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 during 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 controlling 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 parameters.

       -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 resistance, but slower throughput  on  a  good
                   connection. 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.
