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 ------------------------------ Date: Thu, 15 Sep 94 22:50 EDT From: nelson@crynwr.com (Russell Nelson) Subject: A Packet Driver to go on air with a KISS TNC To: TCP-Group@UCSD.EDU Date: Thu, 15 Sep 94 21:48:01 +02 From: "Alessandro Agostini" 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... -russ http://www.crynwr.com/crynwr/nelson.html Crynwr Software | Crynwr Software sells packet driver support | ask4 PGP key 11 Grant St. | +1 315 268 1925 (9201 FAX) | What is thee doing about it?

Anybody out there with experience, or who can point me to a FAQ > so I can come up to speed? 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. --Don Loflin ------------------------------ Date: Thu, 15 Sep 94 10:18:00 edt From: Adminstrator Subject: Mail failure To: dayhub!3445a!ucsd.edu!TCP-Group@prowler.daytonoh.NCR.COM User mail received addressed to the following unknown addresses: GPPGDAYTON/GPPGPOST/lshannon ------------------------------------------------------------------------------ Return-Path: Received: from prowler.daytonoh.ncr.com by gppgpost.daytonoh.ncr.com id <2E7857C7@gppgpost.daytonoh.ncr.com>; Thu, 15 Sep 94 10:18:47 edt Received: by prowler.daytonoh.ncr.com; 14 Sep 94 15:24:57 EDT Received: by dayhub.DaytonOH.NCR.COM; 14 Sep 94 15:24:51 EDT Received: by 3445a.DaytonOH.NCR.COM; 14 Sep 94 15:24:53 EDT id AA779571782 Wed, 14 Sep 94 15:43:02 EST Date: Wed, 14 Sep 94 15:43:02 EST From: TCP-Group@ucsd.edu Message-Id: <9408147795.AA779571782@WPDSMTP.DaytonOH.NCR.COM> To: tcp-group-digest@ucsd.edu Subject: TCP-Group Digest V94 #202 Large message has been converted into an attachment. ------------------------------ Date: Thu, 15 Sep 94 12:38:00 edt From: Adminstrator Subject: Mail failure To: dayhub!3445a!ucsd.edu!TCP-Group@prowler.daytonoh.NCR.COM User mail received addressed to the following unknown addresses: GPPGDAYTON/GPPGPOST/lshannon ------------------------------------------------------------------------------ Return-Path: Received: from prowler.daytonoh.ncr.com by gppgpost.daytonoh.ncr.com id <2E78789C@gppgpost.daytonoh.ncr.com>; Thu, 15 Sep 94 12:38:52 edt Received: by prowler.daytonoh.ncr.com; 15 Sep 94 12:34:58 EDT Received: by dayhub.DaytonOH.NCR.COM; 15 Sep 94 12:34:50 EDT Received: by 3445a.DaytonOH.NCR.COM; 15 Sep 94 12:35:03 EDT id AA779647902 Thu, 15 Sep 94 12:51:42 EST Date: Thu, 15 Sep 94 12:51:42 EST From: TCP-Group@ucsd.edu Message-Id: <9408157796.AA779647902@WPDSMTP.DaytonOH.NCR.COM> To: tcp-group-digest@ucsd.edu Subject: TCP-Group Digest V94 #203 Received: by ccmail from 3445a.DaytonOH.NCR.COM >From ncrhub1!ucsd.edu!owner-tcp-digest@dayhub.DaytonOH.NCR.COM X-Envelope-From: ncrhub1!ucsd.edu!owner-tcp-digest@dayhub.DaytonOH.NCR.COM Received: by 3445a.DaytonOH.NCR.COM; 15 Sep 94 12:30:04 EDT Received: by dayhub.DaytonOH.NCR.COM; 15 Sep 94 12:29:32 EDT Received: from ncrgw1 by ncrhub1.NCR.COM id bm10928; 15 Sep 94 12:08 EDT Received: by ncrgw1.NCR.COM; 15 Sep 94 12:03:07 EDT sendmail 8.6.9/UCSD-2.2-sun Thu, 15 Sep 1994 04:30:08 -0700 for tcp-digest-list Received: by ucsd.edu; id EAA15098 sendmail 8.6.9/UCSD-2.2-sun Thu, 15 Sep 1994 04:30:06 -0700 for tcp-group-ddist Message-Id: <199409151130.EAA15098@ucsd.edu> Date: Thu, 15 Sep 94 04:30:02 PDT From: Advanced Amateur Radio Networking Group Errors-To: TCP-Group-Errors@UCSD.EDU Reply-To: TCP-Group@ucsd.edu Precedence: Bulk Subject: TCP-Group Digest V94 #203 To: tcp-group-digest@ucsd.edu TCP-Group Digest Thu, 15 Sep 94 Volume 94 : Issue 203 Today's Topics: ax25 linux implementation?

To: tcp-group@ucsd.edu 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 In Gerry's message of 14 Sep 1994 at 0536 CDT, he writes: > Rob sez: > > > > *** In reply to mail from Brian Kantor, ....: > > > The way you handle direct vs digi paths to stations is > > > > > > 1) get rid of the digi.

To: brian@nothing.ucsd.edu 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.
