 nothing ?

Any suggestions, there is a lot on getting the serial ports on a Pi3 to work but nothing recent I can see for a Pi2

Thanks
