config MKISS
tristate "Serial port KISS driver"
depends on AX25 && TTY
select CRC16
help
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.
config 6PACK
tristate "Serial port 6PACK driver"
depends on AX25 && TTY
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>.
To compile this driver as a module, choose M here: the module
will be called 6pack.
config BPQETHER
tristate "BPQ Ethernet driver"
depends on AX25
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 SCC
tristate "Z8530 SCC driver"
depends on ISA && AX25
help
These cards are used to connect your Linux box to an amateur radio
in order to communicate with other computers. If you want to use
this, read
<file:Documentation/networking/device_drivers/hamradio/z8530drv.rst>
and the AX25-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. Also make sure to say Y
to "Amateur Radio AX.25 Level 2" support.
To compile this driver as a module, choose M here: the module
will be called scc.
config SCC_DELAY
bool "additional delay for PA0HZP OptoSCC compatible boards"
depends on SCC
help
Say Y here if you experience problems with the SCC driver not
working properly; please read
<file:Documentation/networking/device_drivers/hamradio/z8530drv.rst>
for details.
If unsure, say N.
config SCC_TRXECHO
bool "support for TRX that feedback the tx signal to rx"
depends on SCC
help
Some transmitters feed the transmitted signal back to the receive
line. Say Y here to foil this by explicitly disabling the receiver
during data transmission.
If in doubt, say Y.
config BAYCOM_SER_FDX
tristate "BAYCOM ser12 fullduplex driver for AX.25"
depends on AX25 && HAS_IOPORT
select CRC_CCITT
help
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
utility available in the standard ax25 utilities package.
For more information on the modems, see
<file:Documentation/networking/device_drivers/hamradio/baycom.rst>.
To compile this driver as a module, choose M here: the module
will be called baycom_ser_fdx. This is recommended.

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 half-duplex mode. This is the old driver. It is
still provided in case your serial interface chip does not work with
the full-duplex driver. This driver is deprecated. To configure
the driver, use the sethdlc utility available in the standard ax25

This is a driver for Baycom style simple amateur radio modems that
connect to a parallel interface. The driver supports the picpar and
par96 designs. To configure the driver, use the sethdlc utility
available in the standard ax25 utilities package.

The YAM is a modem for packet radio which connects to the serial
port and includes some of the functions of a Terminal Node
Controller. If you have one of those, say Y here.
