in BASIC Stamp
SEROUT to LCD with P9 or P8 works, but not A2 or A3.
Why?

    A2 and A3 are connected to the Stamp's P11 and P12 pins, respectively. As long as the "A" coprocessor is not programmed to output on A2 and A3, P11 and P12 should be available for use with SEROUT.

    For more details, see page 5 of the MoBoStamp-pe manual and the schematic on page 9.

    I get it.

    A2(P6) on AVR-A is tied to Stamp P11.

    Thanks
