+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
+	  <https://linux-ax25.in-berlin.de>.
+
+	  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
+	  <https://linux-ax25.in-berlin.de>.  If unsure, say Y.
+
+# placeholder until implemented
+config AX25_DAMA_MASTER
+	bool 'AX.25 DAMA Master support'
+	depends on AX25_DAMA_SLAVE && BROKEN
+	help

+	  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 master; 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 explicitly enabled, so if unsure, say Y.
+
+config NETROM
+	tristate "Amateur Radio NET/ROM protocol"
+	depends on AX25
+	help
+	  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
+	  <https://linux-ax25.in-berlin.de>. You also might want to check out

+
+config ROSE
+	tristate "Amateur Radio X.25 PLP (Rose)"
+	depends on AX25
+	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.
