You are not at wrong tree, that program is from era before present
pseudo-tty system, when the stupid way it does things did work.

mkiss users are very rare indeed...


I have rewritten mkiss a bit to use modern pty:s, and it is in this
package:

  http://ham.zmailer.org/oh2mqk/libax25/ax25-tools-0.0.9-3.tar.gz

but to use it, you will need also my  libax25  from same directory.
After you take it into use, the information on HOWTO is plain wrong.
See  "man mkiss".   The mkiss will also need associated kissattach.

I did also rework the  kissattach   so that you do not need to set
IP address on AX.25 interface.

My libax25 changes have made it to  cvs@xxxxxxxxxxxxxxxxxx:/home/ax25-cvs
but tools changes are still in the pipeline..  Apparently I have to push
at them again.
