The console cable is in good condition and the terminal 

(HyperTerminal for example) parameter settings are 

correct. Refer to section 2.4.1  “Configuring Terminal 

Parameters” for information about terminal parameter 

settings. 

Garbled characters on the terminal 

Make sure you have set on your terminal the following 

parameters correctly (HyperTerminal):  

z

 

Bits per second = 9600 

z

 

Data bits = 8 

z

 

Parity = None 

z

 

Stop bits = 1 

z

 

Flow control = None 

z

 

Terminal emulation = VT100 or Auto detect 

Reconfigure the parameters if their values are different from the 

above.
