# Berta H10 - Debug port

Berta H10 has a serial debug port used by RIOT to send the debug messages. To read the messages on this port you need and USB to Serial interface like the @article='USB-3V-SER' and a serial terminal emulator configured at 115200,8,N,1.

If you are using a Raspberry Pi, a [FOX Board D27](/foxd27) or a Linux Debian/Ubuntu PC you could install <code>tio</code> by typing:

	sudo apt update
	sudo apt install tio
	
Then insert the USB to serial adapter and type:	

	tio -m INLCRNL /dev/ttyUSB0
	
	[tio 19:17:08] tio v1.32
	[tio 19:17:08] Press ctrl-t q to quit
	[tio 19:17:08] Connected

Turn on the Berta H10 and you will start to receive the debug messages send by the Berta-H10:
