You want to read <https://www.tapr.org/> 12 and more specifically about AX.25 on Linux 13 <http://www.linux-ax25.org/>. 14 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. 18 19comment "Packet Radio protocols" 20 depends on HAMRADIO 21 22config AX25 23 tristate "Amateur Radio AX.25 Level 2 protocol" 24 depends on HAMRADIO 25 help 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 37 those drivers. 38 39 Information about where to get supporting software for Linux amateur 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.

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.
