Porting WebDAV to BlueBottle for Windows
by John Drake 18 Jun '03

18 Jun '03

Hello all, Well I've finally done it! WebDAV running under a Windows version of Oberon! Actually I haven't tested it yet. Just happy to get a clean compile. Note that it doesn't "compile out of the box". I had to copy the following files over from the "native" version of BlueBottle: AosDNS.Mod, AosIP.Mod, AosNet.Mod, AosTCP.Mod, AosTcpServices.Mod, AosUDP.Mod, TFClasses.Mod, TFFilter.Mod (Note: I've noticed that some of the above files have already been copied into the latest version of BlueBottle for Windows). Also I had to copy over the XML modules. And I had to copy the procedure AtomicInc from the native "AosKernel.Mod" to "Win32.AosKernel.Mod". Anyway, so far so good. Regards, John M.

monitoring an RS-232 interface.
by peter_easthope＠gulfnet.sd64.bc.ca 18 Jun '03

Here is a rather unusual problem. I want to monitor the serial interface of an external modem. The approach I am considering is a generalization of that described in "http://www.oberon.ethz.ch/native/WebTrace.html" . In this case we need to monitor both sending and receiving lines. This will require a tee serial cable with the side branch dividing to two cables. One of these side branches needs the send and receive lines crossed. This special cable will be inserted between the modem and the server. Then one "observer" machine can be attached to each of the side branches. WIth this setup, one observer will monitor transmissions from computer to modem and the other will monitor transmissions from modem to computer. Perhaps one machine with two serial ports is capable of monitoring both lines. No doubt this would work with Unix but I have not tried running two concurrent V24 tasks in Oberon. Is such a technique described elsewhere? Any suggestions or improvements on my proposal? Thanks, Peter E. http://carnot.pathology.ubc.ca/

André & Chris, af> Here is a Bluebottle module for tracing. Thanks André. Now I really need to get a portable Pentium machine. af> The Bluebottle machine is an observer inserted between another machine and the device it is supposed to control, for example a box recognizing AT commands. Completely sensible idea which hadn't even crossed my mind. cg> I think Peter, and definately I, want to monitor what is really happening outside of the machine. Chris, my understanding is that the observer passes data through from one serial port to another, in both directions. Assuming the monitoring software is bug free, it does monitor all traffic on the serial line. cg> Where is the vital info about the cabling, which Peter raised ? The cabling is simpler than I described. Just one straight cable from modem to observer and one straight cable from observer to computer. A nice tidy arrangement, typical of Oberon/AOS. cg> To get an idea of the speed multi-tasking capabilities you may want a 3 ser-port setup - need one for the mouse. If the oberserver machine has two serial ports, a PS-2 mouse might be used. Regards, Peter E. http://carnot.pathology.ubc.ca/

Hello, It find sometimes in Bluebottle sources texts that look like preprocessor instructions ($IF ... $END). I can't find any documentation about this feature. Could anyone give me some links or explanations? Thanks. Gérard

Hello, I send this message to oberon-web(a)inf.ethz.ch but It bounced, so I decided to resend it to this list in order to reach ETH people. I am an assistant professor at Escuela Colombiana de Ingenieria (Bogota, Colombia, South America) and I am very interested in the sources of your early iimplementations of the Oberon System. Especially, the sources of DOS Oberon 386 System 3 version 2.0 by Andreas R. Distelli, Oberon V4 version1.4 for Windows by Mathias Hausner, and Oberon System 3 for Windows Version 2.0 ("Spirit of Oberon") by Hannes Marais. Are the sources still available? If affirmative, what is the proper procedure to obtain a copy?. Thanks In Advance Gerardo Ospina ps. I also have interest in other sources: DOS Oberon V2 version 2.0 and POWEROberon V4 Version ?? pps: The bounced message was. > Date: Mon, 16 Jun 2003 20:29:46 +0200 (MEST) > From: MAILER-DAEMON(a)inf.ethz.ch (Mail Delivery System) > Subject: Undelivered Mail Returned to Sender > To: gospina(a)escuelaing.edu.co > > This is the Postfix program at host medoc.inf.ethz.ch. > 'm sorry to have to inform you that the message returned > below could not be delivered to one or more destinations. > For further assistance, please send mail to <postmaster> > If you do so, please include this problem report.

Sorry for the wrong time stamp on several previous messages. (I plead hardware problems and lack of alertness.) Chris, cg> > "http://www.oberon.ethz.ch/native/WebTrace.html" . I've archived this. It's only about 10 lines. Is that right ? Yes. cg> "WebTrace" seems to be a poorly chosen name. Perhaps someone at the ETH can change the name to SerialTrace.html or such. cg> The serial port(s) only need attention when their FIFO (buffers) are getting full ... Has n-o got the ability to interrupt for modem or mouse ? No. There is only a simple event loop. I haven't studied V24.Mod but judging by the LEDs on the modem, receiving and transmitting rarely persist very long. So the keyboard and mouse shouldn't need to wait very long for attention. So long as the event loop isn't bogged down with other tasks, Oberon might keep up with two serial lines. Also, monitoring of a serial line needs no mouse and keyboard input until you are ready to stop monitoring. A delay in response to mouse or keyboard should not be a concern. cg> Older machines had smaller buffered ser-chips and would be more likely to 'overflow'. Seems best to just set up available hardware and try it. Why not? cg> The whole business of how (normally) the ser-modem is given and releases its ser-port, is central to the ppp-bug which I'm investigating, and where readers 'look the other way' when I ask questions. =:-( These are unusual problems; solutions are not immediately evident. Persist. cg> What is the serial port speed setting for the mouse ? Check Input.Mod and modules it imports. Presumeably the program for AOS which Thomas mentioned would have the advantage of integrating the received and transmitted data better than simply using two V24 tasks. My limitation is not having a portable Pentium machine for Bluebottle. P.S. to original message. Rather than make a tee cable with a side branch splitting into two I should just take a ribbon cable and install two additional connectors between the ends. A straight modem cable can connect one of these connectors to one serial port. A null modem cable can connect the other connector to the second serial port. Thanks for the ideas.

tf> There is such a program for Aos/Bluebottle. You can link the watch computer between the modem and the control computer. I'll have to search for the program if you are interested. That would be a help thanks. Perhaps it can be posted on the FTP server with a link from a Web page. Chris G. and a few others might also find it useful.

XON/XOFF Ie. the file of 371K now has 23 'chapters' !! The index looks much better in colour. I spend half an hour a week average investigating this 'dog'. As I recall the condition applied also on my other scrap-box. The last idea was to send hex11 to the modem (the default XON?XOFF). But I can't because (as has been disclosed during this investigation) V24 can't be run until ppp releases (apparently the port). And if I Free ?pppMain? as indicated in my previous post, I need to reboot, and the problem is gone. And now I remember that I have recorded the various status register values of the ser. chip, when in and out of the 'problem-state'. I.e. the problem occurs before the modem - so XON/XOFF would have no effect. Or does the 'ready' line(s) from the modem effect the ser.chip status ? Probably. But probably I checked this by removing the modem ? This is the kind of 'exotic' thinking that is required:--- " The other box had a period when (depending on the weather) n-o whould not get dial tone, although the same hardware under DOS and linux would. This suggests a timing issue. My second modem required extra " ATX" to recognise dial tone. This is quiet common in s. africa - apparently the telco conditions." The person who can immediately see the cause of the current bug is the person who understands the multi-tasking of n-o and how the Ctrl/Break effects things, down at the machine code level." -- Chris Glur ---------------- addition to second post:- I've: * conected another machine with V24 in place of the modem; it looks OK except that the <line terminator> is 'problematic' with V24. I think modems want CR and n-o V24 wants LF. * confirmded that the ser-port status regs are influenced by switching the modem on/off. It's a FSM, in that the ser-port status regs are changed by READING. ---- It's time to look beyond simple explanations: think of multi-tasking effects. Why does Keyboard: Ctrl/Break 'unlock' the problem ?

Hello, First of all, I must say that the new version of Bluebottle is very pleasant to use, more the previous one. Thanks. I get a problem when opening Oberon.Desk with Desktops.Open. A page fault trap occurs (-14). What happens? Wrong versions of some modules? Gérard
