How about some way to make it easy to hook these together.  Something
that doesn't requirea EE degree and many $$$'s worth of equipment.  That
is one thing that makes 1200bps packet attractive.  All you need to buy

There are other versions of NOS that are just as good possibly.  I could
just as easily say that everyone has to use at least a 386 with 4 MB RAM
and run Linux with the AX.25 drivers in the kernel but that wouldn't make
it happen any sooner.  This is a hobby for most of us and we can't
afford to go and buy a special computer for it (even if 286's are dirt cheap).

I'm interested in hearing from anyone running BSD/386 (BSDI); now that I've
got a Unix box at home I'd love to splice it into packet.

And yes; I'm willing to bash out code.

I've been running BSDI at home for many months; before that, the same
machine (a 486 DX2-66) ran an early version of 386BSD. Works great.  I
did have to bring it up to 32 MB of RAM and 1.7GB of disk to do it
justice, especially since I'm a heavy X and GNU Emacs user...

It's on my house Ethernet, which supports two other machines: another
486 running DOS and/or Windows, on which I develop NOS and play Doom,
and a third 486 that runs NOS full time as a router. The NOS router
has a dialup SLIP connection to a Netblazer at work, plus a DRSI
interface to the local packet radio channel.

In that case I suggest you grab two things as well as KA9Q which is the
ultimate AX.25 trace tool 8). Firstly get the Linux AX.25 code from
sunacm.swan.ac.uk:/pub/Linux/Radio. Secondly get the netccitt stuff from
any BSD net-2 archive. The Linux lapb code is derived fromt he netccitt
stuff so it should be easy to retrofit it back into a BSD kernel with the
changes for AX.25 as opposed to LAPB. If you can clone the interface
semantics of bind() etc in the Linux one then you also get to use the
Linux AX.25 user command set with your kernel.

If you can't duplicate the behaviour, or there is a much better way of doing
it let me know. I'd like to be sure the Linux AX.25 system interface is
implementable under BSD, and having the same interface to both would be
good for all concerned.

  Hi folks. I know it is maybe not the place for it, but i showed the Ka9q
  to a local guy and he said that it is impossible to have a finger, ftp
   and a BBS in a PC with MS-DOS, even after i showed a Ka9q to him!! :(.
   Can some kind soul explain to [e-mail] and [e-mail]
    that the Ka9q is a PC router, proxy-arper, and a ftp, smtp and telnet
   (bbs) server?? Please.

  Thank you very much!!

"Can I compile jnos 1.10d for under OS/2 with Borland C for OS/2"

No. JNOS is hardwired into a DOS environment and operates at the hardware
level. PMNOS is a functional equivalent based, in part, on jnos 1.08,
however PMNOS can not be used with ethernet nor with DRSI or PI cards.

Subject: Network Numbers In AppleTalk
To: [e-mail]

I found in NetWize program this comment:

"    One note though, the Network Maps (in PICT format) places alongside of
network number a statement of what protocol type is being used, these notes
were generated as guidlines and are not to be taken literally.  The guidlines
I used was as follows, I shall be providing a method for you to change these
guidlines to suit your network scheme:

Network numbers less than 256 are violations
Network numbers between 257 and 511 are IP Talk
Network numbers between 512 and 767 are EtherTalk Phase 1
Network numbers between 768 and 1023 are EtherTalk Phase 2
Network numbers greater than 1023 are LocalTalk"

Is this an standart in AppleTalk???

Agree.  I've read about the PackeTwin, which (as I recall) can handle an
on-board 9.6 modem (daughterboard?).  It's a little beyond the $125 price
tag mentioned, but not drastically.

Agree on the scope, too.  I do know that I've improved my set-up and
trouble-shooting skills since I walked out of Dayton with one (although
my right arm is now a bit longer after the walk to my vehicle).

The PI2 card is probably closest to what you're talking about.  The
current incarnation handles an on-board 1200 bps modem on it's half-card
PC card, with an interface to an external "high speed" modem (9.6 and
up, 56kpbs proven, and much faster has been demonstrated).

>It might make a good bit wise full duplex regenerator node....

(David steps onto one of his soapboxes...)
I've never liked the idea of bit regenerators.  A decent router/switch
(PC+NOS) that can intelligently decide what to pass and what to not pass
seens to make a lot more sense.  It doesn't transmit data that it doesn't
need to transmit.  Of course, there's a little more latency, but like you
said, we need to get users doing higher speeds.

Well I for one love the card. It does require a quick tune to match the
radio but I did that in 2 minutes and I'm _not_ a hardware person at all.
I guess the PI/3 needs onboard 9600 but other than that its wonderful.

My (percieved) benefit of the central node is to give a real time busy,
thereby (almost) eliminating the very real problem of hidden transmitter
syndrome.  And over any metro area, you are either using extra power
or you will have at least one hidden transmitter (I don't see point
to point to each destination as servicable).

I am for combining the bit regen with the central (cross frequency)
router...
