• COM Port Settings
The Watchdog requires that the COM port on the PC be set to 1200 Baud, 8 Data Bits,
No Parity Bit, and 2 Stop Bits. The requirement for 2 stop bits is important because the
processor uses the idle time between characters to process input data, and take care of
other processing tasks.
