|
KISS is a protocol used for the exchange of data between a computer
|
and a Terminal Node Controller (a small embedded system commonly
|
used for networking over AX.25 amateur radio connections; it
|
connects the computer's serial port with the radio's microphone
|
input and speaker output).
|
|
Although KISS is less advanced than the 6pack protocol, it has
|
the advantage that it is already supported by most modern TNCs
|
without the need for a firmware upgrade.
|
|
To compile this driver as a module, choose M here: the module
|
will be called mkiss.

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

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

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

This is one of two drivers for Baycom style simple amateur radio
|
modems that connect to a serial interface. The driver supports the
|
ser12 design in full-duplex mode. In addition, it allows the
|
baudrate to be set between 300 and 4800 baud (however not all modems
|
support all baudrates). This is the preferred driver. The next
|
driver, "BAYCOM ser12 half-duplex driver for AX.25" is the old

driver and still provided in case this driver does not work with

your serial interface chip. To configure the driver, use the sethdlc
