As shown: 9600 baud inverted, always enabled
problems using the SEROUT command to send
codes to the PAK. Many Basic Stamp-compatible
compilers have these commands too.
Sample Basic Stamp II Code
With the circuit above, connect the RX pin to pin 0
of a Basic Stamp II and an LED (with a 220 ohm
resistor in series between P3 and ground).
Then you can use the following code to make the
LED grow brighter and brighter:
serout 0,84,[$85]
top:
for B1=0 to 255
serout 0,84,[$27,B1]
