NAME

6       kissparms - Configure KISS TNCs.

SYNOPSIS

9       kissparms  [-c  crc-type]  -p  <port>  [-f y|n] [-h hw] [-l txtail] [-r
10       pers] [-s slot] [-t txd] [-e feclevel] [-v] [-x] [-X raw]

DESCRIPTION

13       Kissparms is used to dynamically configure KISS  TNCs  that  have  been
14       setup for AX.25 use by kissattach.  This program uses the packet inter‐
15       face to allow it to communicate with the KISS TNC without  interrupting
16       the  AX.25 data stream. Therefore the KISS parameters may be set at any
17       time during the operation of the AX.25 port.
18
19       A full description of the KISS protocol can be found in  the  ARRL  6th
20       Computer  Networking  Conference  papers  pp 38-43. While use of the Tx
21       Tail value is now deprecated, it  has  been  included  to  satisfy  the
22       requirements of users of old TNC firmware.
23
24       Although this utility was originally designed for controlling KISS TNCs
25       connected to a serial port, it is used  by  a  number  of  other  Linux
26       packet radio devices such as the Z8530 SCC driver for controlling their
27       parameters in exactly the same manner. Therefore kissparms  functional‐
28       ity extends to more than KISS TNCs.

OPTIONS

31       -c crc-type Sets  the crc-type to use. For e.g. kernel mkiss: 0 = auto,
32                   1 = none, 2 = flexnet, 3 = smack
33
34       -p port     Sets the port that is being configured.
35
36       -f y|n      This sets the TNC into either full duplex  ``y'',  or  half
37                   duplex ``n'' mode.
38
39       -h hardware This is used to set hardware specific parameters.
40
41       -e FEC error correction level
42                   Sets  the  FEC  error  correction level in a DSP card based
43                   modem (KISS parameter 8).  Larger  correction  level  means
44                   better  noise  resistance,  but slower throughput on a good
45                   connection. This is an experimental feature found in a QPSK
46                   modem  for  the  Motorola DSP56001 based DSP4 and EVM cards
47                   only.
48
49       -l txtail   Sets the TX Tail time in milliseconds. Note that  the  com‐
50                   mand to the TNC only operates in steps of ten milliseconds,
51                   so only use values like 10, 20 etc.
52
53       -r persist  Sets the persist value. This parameter  is  scaled  to  the
54                   range 0 to 255.
55
56       -s slottime Sets the slottime in milliseconds. Note that the command to
57                   the TNC only operates in steps of ten milliseconds, so only
58                   use values like 10, 20 etc.
59
60       -t txdelay  Sets the TX Delay in milliseconds. Note that the command to
61                   the TNC only operates in steps of ten milliseconds, so only
62                   use values like 10, 20 etc.
63
64       -v          Display the version.
65
66       -x          Takes  the  TNC out of KISS mode back into ``normal'' mode.
67                   This command is manufacturer specific  but  works  in  many
68                   cases.  This  option  overrides all options except the port
69                   number.
70
71       -Xraw       Sends the specified raw value to the kiss driver.
