Subject: A Packet Driver to go on air with a KISS TNC
To: [e-mail]

For Ham-radio community there is NOS which permits to make experience of tcpip
through amateur radio channals with a TNC.
The second step: We have a tcp-appl. of our interest, for example a Gopher
Client , a Telbin or something else ... and we would like to use it with a
KISSmode TNC to log to our area-router on air.
The problem: Our appl. doesn't threat beyond IP level: We need something
to encapsulate the datagrams in an AX25 point to point UI link. We need
a KISS-TNC packet driver.
If we look at the SLIP8250 Packet Driver we see it to be a serial
link point to point driver not very far from what we need. Thus by adding
a simple AX25 header to every outgoing frame and the minimum overhead to pass
through a kiss-tnc we can easily operate an application like PCG3 (which is a
gopher client) on air.
This is what I did. I have changed little in slip8250 (naming it kiss8250!)
and corrently using it as an interface between any tcpip appl passing
through the air.
If any Ham is interested in developing a 'real' packet driver starting
from this simple experience feel free to call.    73 TNX DE IK5HGN

   If we look at the SLIP8250 Packet Driver we see it to be a serial
   link point to point driver not very far from what we need.

And surely you noticed that I had intended that from the start!  The
code decides at runtime whether it self-identifies as SLIP, KISS, or
AX25.  No one every wrote the code for KISS or AX25, but the potential
is there...

Never used DJGCC, but if it really has a high learning curve, check out
EMX/GCC.  It's a darn fine port of GCC which does support DOS, though you
may have only heard of it associated with OS/2.  It can be run under DOS,
and I think the process is even easier if you get RSX (from CICA/mirrors
programmr/dpmigcc4.zip) and put rsx.exe in the bin directory with gcc.exe
et al.  Then just run gcc/make/whatever.  Plug in RCS and you're set.

Others will have to comment on the code & library differences between
DJGCC & EMX/GCC.

To: [e-mail]

Hey, digi's are Ok, as along as they work at 19.2Kbps or better and
are 1200 ft AGL.  But data repeaters (that will handle 19.2Kbps or
better and are 1200 ft AGL) are better as you just play with the RX/TX
frequencies and not the software.           -- K5YFW

I fully agree with Brian's suggestions. They're mostly consistent with
the way NOS already does it. I used to do it differently, but changed
to the present scheme because it was so much cleaner. You really don't
want variable length ARP packets and monster sockaddr structures.

I've never built NOS with gcc, but I'm *this close* to abandoning
Borland C altogether and going to DJGCC.

The only thing holding me back is the learning curve for
DJGCC. Anybody out there with experience, or who can point me to a FAQ
so I can come up to speed?

Subject: wampes and net takes all cpu
To: Olaf Erb dc1ik <[e-mail]>,

Ok fixed.. during the reinstall on linux, i over looked the fact
that wampes was still expecting a local route via slip and a ttyp0
and on the linux side i forgot to setup the slattach for the ptyp0
and ifconfig sl0 it...
think that this is a known bug in wampes if a route/iface via pty's
is left hanging high and dry.
all functioning correctly now..
Thanks. Barry..

Ok due to many wnos users complaining to me via email and S.F about
my policy of source code only distribution, as of 12:15Z I uploaded
to ftp.ucsd.edu:hamradio/packet/tcpip/incoming/wnos-940815.exe
this is built with:
scc asy netrom all cli/srv nntp pop etc. packet drv etc.
Its without any warrenty, use at your risk.
its complied in 286 mode, i have had this same version running as
a cut down router between ethernet and 4 ax25 ccts running now 36 days
and its lost 15kb memory. from startup.
i have on avg 12-15 ac25 connects via it or useing it. It for MY config
is very stable,

Enjoy..  Barry gm8sau/dc0hk
