|  | 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. | 
|  |  |

|  | 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>. |
