Please select your download baudrate:

2. 19200
3. 38400
4. 57600
5. 115200
0. Return
Enter your choice (0-5):
3 Choose an appropriate download baud rate. For example, if you enter 5, the baud
rate 115200 bps is chosen and the system displays the following information:
Download baudrate is 115200 bps
Please change the terminal's baudrate to 115200 bps and select XMODEM
protocol
Press enter key when ready
Now, press <Enter>.
If you have chosen 9600 bps as the download baud rate, you need not modify the
HyperTerminal's baud rate, and therefore you can skip step 4 and step 5 and proceed
to step 6 directly. In this case, the system will not display the above information.
4 Choose [ File/Properties] in HyperTerminal, click <Configure> in the pop-up dialog
box, and then select the baud rate of 115200 bps in the Console port configuration
dialog box that appears.
