 This script tests internal communication between serial ports with the possible lowest (2400) and highest (115200) baudrate.  

 For this example, connect each port's transceiver with the receiver: 

 

 Default settings: 

 

 baud rate: 115200 

 data bits: 8 

 parity bits: 0 

 stop bits: 1 

 receiver timeout: 3s 

 

 

 If the connection is right, you should see the messages shown below for each U(S)ART: 

 

 

 If something goes wrong with the connection, you will see the message for a specific port like below:
