(But I've now got: "PPP design & debugging" James Carlson). I'll try to expand Edgar's PPP.Tool -- renamed to PPP.Text . I believe that an understanding of S3 multi-tasking is needed to understand the symptoms which I described. I intend to provide a full explanation of the fault which IMO must include considerations of multi-tasking, so I'd appreciate answers to these questions: 1. does S3 multitasking use an equal time slice for each task of the 'circular sequence' of tasks ? 2. How could the Ctrl+<break> (TRAP 13 Keyboard interrupt) allow the 'hung state' of the PPP' to release'. 3. any other descriptions or pointers re. S3 multitasking. The multitasking aspect is IMO more interesting than fixing the seldom occuring PPP problem. -- Chris Glur.

BlueBottle: ETH Oberon / Aos 29.01.2003

Hi, If Kernel.Log window is opened by System.OpenKernelLog command and closed from its menu bar [Close] button, after a Desktops.Recall or System.Recall command the menu bar of Kernel.Log is not shown. The problem seems to be in Aos.System.Mod If the following line in System.OpenKernelLog procedure OpenText("Kernel.Log|System.Close System.Copy Edit.Search System.Clear", log, TRUE) is replaced by the below line OpenText("Kernel.Log", log, TRUE) problem disappears. Best regards. Necati.

AsciiEdit for Bluebottle (demo).
by rotaru＠centrum.cz 20 Feb '03

You can get it from www.webpark.cz/vrotaru/pl/ae00.zip It is very minimal and it is work in progress (if I will have the time, something which is rather problematic). The cut&paste code is just a temporary hack (It even uses AosExample6.Mod), the caret code is not perfect and there are some subtle inconsistencies with cursor moving at beginning/ends of lines. Still, it may be used for small editing tasks such as adding a quotes to AosQuotes.txt or making changes in Menu.XML/AosConfig.XMl.

Pieter, thanks for removing the restriction to 700 kB chunks in Miscellaneous.SplitFile/JoinFiles. The command is much better now for moving Docu.zip to a non-network-connected machine and for backups. ... Peter E. http://carnot.pathology.ubc.ca/

Re: [Oberon] Version control
by Edgar＠EdgarSchwarz.de 18 Feb '03

Hallo Felix, > Does anyone of you have an automatic version control for Oberon (with > logging in / out etc.)? I just uploaded WebDAV.0.5.0.Zip (Using WebDAV itself) to "http://ketchup.ethz.ch/dav/WebDAV.0.5.0.Zip". Don't trust on it staying there. It just was the easiest place to upload at the moment. Also a test :-) A trial download with Mozilla under Windows was successful. So as long as ETH doesn't need the machine for other purposes and the WebDAV server is running you could give it a try. It's a simple server implementing some methods of RFC 2518 WebDAV (MKCOL, DELETE, PROPFIND) and RFC3253 DeltaV (VERSION-CONTROL, CHECKIN, CHECKOUT, UNCHECKOUT, REPORT, BASELINE-CONTROL, UPDATE) at least as far as necessary to do some versioning. The client has a command interface at the moment. Sending it's output to System.OpenKernelLog. The repository is maintained on a FAT Partition on ketchup.ethz.ch using VCS. You must use BlueBottle because the RFCs use XML. Also I wouldn't try to use client and server with other DeltaV clients and servers at the moment. This evening I plan to cleanup and extend the docs and upload it.

Mail.Panel: LeaveOnServer
by peter_easthope＠gulfnet.sd64.bc.ca 18 Feb '03

18 Feb '03

Oberoners, Currently I have ETH Oberon / PC Native 24.08.2002. Oberon.Text has "LeaveOnServer = No" and the similar setting in the Mail.Panel is not checked. I am almost certain that with an earlier release, messages were deleted from the server. Yet messages now remain on the server after being retrieved. Does this feature not work or am I just being dense about something. Thanks, Peter E.

Compiler/runtime system bug?
by rotaru＠centrum.cz 17 Feb '03

17 Feb '03

User Feedback Name: Vasile Rotaru Email: rotaru(a)centrum.cz Version: Bluebottle OS (7 january 2003) Problem: Probably a compiler/runtime system bug. I am working on a small ascii/plain text editor under/for Bluebottle (Aos). For the moment it is even less than a demo. My problem is that I can run this demo only once. After first run every attempt to run it a second time or to run a compiler locks the system. But if do not run a compiler or the demo for another time I still can edit, open and store files. And I can reboot the system. I've tryed to run this demo (SmallEdit.TestT) from the menu panel (the Oberon not being running, and not even loaded). I runs Ok, and seems to terminate cleanly. But this is all.. Any attempt to run anything else, say Bunny, or Object Tracker locks the system. And I have to poweroff the machine to make it work again. Now there are some details. I have tryied to comment out parts of the code to see if I can localize the problem. In the initialization code of TextWindow object this line seems to be the guilty one: NEW (formatter, columns, rows. ...) It alone is enough to lock the system. No more call of formatter methods are needed for this locking up. And in the formatter initialization code this line make problems. NEW (buf, (width + 1) * height)); If it is commented out the "symptoms" are not seen anymore. But, |buf| is POITER TO ARRAY TO Cell, and Cell is a plain RECORD. And when I have changed the |buf| to be buf : ARRAY 81 * 32 OF Cell; the system has stoped locking. Well, If NEW is a dangerous operation in BB you should at least warn the people :). It is rather interesting that when I create and use a Formatter object directly (in SmallEdit0.Test...) the system does not lock up. You can found the incriminated files at: www.webpark.cz/vrotaru/pl/se.zip And I'd like to know which is BB policy about LF/CR/LF-CR problem. Which ``end of line'' is politically correct? I'm asking because some of the XML files in the distribution should be opened with EditTools.OpenAscii and some with EditTools.OpenUnix. And which is (will be) the canonical suffix of XML files, ".XML" or ".xml" ? It is rather confusing to have both. Vasile Rotaru P.S. Well I have changed the ``buf'' to be ARRAY 81 * 32 OF Cell; and I have continued to play with it. The test now runs smoothly (and ressembles more a text editor). But only if call it like this ``Aos.Call SmalEdit.TestT ~'' from Oberon. I have tried to run it from Menu Panel and after that start Oberon. For some reasons the Oberon starts in full-screen mode and traps wildly. I have not investigated this. May be later. -------------------- PŘÍLOHA O DANÍCH!

Chris & others, cg> ... the principle is similar - I think: cleaning up after use to allow the next user. Absolutely! cg> Interestingly, you previously wrote: >> ...

"Desktops.OpenDoc V24.Panel" >> gives this message. >> Can not open port, error = 1 I found that, assuming the port is available, the V24 panel can open it and issue the "ATZ" and "ATD T539..." commands directly. Also, the V24.Panel can store these commands in the drop-down menu to the right of the Log button. cg> Let's not just gloss over this, ... Certainly not! cg> V24.Panel expects to find the port closed when it starts/is-installed ? A reasonable assumption. Seems that any task which uses a port should relinquish it when the task is finished. cg> What are the multi-tasking implications ? A question for the experts. Patrik, Pieter, Thomas? I am just an amateur user. cg> 2. The dialer/ppp 'combination' does not close the port (which it used) at PPPMain.StopInst ? Why not ? Edgar might answer this best. cg> 3. What are the considerations when 2 tasks want to access the same serial port ? The general assumption seems to be that the first task gets the port and others are "out of luck". cg> 4. Where is the documentation re. 'installing'/multi-tasking for S3 ? The best I know of is "Chapter 15, Module Oberon" beginning on page 154 in Reiser's _The Oberon System_. cg> Personally I don't favour this empirical method, and prefer a well understood/documented theoretical model which can be analysed. Documentation could help. I am not clear on the rules for allocation of a port to a task. cg> Hacking down at the low level, without the supporting overview understanding is not recommended. I first need to get an overview. Likewise here. Still no report about discussion of PPP in the O'Reilly book on TCP/IP. This mailing list has enough readers. Can't one person find that book or some other in a campus bookstore? Regards, Peter E.

I'd appreciate some feedback to my perhaps wrong assumptions:- 1. V24.Panel expects to find the port closed when it starts/is-installed ? This could be changed, by checking for open first ? What are the multi-tasking implications ? 2. The dialer/ppp 'combination' does not close the port (which it used) at PPPMain.StopInst ? Why not ? 3. What are the considerations when 2 tasks want to access the same serial port ? 4. Where is the documentation re.

As I previously wrote: with the change of weather (line conditions) the error no longer shows. Hardware modifying the line to bring back the error is a last resort - when I have time !
