If no problems are found after the above-mentioned items have been checked, the
cause may lie in the Console cable or the settings of the terminal (such as
HyperTerminal) parameters. Please perform the corresponding check.
II. Troubleshooting when the terminal display is illegible
If there is illegible display at the configuration terminal, the cause might lie in the
parameter setting error at the terminal (such as HyperTerminal). Please confirm the
terminal parameter (such as HyperTerminal) settings: baud rate should be set to 9600,
data bit to 8, parity to none, stop bit to 1 and flow control to none, and select VT100 as
terminal emulation.
