NAME
       kissparms - Configure KISS TNCs.

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

DESCRIPTION
       Kissparms is used to dynamically configure KISS TNCs  that
       have been setup for AX.25 use by kissattach.  This program
       uses the packet interface to allow it to communicate  with
       the  KISS  TNC without interrupting the AX.25 data stream.
       Therefore the KISS parameters may be set at any time  dur-
       ing the operation of the AX.25 port.

       A  full  description  of the KISS protocol can be found in
       the ARRL 6th  Computer  Networking  Conference  papers  pp
       38-43.  While  use of the Tx Tail value is now deprecated,
       it has been included to satisfy the requirements of  users
       of old TNC firmware.

       Although this utility was originally designed for control-
       ling KISS TNCs connected to a serial port, it is used by a
       number  of  other  Linux  packet radio devices such as the
       Z8530 SCC  driver  for  controlling  their  parameters  in
       exactly the same manner. Therefore kissparms functionality
       extends to more than KISS TNCs.

OPTIONS
       -p port     Sets the port that is being configured.

       -f y|n      This sets the  TNC  into  either  full  duplex
                   ``y'', or half duplex ``n'' mode.

       -h hardware This  is used to set hardware specific parame-
                   ters.

       -e FEC error correction level
                   Sets the FEC error correction level in  a  DSP
                   card  based  modem  (KISS parameter 8). Larger
                   correction level  means  better  noise  resis-
                   tance, but slower throughput on a good connec-
                   tion. This is an experimental feature found in
                   a  QPSK  modem for the Motorola DSP56001 based
                   DSP4 and EVM cards only.

       -l txtail   Sets the TX Tail time  in  milliseconds.  Note
                   that  the  command to the TNC only operates in
                   steps of ten milliseconds, so only use  values
                   like 10, 20 etc.

       -r persist  Sets  the  persist  value.  This  parameter is
                   scaled to the range 0 to 255.

       -s slottime Sets the slottime in milliseconds.  Note  that
                   the  command to the TNC only operates in steps
                   of ten milliseconds, so only use  values  like
                   10, 20 etc.

       -t txdelay  Sets  the  TX Delay in milliseconds. Note that
                   the command to the TNC only operates in  steps
                   of  ten  milliseconds, so only use values like
                   10, 20 etc.

       -v          Display the version.

       -x          Takes the TNC  out  of  KISS  mode  back  into
                   ``normal''  mode. This command is manufacturer
                   specific but works in many cases. This  option
                   overrides  all options except the port number.
