The correct setting is 38,400 N,8,2. It is set in main.cpp. I will have to update the documentation.
Please check the defines.h file. Is USE_SCREEN_DUMP enabled (not commented out with leading '//')? That changes the baud rate from 38400 to get faster screen dumps. Unless you are generating screen dumps for documentation, USE_SCREEN_DUMP should be commented out.
The blue CAT activity is only visible if the USE_CAT_ACTIVITY line (in defines.h) is enabled.

Here are some other things to try:
Try reloading the firmware.
Cycle the power on the uBitx. With the stock uBitx, that will require unplugging the USB cable as well as turning the radio off with the volume knob as the Arduino gets power from both sources. ?
On the FLRig Xcvr configuration screen, verify the settings and click the INIT button.
