Stamp Editor's Help program has tables that give the
rates and signals. It turns out that 84 is the

designed to receive.

they are sent with formatters, they are sent as the characters that represent the value. If
they are sent without formatters, they will be sent as values, like 22, 12, and 13. We can
send unformatted values like these to the LCD, which will interpret them as control
codes.
Simple Text Messages and Control Codes
Unlike the Debug Terminal, the serial LCD needs to be turned on with a command from
the BASIC Stamp. The LCD has to receive the value 22 from the BASIC Stamp to

If you want to try using the Debug Terminal with
the toolbar via Run → Debug → New. Next, select Run → Identify to see which port your
BASIC Stamp is using. Then, in the Debug Terminal, set the Com Port to match. Note that
you can also change the Debug Terminal’s Baud Rate and other communication parameters.

probably already have the PBASIC Syntax guide. To access it, simply select Index from the
