menuconfig HAMRADIO
depends on NET && !S390
bool "Amateur Radio support"
help
If you want to connect your Linux box to an amateur radio, answer Y
here. You want to read <https://www.tapr.org/>
and more specifically about AX.25 on Linux
<http://www.linux-ax25.org/>.
Note that the answer to this question won't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about amateur radio.

config AX25
tristate "Amateur Radio AX.25 Level 2 protocol"
depends on HAMRADIO
help
This is the protocol used for computer communication over amateur
radio. It is either used by itself for point-to-point links, or to
carry other protocols such as tcp/ip. To use it, you need a device
that connects your Linux box to your amateur radio. You can either
use a low speed TNC (a Terminal Node Controller acts as a kind of
modem connecting your computer's serial port to your radio's
microphone input and speaker output) supporting the KISS protocol or
one of the various SCC cards that are supported by the generic Z8530
or the DMA SCC driver. Another option are the Baycom modem serial
and parallel port hacks or the sound card modem (supported by their
own drivers). If you say Y here, you also have to say Y to one of
those drivers.
Information about where to get supporting software for Linux amateur
radio as well as information about how to configure an AX.25 port is
contained in the AX25-HOWTO, available from
<https://www.tldp.org/docs.html#howto>. You might also want to
check out the file <file:Documentation/networking/ax25.rst> in the
kernel source. More information about digital amateur radio in
general is on the WWW at
<https://www.tapr.org/>.
To compile this driver as a module, choose M here: the
module will be called ax25.
config AX25_DAMA_SLAVE
bool "AX.25 DAMA Slave support"
default y
depends on AX25
help
DAMA is a mechanism to prevent collisions when doing AX.25
networking. A DAMA server (called "master") accepts incoming traffic
from clients (called "slaves") and redistributes it to other slaves.
If you say Y here, your Linux box will act as a DAMA slave; this is
transparent in that you don't have to do any special DAMA
configuration. Linux cannot yet act as a DAMA server. This option
only compiles DAMA slave support into the kernel. It still needs to
be enabled at runtime. For more about DAMA see
<http://www.linux-ax25.org>. If unsure, say Y.

config NETROM

NET/ROM is a network layer protocol on top of AX.25 useful for
routing.
A comprehensive listing of all the software for Linux amateur radio
users as well as information about how to configure an AX.25 port is
contained in the Linux Ham Wiki, available from

help
The Packet Layer Protocol (PLP) is a way to route packets over X.25
connections in general and amateur radio AX.25 connections in
particular, essentially an alternative to NET/ROM.
