Where is serial console going?

When running Ubuntu Linux on the Firefly-rk3399, where is the serial console going?
I see a process running that looks like a serial console:
$ ps ax | grep agetty
/sbin/agetty --keep-baud 115200 38400 9600 ttyFIQ0 vt220

Is that the serial debug port?
When I connect to that, I don't see anything.

Be concern about baud rate.

I was able to see the data when it had the Android image installed.

Even if the baud rate is wrong, I should see garbage; but I get nothing.
