15 Note that the answer to this question won't directly affect the
16 kernel: saying N will just cause the configurator to skip all
17 the questions about amateur radio.

23 tristate "Amateur Radio AX.25 Level 2 protocol"
26 This is the protocol used for computer communication over amateur
27 radio. It is either used by itself for point-to-point links, or to
28 carry other protocols such as tcp/ip. To use it, you need a device
29 that connects your Linux box to your amateur radio. You can either
30 use a low speed TNC (a Terminal Node Controller acts as a kind of
31 modem connecting your computer's serial port to your radio's
32 microphone input and speaker output) supporting the KISS protocol or
33 one of the various SCC cards that are supported by the generic Z8530
34 or the DMA SCC driver. Another option are the Baycom modem serial
35 and parallel port hacks or the sound card modem (supported by their
36 own drivers). If you say Y here, you also have to say Y to one of

40 radio as well as information about how to configure an AX.25 port is
41 contained in the AX25-HOWTO, available from
42 <https://www.tldp.org/docs.html#howto>. You might also want to
43 check out the file <file:Documentation/networking/ax25.rst> in the
44 kernel source. More information about digital amateur radio in
45 general is on the WWW at

51 config AX25_DAMA_SLAVE
52 bool "AX.25 DAMA Slave support"
56 DAMA is a mechanism to prevent collisions when doing AX.25
57 networking. A DAMA server (called "master") accepts incoming traffic
58 from clients (called "slaves") and redistributes it to other slaves.
59 If you say Y here, your Linux box will act as a DAMA slave; this is
60 transparent in that you don't have to do any special DAMA
61 configuration. Linux cannot yet act as a DAMA server. This option
62 only compiles DAMA slave support into the kernel. It still needs to
63 be enabled at runtime. For more about DAMA see
64 <http://www.linux-ax25.org>. If unsure, say Y.

102 The Packet Layer Protocol (PLP) is a way to route packets over X.25
103 connections in general and amateur radio AX.25 connections in
