Serial communication: 09.15-12.00

1. RS-232
   1. Baud rate : One baud is one electronic state change per second.
   2. Parity : odd, even, or none
   3. Data bits : 5, 6, 7, or 8bits
   4. Stop bits : 1, 1.5, or 2 (often says true = 1 stop bits)
2. Asynchronous Serial IO (SEROUT/SERIN, DEBUG/DEBUGIN)
   1. Debug command uses Asynchronous, 9600 Baud rate, None parity, 8 data bits, 1 Stop bits which is 84 in SEROUT buad mode.
   2. DEBUG variable = SEROUT 16, 84, [variable]
   3. If SEROUT uses Pin 16, the BASIC Stamp uses the dedicated serial output pin
