HELP NEEDED!!

As most of you know I have  taken  on  the  impossible  task  of  tring  to
maintain  the  World  Wide Packet Radio Digipeater/PBBS Listing and USA-PKT
Listing.  The cost is getting out  of  hand  on  reproduction.  What  I  am
looking  for  (IF POSSIBLE) is the donoation of a Offset Press.  The Offset
Press would be used to reproduce the WWPACKET files on a quarterly or semi-
annual  basis  and  make it available to all at cost of paper, stamps, etc.
If anyone knows of any available Offset Press please let me  know.  I  have
had  a  lot  of  people  ask  for  copies  of these listings.  I will begin
(HOPEFULLY) publishing it on a quarterly basis either on IBM-Formatted disk
or  in  paper-back  form.  It  will be also be available on my landline BBS
(703-680-5970) for anyone who wants it.  Please if you can find  or  see  a
Offset  available  let  me  know.  These  listings  I maintain are the MOST
COMPLETE listing available to any HAM on Packet Radio Bulletin  Boards  and
Digipeaters.  Unlike  one  Company  that  states  that  theres  is the most
complete with 1400 call signs, mine currently has over  2,211  US  and  256
International  call signs and is updated on a daily basis.  And I have just
started on the Internationl files.  There listing only  comes  out  once  a
year  and found to have lots of errors.  The WWPACKET files will be printed
either quarterly or semi-annual or be available on my BBS updated weekly.

Summary: Amateur Packet Radio protocol specs
References: <[e-mail]>

> I am looking for a definition of the protocols used in packet radio.

The AX.25 protocol spec is available in paper form from the ARRL.

NET/ROM's internal protocols are described in the NET/ROM user's manual
>from Software 2000.

The ARPA Internet protocols (TCP/IP, etc) are described in the ARPA RFC
(Request for Comments) series and also in various MIL-STD documents.
RFCs are available over the network to Internet sites. They are also
available from TAPR on floppy disk for the cost of materials and
mailing.  A new book by Douglas Comer on TCP/IP has been published by
Prentice-Hall; it is an excellent introduction to the subject. Several
of us have published several papers in the ARRL Computer Networking
Conference Proceedings regarding the amateur TCP/IP development effort.
These are available from the ARRL.

Formal descriptions of TEXNET's internal protocols haven't been
completely published as far as I know, but pieces of them have appeared
in the ARRL Computer Networking Conference proceedings.

Existing COSI/ROSE code appears to be based on a modified X.25 Packet
layer.  The original X.25 spec is available from several places,
including bound collections of standards (e.g., Data Communications
Standards, edited by Folts, published by McGraw-Hill).  You should be
able to find this or similar references in most technical libraries.
The COSI/ROSE group has also published papers in the ARRL Computer
Networking Conferences, but one must be careful to distinguish between
what has been discussed and promised vs what has actually been done.

Subject:  Looking for Atari ST TCP-IP

I've been waiting for the Atari ST TCP-IP port mentioned last month to
show up somewhere but I haven't been able to find it.  The message said
it was going to louie.ud1.edu but our ftp doesn't know about that
address.
I've checked CANADA01 and RPICICGE on bitnet and SIMTEL20 via ftp but
no luck.  Any chance that the files will make it to one of these places?
(Or better yet, to this address directly.)  Any information would be
appreciated.

Subject: Packet work on commercial radio-modems
Keywords: Commercial radio modems
Reply-To: [e-mail] (Jonathan Sadler)

Has anyone looked at takeing dedicated radio-modems (like the freedom
wireless modem)?  Basically this modem opens a perminant connection to
another station, er. modem, on the same frequency (DIP switch selectable)
The modem then does standard HDLC framing, and watchesfor a special
command sequence to place it in a command mode.  (Gee, doesn't this
sound alot like a standard TNC???)

Differences I have found so far:

    - This uses straight X.25, not AX.25.  Consequently the address field
      is only 8 bits wide, and the modem can only connect to 255 other modems.
    - This modem can do 9600 bps, and claims to do higher (I havn't been
      able to try any other speeds).  Could be interesting for a dedicated
      IP link if we could get KISS up on it....
    - The modem also integrates the tranciever in it.  Different antennas
      are available.  1/4, 3/4, and 1-1/4 wave.  the 1+1/4 wave claims to
      have an 18 mi. range.  All together, the modem and tranciever is
      3"Wx2"Hx4"D.  Kinda small.

Any ideas?  I'm about ready to call the maker of this unit and ask for detailed
info on the internals so that I can get KISS.

Also, does anyone know what kind of commercial stipulations there would be?

Jon

Subject: Re: SLIP Info please?
Summary: SLIP definition
References: <[e-mail]>

I don't think I've seen a formal description of SLIP, but it is very
simple.  It is just a framing technique suitable for carrying IP
datagrams (or whatever you want) on asynchronous links.

Four special characters are defined. They are as follows:

<Frame End>             C0 hex
<Frame Esc>             DB
<Transposed Frame End>  DC
<Transposed Frame Esc>  DD

Transmitter Operation

The transmitter sends the frame a byte at a time, ending it with the
<Frame End> character. If a <Frame End> character occurs in the body of
the frame, it is replaced by the two character sequence <Frame Esc>,
<Transposed Frame End>. Similarly, if a <Frame Esc> character occurs in
the body of the frame, it is replaced by the two byte sequence <Frame
Esc>, <Transposed Frame Esc>.

Receiver Operation

The receiver appends incoming bytes to a reassembly buffer, passing
whatever has been accumulated up to the next layer when it sees a <Frame
End> character. (The <Frame End> itself is not added to the buffer). The
receiver maintains a one-bit "escaped" flag that is set whenever it sees
a <Frame Esc> character.  (The <Frame Esc> character itself is NOT added
to the reassembly buffer). If the receiver then sees either a
<Transposed Frame End> or a <Transposed Frame Esc> while in "escaped"
mode, it is translated to a <Frame End> or a <Frame Esc>, respectively,
and adds it to the reassembly buffer. Regardless of the character
received while in escaped mode, the "escaped" flag is cleared. If the
<Transposed Frame End> or <Transposed Frame Esc> characters are received
while NOT in "escaped" mode, no special action is necessary; they are
added to the reassembly buffer unchanged.

Note that the <Frame End> character is *never* sent over the line except
as an actual end-of-frame indication.

The original SLIP put <Frame End> characters only at the end of each
frame.  I.e., a series of back-to-back frames would be separated by only
a single <Frame End>. I have made a minor, backward compatible change to
the protocol that puts a <Frame End> in front of each frame as well.
This adds a very small bit of overhead (back-to-back frames are now
separated by two <Frame End> characters) but it improves performance
over noisy links by forcing the receiver into a known state at the
beginning of each new frame.

When used to send IP datagrams over phone lines, the datagrams are
encapsulated directly in frames formatted as described here; no
additional header is carried. There has been considerable discussion
about the need for such a header, but nothing has actually come into
use, as far as I know.

I use SLIP in a different way between a system running my TCP/IP
software and a KISS TNC. There I use SLIP style framing to carry AX.25
frames and control messages between the TNC and host, and there is a
one-byte "type" field at the beginning of each frame. For details, see
the paper by K3MC and myself in last year's ARRL Computer Networking
Conference proceedings. (The same article also described SLIP in
detail).

Subject: SLIP Info please?

Can anybody email me more details about SLIP (Serial Link Internet
Protocol)?  I am interested in the possibility of supporting multiple
telnet type login sessions on one physical radio channel, using a
standard, albeit high speed (38.4Kb?) serial line between TNC and
computer.

Does KA9Q do this?  Are other possible sources PD?  I need to have
source code available.  I (read: my employer) would be interested in
discussing commercial licensing at some future point.  For now,
though, folks, I'd just like to know what I'm talking about.

Can you help?

Email ONLY, please.  The .sig path should work just fine.

   Sorry about that.  I've been meaning to get it up on louie.udel.edu
(notice the name), but things have a been a little hectic here.  I'll
take the diskettes to work today and see if I can find a drive to read
them.  At last report, we are having problems with the software that
reads 720K diskettes (3.5 inch).  If this fails, I'll try to get the
format converted some time this weekend, and post early next week.

Subject: IP on a TNC?
Keywords: tcp/ip amprnet


I know that it flies in the face of nature and all that, but has
anybody considered implementing the IP layer of NET.EXE on a TNC?

The idea is that an AMPRNET user can leave the tnc on all the time,
along with the radio, and thus provide IP routing services and keep
the network connected.  A lot of people either do not want to or
cannot leave a PC on 24hrs a day (e.g. because of the noise level :-),
but a TNC is silent.

I am trying to repair a DRAKE TR-4. I was wondering if anyone out there
knows where i may obtain technical/repair manuals for the beast.

                        Thanks in advance,

                           Vaughn  (N2BHA)

Subject: Protocol standards

For a long time I've been irritated by the lack of a standard,
THE standard, for packet-radio file transfer.

There are several protocols in use, like YAPP, KERMIT, XMODEM etc.
YAPP is quite a good one, but the problem is that you need a PC
to use it, and you also "have" to use the YAPP terminalprogram.
Since neither the sourcecode nor some techn. info is available it is
almost impossible to implement it in "homebrew" programs.

KERMIT is perhaps the best protocol to use, because it is already
implemented on the most common computertypes, and complete source is
available.  The disadvantage using KERMIT is that almost all current
mailboxs use YAPP.

Does anybody have any thoughts on this question ????????

deletions occurring within your country for Digipeaters and Packet Bulletin
Boards.  I am maintaining the World Wide Listing of Packet Bulletin  Boards
and  Digipeaters.  Data  can  be  sent  by  mail, packet radio, ARPANET, or
uploaded to my PBBS.  Who ever becomes the Point of Contact will receive  a
disk  from  me  every three months listing all known PBBS's and Digipeaters
World Wide for local distribution.  Here is an easy way to get  a  copy  of
the  list.  It  will  be supplied in 40 track, double sided, double density

addition  It  is  the only accurate (Updated daily) and complete listing of
Digipeaters and PBBS's.  As of 21 June 1988 is has over  2,561  Digipeaters
and  PBBS's  listed.  It  has  Digipeaters  and PBBS's from Canada, France,
Hungary, Italy, Norway, Yugoslavia, Japan, Austrlia,  West  Germany,  Great
Britain,  and the United States.  I would like to see it more complete then
that.  There are a large number of  countries  which  are  not  listed  and
should be.  Here is a chance of producing a COMPLETE listing of Activity in
Packet Radio.

If you want to become the point of contact for your country please  provide
the  following  information  AS  SOON  AS POSSIBLE.  There will only be one

Don,

You may have posted this info before, but are these files available for FTP
access on any machine?

Dan, As of yet I do not have any of the files in any system for FTP.
If anyone out there has an area where I can drop them and make them
available to all I would be glad to upload either the ASCII version
or ARC files.  Any one help out?
