Turns out there is full support for calling real-mode routines; there's even a demonstration program in the package that shows how to call a FTP Software Packet Driver (which was my concern for some time). I'm doing this in stages. Stage 1 is to rename external symbols that conflict with those in the GCC libraries. E.g., psignal() will become ksignal(), alarm() will become kalarm(), etc. At the same time I will attempt to clean up the code to make it compile more cleanly. During this phase I will try to retain backward compatibility with Borland C++ 3.1. When I'm done I'll package everything up and release it as my last Borland-based version. Then I'll start stage 2: translating assembler code and writing any new C code specifically required to run under DJGPP. There are several good reasons for this effort. One is the vastly increased memory space available in protected mode; you'll actually be able to use all that RAM for something useful. I may add some memory-intensive facilities that haven't been practical under DOS, e.g., extended debugging for mbufs and memory blocks. (One drawback to running in protected mode -- the incentive to find and fix minor memory leaks is considerably reduced!) Another reason to switch to protected mode is better performance. 32-bit operations in real mode require override prefixes that take extra cycles to execute. And I may be able to switch to faster but more memory-intensive algorithms in places where they make a difference (e.g., IP routing and the malloc() storage allocator). One drawback: DJGPP executables require a 386 or better. Personally, I just don't see this as much of a problem nowadays. Those with 286s can always continue to run Borland-based versions.

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.

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 Given JNOS 1.10f running on a 386/20 with 16550s on all serial ports, what's the best strategy for serial port speeds to the KISS TNCs? We're looking at a switch that will have two 9600 baud TNCs, and probably two 1200 baud ones, as well as a couple of PI cards and an ethernet board. It'll be a busy machine... To reduce latency, we would want to run the ports as fast as possible, at least 2x the radio speed. But from an interrupt and system loading perspective, are there other considerations? In particular, would we be better off running the 1200 baud TNCs with very fast serial speeds? Or should we keep them at 2400 or 4800 baud? I guess the real question is whether the system and UARTs will be happier with fast but infrequent bursts of data, or with longer but more constant ones. Any ideas?

To: tcp-group%ucsd.edu@bbs.ve3rpi I recently received a response to my request for Windows based smtp/nntp mailers which would work with JNOS (I'm using v110b), pointing to gmail.exe. (gmail.zip at ucsd.edu) The version of gmail.exe which I downloaded (206336bytes, 2/27/93) had a couple of problems. The program would not delete mail files when requested, and an options menu selection "preferences" was not operational. Also there was no current help file, as indicated in the enclosed readme file. 1. Has anyone had success running gmail? Is there a more current version, or additional information which would assist in getting the version which I have operational? 2. Are there other Windows based mailers which work successfully with JNOS? If so what are the anonymous ftp sites? 3. I am posting this to both tcp-group and nos-bbs in hopes of a more complete response.

I assume it's a jnos problem. the network looks like: (A) Linux 1.1.37 ====ether==== (B) JNOS 1.08c ----+ 56kbps packet (D) Linux 1.1.47 ====== (C) Linux 1.1.47----+ In a nutshell, I had to change the mtu on (D) to 576, even though JNOS was set to 1500, just as all the other machine mtu's are set to 1500 (both for ethernet and 56k packet, it's all mtu of 1500). (A) can talk to (C) fine, but if (A) talks to (D), output from large bursts of data ends up hanging the connection. ie I can do ls OK in a small directory but it hangs in a directory with many files; ftp works for tiny files but hangs on 1k files. I *know* the mtu is set to 1500 on the jnos PI2 driver, unless jnos is only pretending to set the mtu to 1500. I also don't know why (A) to (C) works, if it's indeed an mtu thing. --------------------------------------------------------------------------- BogoMIPS Research Labs -- bogosity research & simulation -- VE7JPM -- jmorriso@bogomips.ee.ubc.ca ve7jpm@ve7jpm.ampr.org jmorriso@ve7ubc.ampr.org --------------------------------------------------------------------------- ------------------------------ Date: Tue, 20 Sep 94 14:08:55 BST From: Martin Lines Subject: SCC Testing To: nos-bbs@hydra.carleton.ca, tcp-group@UCSD.EDU Hi, I have just built an SCC and was fooled by the testing method described in the accompanying documentation. The document describes how an SCC card without modems can be tested by watching TXINTS increment when a connect is issued on one of the scc ports. I tried this and nothing happened. I then spent a while checking the board etc but everything appeared ok. Then when looking a SCC.C and SCC.H I realised that the system works in CSMA mode by default. This meant that as DCD was floating (ie no modem connected) the Transmit would not take place. Simply issuing the command param 5 1 turns on full duplex operation and off went the TXINTS nicely. Having got a working scc i can now turn to modems......

Some other minor bugs are fixed and system stability improved, memory leak IS gone! However this is only compiled with Borlandc C++ version 2.00 i cant confirm or test any other compiler and the performance of W-NOS with other versions of C++. Later today i will upload 2 .exe's one with just ASY and the other with SCC all services included, in both. Also packet drivers. file names: wn940921.zip = source's wn940921-asy.exe wn940921-scc.exe No Warrenty given std disclaimer stands. Barry gm8sau.dc0hk and the team.
