NAME

6       kissparms - Configure KISS TNCs.

SYNOPSIS

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

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       -p port     Sets the port that is being configured.
32
33       -f y|n      This  sets  the  TNC into either full duplex ``y'', or half
34                   duplex ``n'' mode.
35
36       -h hardware This is used to set hardware specific parameters.
37
38       -e FEC error correction level
39                   Sets the FEC error correction level in  a  DSP  card  based
40                   modem  (KISS  parameter  8).  Larger correction level means
41                   better noise resistance, but slower throughput  on  a  good
42                   connection. This is an experimental feature found in a QPSK
43                   modem for the Motorola DSP56001 based DSP4  and  EVM  cards
44                   only.
45
46       -l txtail   Sets  the  TX Tail time in milliseconds. Note that the com‐
47                   mand to the TNC only operates in steps of ten milliseconds,
48                   so only use values like 10, 20 etc.
49
50       -r persist  Sets  the  persist  value.  This parameter is scaled to the
51                   range 0 to 255.
52
53       -s slottime Sets the slottime in milliseconds. Note that the command to
54                   the TNC only operates in steps of ten milliseconds, so only
55                   use values like 10, 20 etc.
56
57       -t txdelay  Sets the TX Delay in milliseconds. Note that the command to
58                   the TNC only operates in steps of ten milliseconds, so only
59                   use values like 10, 20 etc.
60
61       -v          Display the version.
62
63       -x          Takes the TNC out of KISS mode back into  ``normal''  mode.
64                   This  command  is  manufacturer  specific but works in many
65                   cases. This option overrides all options  except  the  port
66                   number.
