</span>The only thing I can offer is that Scratch finds a serial port as /dev/ttyAMA0 as well, implying that on at least one Pi it finds the same port that python does. I don’t think I have any devices that I could even try to connect to. Any suggestions for things that might be around the office?<br>
<br>
I do faintly recall some discussions about Pi serial stuff and having to use the rasp-config utility but that was a long time ago and I don’t seem to have any emails referring to it.<br>
