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 inter-
       face 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 func-
       tionality 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.
