■Any of the following baud rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200. (Note that the COM port must be set to 19200 baud to view all the system initialization messages.)

■8 data bits

■no parity

■1 stop bit

■no hardware flow control

Refer to the documentation that accompanies the terminal emulation software for more information.
