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

```auto
OPTION SERIAL CONSOLE COM1: GP0,GP1,Both

```

Is there something I’m missing?

I think it’s the : after com1. I got mine working with

```auto
OPTION SERIAL CONSOLE COM1,GP0,GP1,BOTH

```
