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.

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.

31	  Note that this driver is still experimental and might cause
32	  problems. For details about the features and the usage of the

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.

89	  This is one of two drivers for Baycom style simple amateur radio
90	  modems that connect to a serial interface. The driver supports the
91	  ser12 design in full-duplex mode. In addition, it allows the
92	  baudrate to be set between 300 and 4800 baud (however not all modems
93	  support all baudrates). This is the preferred driver. The next
94	  driver, "BAYCOM ser12 half-duplex driver for AX.25" is the old
95	  driver and still provided in case this driver does not work with
96	  your serial interface chip. To configure the driver, use the sethdlc
