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.
