Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

The Pico's RP2040 that I have been using, I had to solder the headers on myself, maybe I did some damage to them.
This time I just Up loaded the 6.00.02 firmware to another RP2040 that I bought with the headers already soldered on. I'll program the Quadrature Decoder Program in this unit today and I let you know how this works.

Try this from the command line.
> SetPin GP21,GP20,COM2 : Open "com2:115200" As #2
> Print #2, "jumps over the lazy dog" : pause 9 'allow time to transmit
>
Does that also produce an error?

Still trying to do what you asked. It's not working yet and I have to get ready for work now. I'll try it again later.

 I put the PicoMite on my Propeller professional development board and tested GP20 AND GP21 PINS FOR INPUT AND OUTPUT with push button for input and led for output.
I checked GP20 for input and output with the DIN and DOUT COMMANDS. I did the same for GP21 and all works good, so it's not a hardware issue. Comms not working is a software issue. I'll work on it the next time I get a chance using phi199's post above.
