Now start minicom this way to edit the configuration :
$ minicom -s
In the menu, select Serial Port Configuration and :
press A and update the serial port path with the one you found in dmesg
press E and then C to change the speed to 9600
press F to switch off the hardware flow control
select Save the configuration as… and name it as, let’s say, “cisco”
You should be able to connect right now. Next time, just start Minicom like this :
