NAME

       kissparms - Configure KISS TNCs.

SYNOPSIS

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

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

       -c crc-type Sets  the crc-type to use. For e.g. kernel mkiss: 0 = auto,
                   1 = none, 2 = flexnet, 3 = smack

       -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.

       -Xraw       Sends the specified raw value to the kiss driver.
