Serial Woes With Pimoroni

I have a Pimoroni Pico2 in my PicoCalc and I can’t use the PicoCalc’s USB to communicate with a PC terminal emulator. If I plug the USB cable into the Pimoroni’s USB, it works fine. Before, I was able to use the PicoCalc’s serial port.
In my options I have

OPTION SERIAL CONSOLE COM1: GP0,GP1,Both

Is there something I’m missing?
