I flashed my PicoCalc with Pico 2W with the latest version of the official repository for the Pico 2. Everything works fine, but connecting the USB C port to my Raspberry Pi 5 via screen /dev/ttyUSB0 I see only question marks and other gibberish coming from the PicoCalc, sending to the PicoCalc fails completely. I tried several baudrates from 9600 to 38400, no difference. I guess the Linux computer expects ut8, what does PicoMite use? BTW using uLisp on the PicoCalc the serial connection works fine. Connecting to a MacBook does not work too.
Problem solved. On the Raspberry Pi using
screen /dev/ttyUSB0 115200, cs8, -parenb, -cstopb
did the trick, which was proposed by the Claude AI agent.
