0010 If you want to connect your Linux box to an amateur radio, answer Y
0011 here. You want to read <https://www.tapr.org/>
0012 and more specifically about AX.25 on Linux
0013 <http://www.linux-ax25.org/>.
0014
0015 Note that the answer to this question won't directly affect the
0016 kernel: saying N will just cause the configurator to skip all
0017 the questions about amateur radio.

0026 This is the protocol used for computer communication over amateur
0027 radio. It is either used by itself for point-to-point links, or to
0028 carry other protocols such as tcp/ip. To use it, you need a device
0029 that connects your Linux box to your amateur radio. You can either
0030 use a low speed TNC (a Terminal Node Controller acts as a kind of
0031 modem connecting your computer's serial port to your radio's
0032 microphone input and speaker output) supporting the KISS protocol or
0033 one of the various SCC cards that are supported by the generic Z8530
0034 or the DMA SCC driver. Another option are the Baycom modem serial
0035 and parallel port hacks or the sound card modem (supported by their
0036 own drivers). If you say Y here, you also have to say Y to one of
0037 those drivers.

0039 Information about where to get supporting software for Linux amateur
0040 radio as well as information about how to configure an AX.25 port is
0041 contained in the AX25-HOWTO, available from
0042 <https://www.tldp.org/docs.html#howto>. You might also want to
0043 check out the file <file:Documentation/networking/ax25.rst> in the
0044 kernel source. More information about digital amateur radio in
0045 general is on the WWW at
0046 <https://www.tapr.org/>.

0056 DAMA is a mechanism to prevent collisions when doing AX.25
0057 networking. A DAMA server (called "master") accepts incoming traffic
0058 from clients (called "slaves") and redistributes it to other slaves.
0059 If you say Y here, your Linux box will act as a DAMA slave; this is
0060 transparent in that you don't have to do any special DAMA
0061 configuration. Linux cannot yet act as a DAMA server. This option
0062 only compiles DAMA slave support into the kernel. It still needs to
0063 be enabled at runtime. For more about DAMA see
0064 <http://www.linux-ax25.org>. If unsure, say Y.
