The OPTAscope will display a new waveform for each value incrementing in the Debug
Terminal. What you are seeing is the binary signal of that digit sent as 8-bit no-parity
inverted data at a baud rate of 9600, as determined by the

Position the OPTAscope side-by-side with the BASIC Stamp’s Debug Terminal
to see the values in binary being sent by the BASIC Stamp at 9600 bps.

the serial data. Baudmode is a code number that corresponds to a specific baud rate, bit
number, parity and invert status. OutputData lists variables, constants, expressions and
formatters that determine the format of the outgoing data.
