How to do a basic configuration of AX25 on your raspberry pi
 
First prepare to configure the Pi to use its header serial port to comm with TNCPi


from user login:
$ sudo vi /boot/cmdline.txt (or use  your favorite editor)

Edit this file to remove the lines that read
console=ttyAMA0, 115200
and
kgdboc=ttyAMA0, 115200


and then

$ sudo vi /etc/inittab (again, or use your favorite editor)

at the bottom of the file, remove or comment out the line that reads:
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100



This tells the Pi not to use this port for console and stdio.

Next, install AX25

$ sudo apt-get install ax25-tools
$ sudo apt-get install ax25-apps

Then configure it for your own call sign

$ sudo vi /etc/ax25/axports

and edit the default contents to read (use your own callsign please!)

1	AG6QO-10	19200	236	2	TNC1
2	AG6QO-11	19200	236	2	TNC2

Now attach the serial port to AX25

$sudo kissattach /dev/ttyAMA0 1 10.1.1.1

Now you can listen to the port in KISS mode:

$ sudo axlisten -a

You can open a QSO by:
$ axcall 1 W6THEIRCALL
