FRDM-KL26Z & Segger UART problem

I have a FRDM-KL26Z board, flashed with the latest Segger JLink software, and I can't get the UART0 receive to work. Measuring with a DVM, I see that the designated RX pin (PTA1) is floating, meaning that the debugger chip is not driving the pin. The transmit direction, on the other hand, is working fine.

I can pull up the pin in the KL26, however it is still not being driven by the debugger. What am I doing wrong?

 

Thanks,
