axctl man page

axctl — Configure/Kill running AX.25 connections.


axctl [-v] port dest src window|t1|t2|t3|n2|idle|paclen|kill [parm]


The axctl command is designed to be a multi-function command that allows miscellaneous commands to be issued to the Linux AX.25 protocol layer for existing AX.25 connections. The connection is uniquely identified via the combination of port, destination callsign and source callsign, with that information the kernel is able to change the parameters, or abort the connection.

Many of the options are similar to those found in axparms and perform the same function. Only one parameter may be changed on each invokation of axctl.
