nRF51 DK UART to USB not working (Virtual COM port)

Hi all,

I'm having problems into making the virtual COM port of the nRF51 DK work.

The only line in the User guide regarding it's configuration is the following:

"Note: The terminal used must send a DTR signal in order to configure the UART Interface MCU pins."

So what does it mean? Which signals after the DTR signal should I send to configure the baud rate exactly?

And what are the default parameters if I don't send anything and I just want it to work out of the box? I need to know them to configure the nrf UART in code.

I'm using Mac OS X, and when I plug the board the Virtual COM port is detected as /dev/(cu|tty).usbmodem14111. Do I need some driver?

Thanks for your help.
