    16468 is 8 bit, no parity, inverted, and 84 is 8 bit, no parity, true --
    both are for a BS2 or BS2E.

    True means when the data bits are zero, the Stamp pin is at zero volts, and
    when the data bits are one, the Stamp pin is at 5 volts. Inverted is just
    the opposite -- when the data bits are zero, the Stamp pin is at 5 volts,
    and when the data bits are one, the Stamp pin is at zero volts.

    All true. In addition:

    The 'Inverted' modes are for when you are using
    an RS-232 driver between your Stamp and the other
    device. You would use this on 'pin 16' for
    instance to talk to your PC from the Stamp,
    since the Stamp has a built-in 232 driver on
    that pin.
