/*
|
|
|
|
* This dissector handles the "KISS" protocol as implemented by the
|
|
|
|
* Linux kernel.
|
|
|
|
*
|
|
|
|
* The original definition of the KISS protocol can be found here:
|
|
|
|
* http://www.ka9q.net/papers/kiss.html
|
|
|
|
* and here:
|
|
|
|
* http://www.ax25.net/kiss.aspx
|
|
|
|
*
|
2012-10-22 20:46:47 +00:00
|
|
|
* The Linux implementation does not appear to attempt to implement that
|
|
|
|
* protocol in full. It does provide the ability to send a KISS command via
|
2012-08-02 06:45:51 +00:00
|
|
|
* ax25_kiss_cmd() and internally will send FULLDUPLEX KISS commands if
|
|
|
|
* DAMA is enabled/disabled.
|
|
|
|
* i.e.:
|
|
|
|
* ax25_dev_dama_on sends FullDuplex ON
|
|
|
|
* ax25_dev_dama_off sends FullDuplex OFF
|
|
|
|
*
|
|
|
|
* Data frames are prefixed with a "Data Frame" command but the port appears to
|
|
|
|
* be always 0.
|
|
|
|
*
|
|
|
|
* Abstract from http://www.ka9q.net/papers/kiss.html
|
|
|
|
* --------------------------------------------------
|
|
|
|
* For reference the first byte of a KISS frame is the frame type and the TNC
|
|
|
|
* port number,
|
|
|
|
* LSB 4 bits = frame type,
|
|
|
|
* MSB 4 bits = port number.
|
|
|
|
*
|
|
|
|
* The frame types are:
|
|
|
|
* Command Function Comments
|
|
|
|
* 0 Data frame The rest of the frame is data to
|
|
|
|
* be sent on the HDLC channel.
|
|
|
|
*
|
|
|
|
* 1 TXDELAY The next byte is the transmitter
|
|
|
|
* keyup delay in 10 ms units.
|
|
|
|
* The default start-up value is 50
|
|
|
|
* (i.e., 500 ms).
|
|
|
|
*
|
|
|
|
* 2 P The next byte is the persistence
|
|
|
|
* parameter, p, scaled to the range
|
|
|
|
* 0 - 255 with the following
|
|
|
|
* formula:
|
|
|
|
*
|
|
|
|
* P = p * 256 - 1
|
|
|
|
*
|
|
|
|
* The default value is P = 63
|
|
|
|
* (i.e., p = 0.25).
|
|
|
|
*
|
|
|
|
* 3 SlotTime The next byte is the slot interval
|
|
|
|
* in 10 ms units.
|
|
|
|
* The default is 10 (i.e., 100ms).
|
|
|
|
*
|
|
|
|
* 4 TXtail The next byte is the time to hold
|
|
|
|
* up the TX after the FCS has been
|
|
|
|
* sent, in 10 ms units. This command
|
|
|
|
* is obsolete, and is included here
|
|
|
|
* only for compatibility with some
|
|
|
|
* existing implementations.
|
|
|
|
*
|
|
|
|
* 5 FullDuplex The next byte is 0 for half duplex,
|
|
|
|
* nonzero for full duplex.
|
|
|
|
* The default is 0
|
|
|
|
* (i.e., half duplex).
|
|
|
|
*
|
|
|
|
* 6 SetHardware Specific for each TNC. In the
|
|
|
|
* TNC-1, this command sets the
|
|
|
|
* modem speed. Other implementations
|
|
|
|
* may use this function for other
|
|
|
|
* hardware-specific functions.
|
|
|
|
*
|
|
|
|
* FF Return Exit KISS and return control to a
|
|
|
|
* higher-level program. This is useful
|
|
|
|
* only when KISS is incorporated
|
2015-04-27 15:08:09 +00:00
|
|
|
* into the TNC along with other
|
2012-08-02 06:45:51 +00:00
|
|
|
* applications.
