Feedback from experienced MMBasic users is always welcome. Hello Manfred! I am currently working with the serial interface that I connect to the VGA-Pico. When I looked at your program for it, I noticed that the RX/TX pin assignments are not specified in the source code—for example: `SETPIN GP5, GP4, COM2`. A beginner might get stuck on this. Hello v.lenzer, Thank you for pointing that out. You're absolutely right. A beginner should not have to guess which pins are assigned to COM2. I will update the example and explicitly include the required SETPIN statement so that the program is completely self-contained and can be copied and run without referring back to the surrounding text. Thanks again for the helpful suggestion!
