Esplora Serial Port Error on Mac OSX

[davidgrud]

Hi I'm unable to connect to the Esplora Serial Port using Mac OSX.
I've tried a number of the examples from the Esplora examples list
using both '/dev/tty.usbmodemfd14311' and '/dev/cu.usbmodemfd14311'

I even tried the gnereic Serial Event example which uploaded fine.
But here's the error i get using '/dev/tty.usbmodemfd14311'

Binary sketch size: 6,060 bytes (of a 28,672 byte maximum)

processing.app.SerialException: Error touching serial port '/dev/tty.usbmodemfd14311'.

Changing the Serial port to '/dev/cu.usbmodemfd14311' results in no error but I have no idea what it is writing to.
If I change the code from Serial. to Keyboard. I can capture the output.
Can anyone help me sort this out?
Thanks
David
