6	help
7	  KISS is a protocol used for the exchange of data between a computer
8	  and a Terminal Node Controller (a small embedded system commonly
9	  used for networking over AX.25 amateur radio connections; it
10	  connects the computer's serial port with the radio's microphone
11	  input and speaker output).
12
13	  Although KISS is less advanced than the 6pack protocol, it has
14	  the advantage that it is already supported by most modern TNCs
15	  without the need for a firmware upgrade.

22	depends on AX25 && TTY
23	help
24	  6pack is a transmission protocol for the data exchange between your
25	  PC and your TNC (the Terminal Node Controller acts as a kind of
26	  modem connecting your computer's serial port to your radio's
27	  microphone input and speaker output). This protocol can be used as
28	  an alternative to KISS for networking over AX.25 amateur radio
29	  connections, but it has some extended functionality.
30
31	  Note that this driver is still experimental and might cause
32	  problems. For details about the features and the usage of the
33	  driver, read <file:Documentation/networking/6pack.rst>.

40	depends on AX25
41	help
42	  AX.25 is the protocol used for computer communication over amateur
43	  radio. If you say Y here, you will be able to send and receive AX.25
44	  traffic over Ethernet (also called "BPQ AX.25"), which could be
45	  useful if some other computer on your local network has a direct
46	  amateur radio connection.

51	depends on VIRT_TO_BUS
52	help
53	  This is a driver for high-speed SCC boards, i.e. those supporting
54	  DMA on one port. You usually use those boards to connect your
55	  computer to an amateur radio modem (such as the WA4DSY 56kbps
56	  modem), in order to send and receive AX.25 packet radio network
57	  traffic.
58
59	  Currently, this driver supports Ottawa PI/PI2, Paccomm/Gracilis
60	  PackeTwin, and S5SCC/DMA boards. They are detected automatically.
61	  If you have one of these cards, say Y here and read the AX25-HOWTO,
62	  available from <http://www.tldp.org/docs.html#howto>.
63
64	  This driver can operate multiple boards simultaneously. If you
65	  compile it as a module (by saying M instead of Y), it will be called
66	  dmascc. If you don't pass any parameter to the driver, all
67	  possible I/O addresses are probed. This could irritate other devices
68	  that are currently not in use. You may specify the list of addresses
69	  to be probed by "dmascc.io=addr1,addr2,..." (when compiled into the
70	  kernel image) or "io=addr1,addr2,..." (when loaded as a module). The
71	  network interfaces will be called dmascc0 and dmascc1 for the board
72	  detected first, dmascc2 and dmascc3 for the second one, and so on.
73
74	  Before you configure each interface with ifconfig, you MUST set
75	  certain parameters, such as channel access timing, clock mode, and
76	  DMA channel. This is accomplished with a small utility program,
77	  dmascc_cfg, available at
78	  <http://www.linux-ax25.org/wiki/Ax25-tools>. Please be sure to
79	  get at least version 1.27 of dmascc_cfg, as older versions will not
80	  work with the current driver.
