Networking / Re: VNC to Ubuntu LTS
« on: May 03, 2024, 10:28:57 am »
Once I've VNC working to my NAS I think (Debian) but just checked, does not work anymore. I usually connect via RDP cause I can select the screen resolution I wanna see on the host not dependent on the physical setting of the guest. Copy/paste works too. Only drawback is the rectangular cursor shape background.

Anyway I think you need X11 for VNC and RDP instead Wayland. I've not very much experience with Linux but what I've read and tested a while ago is - VNC/RDP does not work with Wayland. Maybe this is not true anymore though. Just a hint for start searching. Probably you need to add your user to some 'allowed users' file too for VNC (as it is with RDP).

Speed tests with SSDs vary on my system. I've tested with -
Samsung SSD 850 PRO 256GB
Samsung SSD 870 EVO 2TB
Samsung SSD 860 QVO 1TB
Crucial CT500MX500SSD1

It's sometimes not clear why copying from one SSD to another is faster with some setting while it's a bit slower with another target or source. I ever thought the maximum throughput you can get with an OS/2 system is copy from CLI cause a GUI program with progress indicator will always lower performance (the progress indicator needs to be update while CLI copy only waits for disk to accept new data, CLI does not even check CTRL-C). To my findings this is still true with disks although now LCMD comes very close to CLI. But in the last months I've even found scenarios where copying with LCMD is much faster than CLI copy (which TTBOMK uses 4k fixed buffer).

You may think copying with LCMD should be faster when not much else is running at the same time. But I've even scenarios where copying is actually a bit faster when LCMD lost the focus and some other heavy task are running. Once I even need a reboot to get the copy speed from/to a specific source/target to the level I'm used to. It was about 20% slower for unknown reason before.

Bottom line is it needs a lot of tests to get reproducible results. In most scenarios you can't get the same full speed with LCMD than with CLI but we are very close to that. Facts based on my tests for single big files are -
- Samba is way slower than ftp (more than 1,5 times slower here), both via netdrive *)
- for SSDs and harddisks LCMD is not exactly as fast als CLI copy but very close to it
- Ramdisk is way slower than SSD or harddisks (JFS is faster than HPFS but still 3 times slower)
- Peak values may be very high cause of SSD (and JFS) cache

*) Samba is way faster than FTP with a lot of small files I think because of it's directory caching which FTP is missing

I've it in that order and it works. I've used serial devices on this system since ages. Both the original ones (COM1: COM2: on the standard addresses with PSCOM) and USB converter devices. Mind the PL2303 device lines which are now remed out. I needed to load it 4 times to use the up to 4 attached USB converters. Since about a year the usbcom.sys (v12.13?) from Davids package work with my devices. And usbcom.sys is now loaded only once in contrast to the PL2303 driver.

Code: [Select]


REM ! DEVICE=P:\util\USBCOM_PL2303\usbcom.sys /V /M:1 /N:COM5 /Z
REM ! DEVICE=P:\util\USBCOM_PL2303\usbcom.sys /V /M:1 /N:COM6 /Z
REM ! DEVICE=P:\util\USBCOM_PL2303\usbcom.sys /V /M:1 /N:COM7 /Z
REM ! DEVICE=P:\util\USBCOM_PL2303\usbcom.sys /V /M:1 /N:COM8 /Z

When I attach one or more usb converters 'mode com6:' 'mode com7:' shows me the attached working devices. I need the /Z option cause I don't use CTS/RTS/DTR/DSR (?) handshake I guess. But with a real modem attached I think you should enable hardware handshake. Anyway as long as 'mode comx:' does not show the device working you don't need to play with any higher level program. Maybe it's necessary to attach a working modem to recognize the handshake lines for that. So maybe testing with /Z first.

Btw. when I played the last time with modems probably more then a decade ago I can't get my US Robotics 56k to work again after it was laying around for 10 years or so. The even older ELSA 33k on the other hand did work with PMFAX.

I understand the problem for people with high resolution screen usually found in modern Notebooks. But I think it should be possible with current version to set all controls to the needed bigger fonts. This setting should survive restarts. I'm I right Martin?

If yes I think it's not high priority to invest much time in this and so there's nothing which I can do in near future. F.i. the (rare) crashes and some leak in currently unknown system resources are more important IMO.

I just wait on Martins response and if there is no real show stopper (f.i. some controls can't be changed to usable fonts) I'll create a ticket with all the valuable infos from Rich. Maybe some time someone finds the time to make a more elegant solution for that.

Programming / PMPrintf package v2.80 and PMPrintf_abtrace code samples
« on: April 21, 2024, 07:43:39 pm »
I've packed together my latest code base of PMPrintf and packed it together as v2.80. See

PMPrintf sends standard printf formatted debug messages into a queue. If the PM viewer application (PMPrintf.exe) or CLI logger (PmPfLog.exe) is running it will display these queued data. Otherwise they go to NULL. Log files can be written to disk in parallel too.

If you never used PMPrintf I strongly suggest looking at the code and usage samples at These samples loads pmprintf.dll dynamically if it is available on the target system. If not your program will normally run and your debug messages goes to NULL. There is no need to make extra release and debug builds. The small overhead will be negligible most of the time. A programmers life can be so easy :-).

Have fun.

Oh, I never used these setting page by myself. In fact I took the usual OS/2 way - drag/drop a font from the font palette to the desired place. I think I remember all these dropped fonts (and colors, and background colors) are saved and restored. So I think you only have to drop your desired fonts on the different controls and you're done. Does this not work for your on one of the controls?

Though I for myself rarely had the need to change my fonts the last decade or so as I still use monitors with 94-105dpi (most of the time).

I've just uploaded v1.08.02 at

From the Readme -
Code: [Select]
Change History:
20240416 v1.8.2
- Improve EA handling routines to reduce memory leaks and silent crashes
- Fix TRAP 000e in JFS while copying >69000 files. Hint, please use latest ArcaOS (kernel, JFS, ACPI 3.23.17, ...)
- Removed gl16os2.dll dependency (link .obj into .exe)
- Handel out of memory conditions more gracefully
- Added abtrace for logging via pmprintf.dll (if available on target system)
- Improved build cmd files to break on error (ERRORLEVEL handling)
- Tuneed lxlite options to not remove bldlevel info
- Change to David G. icon files (no clue where they are used)
- Again tuning of dynamic copy buffer size adoption (even more speed on my system :-) )
- Change icons to the ones supplied by David G. Thanks for that although it's not clear to me where they are used.
(- Disable integrated exception handlers in favor of exceptq) reverted back
- Disabled ExceptQ handler as I can't get it to work in conjunction with lcmds own handlers

Bug reports please here -

Of course I'll keep reading here as well from time to time. Have fun.

Btw. I've a really hard time to track down and reduce this terrible JFS traps when copying a lot of files. It seems to me that JFS still does not touch some memory pages when feed with >4k buffers some times which I guess leads to these 000e traps. Combined with the memory leaks which LCMD suffered when lot of files where copied I had uncountable crashes with long chkdsks afterwards. Now the I reduced memory need for extended attribute handling I can't see these memory leaks anymore with above512. But on some scenarios LCMD still seems to eat up some system resources which report out of memory. Closing LCMD will recover from such situations now.

If you encounter hangs of LCMD you may look at the lcmd.log file in the directory of lcmd.exe. F.i. tail -n 50 lcmd.log will show you the last messages which usually shows some exception infos. For this you've to enable 'Debug' or 'Test' in Help - Debug - Options. Be aware running LCMD with 'Debug' for a long time or while copying huge amount of files let lcmd.log become very big in minutes.

Btw. if you've pmprintf.dll on your system PmPrintf.exe will show you these messages from LCMD with 'Debug' or 'Test' enabled too.

Networking / Re: Netdrive and ArcaOS
« on: April 03, 2024, 02:21:36 pm »
Is the version of NetDrive included in ArcaOS the full version,
No. Works only with the Samba plugin AFAIK. Maybe ISO too?

If no, can one install the conventional netdrive without creating conflicts?
Yes. You can install it in parallel but you may have to redirect the settings in config.sys and tcpexit/b4... or whoever ndctl.exe is started from.

Programming / Re: ArcaOS - Recreate a complete build environment?
« on: April 03, 2024, 11:43:18 am »
because I like to keep OS volume and application on separated units - albeit logically, or even better on separate drives,
SET UNIXROOT=x: where x: is your separate drive. It's that easy with BWWs rpm packages.

Stupid me didn't think about this.
Thanks a million!

Of course you've to decide this when you install ArcaOS as a lot of things depend on the files there. I don't recommend moving it afterwards.

Just for completeness in this valuable thread, we also need -

yum install binutils

and probably
yum install os2tk45

Applications / Re: XWP v1.0.16
« on: March 29, 2024, 08:05:51 pm »
but it does not work for me
Turbo Folders enabled? I seem to remember this is necessary for the hotkeys in XWP. But it's so long ago that I read the docs about that.....

I remember a had to read the docs a few times until I understand what it does and how to setup up. Though I'm not sure it can do what you need.

Setup & Installation / Re: Ecomstation 1.0
« on: March 29, 2024, 09:48:01 am »
It is not for sale anymore and the company does not exist anymore. Why there are people thinks this is piracy ? This is abadonware . Not for sale anymore . I try this system on a old pc . But without a key it is total useless. And i do not buy a old operating system. A shame to give no serial key for a old system .
It's legally not allowed to give away a personal key for this product. Period. If someone decides to not play to the rules so be it. But you shouldn't complain when others respect the laws. Maybe someone will sell you his license? It's legally allowed to sell a software license you bought in the EU. So if someone would sell you or donate to you his license ....

Storage / Re: How to properly setup a working FAT32 USB stick?
« on: March 06, 2024, 04:14:31 pm »
Thanks Dave.  Why is everything so much more complicated with Arca, ,are they trying to kill off OS/2?

Complicated compared to what? On Linux you don't have drive letters so not comparable. On Win you need to set the letter in "Datentr├Ągerverwaltung" (English name?) too if you wanna have the same fixed one. So no difference.

What's Arca, ,? ArcaOS you mean I guess. Or does have the two commas a special meaning? I don't see any difference here compared to latest OS/2 version.

Utilities / Re: vncserver setup
« on: February 29, 2024, 11:21:54 am »
Any entry in popuplog.os2?

I'm running vncserver/client since many years. Think some version from last year or so. No problem here. Wild guess, you miss some dependency dll. Hence looking into popuplog.os2.
