uart_example with PCA10000 not working

[ML]

So this should be a trivially simple demo to run, but I'm obviously doing something wrong. When I build the sample application called "uart_example" in the PCA10000 folder and download it, NRFgo Studio seems to be happy that it downloaded correctly. However, when I open Teraterm and try to connect to the USB dongle with the following settings, I do not see any messages from the device, and it doesn't seem to be sending any.

38.4k, 8-bit, no parity, 1-stop bit, HW flow control.

I believe I have the Jlink CDC driver installed, since my Device Manager shows it as COM3 (JLink CDC UART Port).

I would love any suggestions as to what the issue could be.

Thanks in advance! Micah

More information: If I use the debugger in Keil, I can see it sitting there waiting for an incoming UART packet, so it's clearly never getting data pushed to the application from the terminal. Also, the dongle is listed as V2.2.0, and the code pin definitions for UART match the DK User Guide. Therefore, I think the code configuration of UART is correct.
