Re: [Freedos-user] [Freedos-devel] FreeDOS 1.2 and 2.0 roadmap discuss ion
So Bertho was volunteering or did I misunderstand his message? I've come to be a fan all kinds of virtualization, VMs, appliances The android-x86.org project re-compiles Android for x86 which I run on Windows 8.1 in a VirtualBox VM. It is fast enough. Most of Android works as it does on my smartphone. I like running my Apps on my laptop while I'm doing my software development. The data syncs to my phone. FreeDOS could be valuable packaged as a porable VM appliance. That VM could be packaged with simulated storage, USB linkages, printer port translations, display adaptations, and a VM control panel. VMs are what Amazon Web Services, AWS, is. A FreeDOS appliance when setup for that environment can be shared and copied at will. If it crashes, it can be recovered in seconds. Local printing from the Internet is available already. These two examples show that VMs can be expected to run any older useful software on its original OS. As machine and OS emulation progresses this can be expected to be common. That reminds me schedule to build an AWS version of a DOS business software package. -- Dive into the World of Parallel Programming!

Re: [Freedos-user] I'm back!
Jim, Good for you. I've just started work on finishing my Aerospace Engineering degree. That's right I'm a Rocket Scientist. Still works at a party. Since you now have major cred on usability maybe you might find a way to get LINUX on that righteous path. KDE, Gnome, and the rest are beat by Apple's environment and wait for it... yes even M$-Windows is a bit better than the LINUX contenders. I'm embarrassed to say it. DOS? Well I guess it's just DOS as always. I'm looking to run DOS with an application as a cloud appliance. Appliance really means Amazon Web Services or Google's compute product, Such old DOS programs can now live forever. The Federal Aviation Agency, FAA, used emulation of older computers, not DOS, to run older air traffic control software. They had tried to rewrite that software but seemed to keep failing. It appears that old software ran for several years before replacement. . Cheers, John S.

We certainly need it. Open source software tends to be well crafted under the hood, but problematic for end users who have to deal with it. I was just in a discussion about the issue on another list. And both Linux Journal and Linux Voice said they would like to run a version of my article, so I'm writing separate versions for them. The SourceForge folks also asked me to write an ongoing series of articles for their blog, about usability in free / open source software. Excellent. I think versions of the audience aimed at general readers are needed. A paper written as part of a thesis requirement is a specialized beast. And a blog series for SourceForge would be a boon, if nothing else to get across the notion that mere mortals may have to use the code.

If you are capturing timing events you really only need to respond to an event and store a time for later processing. I usually use a microcontroller and write a routine around its interrupts so that it can respond easily down to microseconds and give good resolution (this has been mainly for medical projects that are not particularly high frequency). So you have the interrupts running code real time, and the normal loop crunching the numbers and providing output. Real time output can be set up very much like above, where the internal counter triggers the interrupt which outputs a value. Say you want to output a particular current at a particular time. Servo is much harder because it must respond to an input, and process it to give an output, at a defined frequency response. This is usually demonstrated with the balancing hammer where the servo balances a hammer on its end. There are systems that achieve this even if the hammer has a jointed hinge in the middle. I have even heard of it being done where there are two joints. This is a bit like trying to reverse a 3 bogey semi-trailer up a country lane at freeway speed. When you see Windows attempt the hammer demo you can see that every keyboard press or mouse movement causes instability, and opening a browser can make the hammer fall over. Often a simple microcontroller can beat even a really fast powerful computer, mainly because you can use the interrupts which I have found are almost impossible to get at in computers. Real time simply means guaranteed to respond to an external event within a specified period. What time period is required? But on modern hardware, other time-critical programs that will carve out slices of CPU time are likely a Who cares? issue. Commonly used hardware is orders of magnitude faster than the machines DOS was made to run on, and there are cases like games where you might specifically *want* to steal CPU slices, because otherwise your game runs *too* fast and is unplayable. . I have had to do this once, when writing an assembly code driver for a digital rotation encoder. The read cycle had to be slowed down by a specified number of NOPs to allow the register to load. The problem is that when a program is monitoring response devices such as the mouse and keyboard and presenting an animated display to the user, even a millisecond lost to some other program is a disaster. As I can often see the system blink on modern PCs running Windows and even Linux, I'm reasonably certain that I can't trust them to be accurately recording reaction times. One of my colleagues thought that she had solved the problem by buying an expensive test battery until I showed her the uncertainty factor that came with every response recorded. How accurately do you *need* to be recording reaction times? For that use case, I'm not sure I'd try to run DOS on top of Linux, even with a Linux version modified for RTOS usage. The best option might be custom monitoring software running directory on the RTOS, without DOS in the loop

Re: [Freedos-user] hard drive question?
Karen, There must be a program you need to run using a DOS environment. Am I right about this? If so is it a well known package or a custom software package? Some of older DOS software packages required a more traditional DOS filesystem like FAT-16. The decision as to which filesystem to use is sometimes imposed by an application program. An example I've encountered was a custom Clipper database software package that is insisting on a less than 540 megabyte partition. Why 540 Megabytes I don't know. Just to be safe I found it necessary to limit the partition size to 510 Megabytes. As I understand it, the original Clipper compiler was built using Microsoft C 5.1. Many add-on libraries used that same compiler and its libraries. Somewhere within that combination, partition size limits were imposed on the run-time program.

Re: [Freedos-user] (no subject) - dos printer network in vmware
Eric, You probably already know this technique inside the Windows standard SMB on top of NETBIOS over TCP/IP. I've used network sharing to provide an LPT1 printer to the a DOS program. It was a Windows XP Home Edition with service pack 3, sp3, installed. This was outside any VM player's environment. Once the printer shared the next step is to assign it to intercept output going to LPT1 like this NET USE LPT1 \\computername\printername ...it works most of the time. I've used this with a CA Clipper exe program which has a fussy library that can, not always, try to access the hardware directly. Clipper is a 1990s compiler for the dBase language system, files usually had a dbf extension It can be replaced with the harbour-project.sourceforge.net hosted to DOS. There is a xharbour project and a Flagship product and some others. I can imagine you can use a VM which can share a printer via SMB sharing using the VM virtual network inside the hosting computer. Then use the same NET USE assignment Cheers John S Wolter - Mailto:johnswol...@wolterworks.com - USA, Eastern Standard Time, -5 GMT, -4 GMT DST On Wed, Sep 19, 2012 at 7:05 PM, Eric Auer e.a...@jpberlin.de wrote: Hi!

The entire time to watch that 37KB file scroll by is around 7 seconds, or about 5200 chars per second including the scrolling time. (The time to scroll is longer than the time to print chars.) Is VirtualBox slow because of what you are doing in those batch files, or is it slow no matter what you do? For example, try my little test there and see how fast it goes. We need to isolate what is causing your slowdown. And please try this with both TSRs and device drivers loaded and without so that we can see if it is a TSR or device driver problem. I have never heard of something that slow before in VirtualBox. As an alternative, you can try VMWare to see if it is something specific to VirtualBox. (I have found problems in VirtualBox before related to programs that reprogram the programmable interrupt timer. The mTCP PING program exposed it. It only affected PING while it was running.) RAM should not be the issue. But laptop hardware tends to throttle the speed if it is not plugged into the wall and allowed to run at full speed. I doubt this is your problem, but just in case, please clarify that the laptops are on wall power and are set to run at maximum CPU speed while on wall power. FDAPM and APMDOS are only introduced as a way to conserve battery power or reduce electricity consumption when used with wall power. Which reduces heat, which is always a good thing ... mTCP requires its own network adapter and can not co-exist with MS-Client. The same is true for WATTCP based applications. If you are trying to use both the MS-Client and mTCP or WATTCP programs at the same time on the same adapter then you need to add another adapter. Each of those programs assumes that they own the adapter and will fight each other in fun ways.

[Freedos-user] FreeDos in VirtualBox not a sure thing
I spent four days getting FreeDOS to work as a guest OS inside a VirtualBox machine. The path to success was a rocky and time consuming trial and error process. Once the particular console program was running it was not very fast. The customer deemed it to be usable. Later in the day the customer cancelled a small DOS software install in preference to a larger native Windows 7 development. The customer had decided to purchase an older computer to run the DOS application from hard disk. It amounts to a lost increment of business for myself that is not significant. This situation indicates to me that efficient execution of FreeDOS in Virtual Machines must be made to be transparently easy. VMs are a way to make FreeDOS available as 16-bit support withers away. The industry leader's 64-bit OS does not support 16-bit DOS programs directly as in prior versions. Open source software developers, unfairly, have more pressures on them to prove the results. I've seen the form discussions as do others about run-away keyboard polling and other such issues. Solving these nagging issues may not look to be glamorous but can swing perceptions of FreeDOS substantially. There are commercial utilities claiming to control problems but I ask are there equivalent features or settings within FreeDOS? FreeDOS did not create these wild-hare programs but is being painted with their behaviors. It is FreeDOS's burden in life:(i.

Re: [Freedos-user] FreeDos in VirtualBox not a sure thing
No Name,
Are you one of the developers?
Can you describe what exactly were the problems?
No. It is not clear if the issue is within FreeDOS, the applications
program, the VM, or VirtualBox itself. It is good that FreeDOS and
VirtualBox have source code. The applications program does not.
As for myself I've had no issues with getting FreeDOS to run in VMWare
player, QEMU and VitualBox. I used the original FreeDOS 1.0 install and
have manually updated the kernel since then.
Here is the page I used as a starting point.
http://lazybrowndog.net/freedos/virtualbox/ The iso provided has a
configuration and FreeDOS setup. I believe is uses the 1.1 disk.
I used Host-Only Ethernet adapter instead of the bridge adapter for this
local application program. This usually makes sense for local installs
that are not using network features. Selection #4 is what was needed. I
used that after using other cookbook only solutions did not work.
As for VirtualBox specifically, it will run a VMDK file so I use the same
VMDK file that I have created for VMWare - no problems. For daily use I
use VMWare under Windows XP, under Linux I use QEMU and sometimes use QEMU
under Windows in special situations. I almost never use VirtualBox but
fired it up just now after your posting.
It appears you do not use VirtualBox, preferring QEMU and VMware.
VirtualBox is not in the top three.
So is the problem simply eating up processor time?
Good question.
FreeDOS from an OS point of view is actually pretty good - there is an
option in the kernel to HLT during waits for keyboard input (IDLEHALT=-1 in
FDCONFIG.SYS) which I have used and recommend.
I've not found that in the manual. Let me know where those are documented
But the real problem is the applications. For example FreeDOS EDIT.EXE is
a terrible offender. I modified it for my own use to throw in a few HLTs
and now it works great. People will talk about making applications FDAPM
aware and using the mutliplex interrupt - I personally don't do these
things - I make sure that the application in question is doing a HLT
frequently. (For those who think the computer will lock up the HLT
directive halts the processor until the next interrupt... not forever)
Yes, I called them wild-hare programs. My point is that even though
FreeDOS is not cause of the issues it is time to add some ways for it track
to the executions and keep things under control. A keyboard port should be
controlable.
So you must customize every application the user will touch.
If you have the source code, this should be easy. .. look for processor
loops and put in some HLTs.
If you don't have the source code you are going to have to run thru a
debugger and find where the program is looping ... break the debugger when
windows says you're at 100% utilization, should be easy to figure out. Then
you need to patch the BIOS routine, DOS routine or do a binary patch to the
application.
Basically we have no idea what kind of loop or polling your application
might do. There is no guarantee that
your app is calling the OS or BIOS on these loops so the operating system
will not be able to fix your problems.
Here's an example:
I see it will have to read the code. I wonder if a Sleep or Napping
function is a better approach. This might be an event awakened when the
subscribed service asks for service with a callback. HLT, halts the
processor as you pointed out. The subscribed service can be adjusted in
sitsu to get the desired level of attention for say the keyboard.
Original program:
while (hw_not_ready)
{
int hw_status = read_hw(); /* read_hw could be anything, like inportb()
*/
if (hw_status == GOOD) hw_not_ready=FALSE;
}
Better program for a VM:
while (hw_not_ready)
{
int hw_status=read_hw();
if (hw_status==GOOD) hw_not_ready=FALSE;
else delay_a_tick();
}
bios_clk_ptr = MK_FP(0,0x46c);
void delay_a_tick()
{
long ticks = *bios_clk_ptr;
while(*bios_clk_ptr == ticks)
_asm hlt;
}

[Freedos-user] Processor overheating under DOS
If the processor overheats with other OS's like IBM PC DOS(any version) then could it be the hardware. I'm guessing obviously. I just can't remember an old DOS portable(transportable) like an old 15 kg Compaq that would overheat this way. I've built power-supplies from parts and I've never seen a situation where a CPU would overheat under an particular OS like FlexOS or MS-DOS or FreeDOS. I keep thinking it's related to hardware. Someone please point me to an online article that would support this idea of an OS specific overheating power-supply. Are there Dust-Bunnies inside the power-supply? Is the p-s fan working? Is there a CPU fan and is it working? Is the p-s broken? Do you have a volt meter? If so check the p-s outputs. Is it grounding on the chassis? Is it arching to ground when the p-s warms up?

Re: [Freedos-user] Processor overheating under DOS
Christian, It basically is related to current system board design and therefore the dangling question is what aspect of design. What if anything has changed since that time? Are you referring to libraries, the CPU or something entirely else with this question? I'm referring to the CPU and I should include the the bridges. Does anyone among those on this form know something about or can offer links to an introductory discussion of current system board design? It is clear that thermal design is part of board design. I recommend not to run any modern system without FDAPM or idling applications. Thank you for the extended discussion of keyboard input. I can see the CPU is looping intensely. The roll of FDAPM based on your description needs some examination. The source code for it is the place to start. It may be productive to communicate with the maintainer of its code. John S.

Re: [Freedos-user] Some fix for Windows XP FreeDOS printing delays
Eric, Thank you for the PRN information. How would PRN behave in the situation that strings are output but no End-Of-Print-Job is sent? Well on real hardware it would depend on the printer. Some printers have some timeout and if nothing is sent for a while then they print the part of the print job that they already have received, possibly leaving part of the page empty but still ejecting it... Today I'm programming an HP P4015 to get the DOS output formatted. It appears to have a way to program that timer. Knock-wood. I think the Windows story is different - it tries to bundle your DOS print data into a print job and therefore tries to guess when DOS is done with printing - either by waiting a while or by using that PRN file close as trigger as somebody mentioned on the list. I think Windows will just send no data at all to the printer until either of the triggers happens. Earlier in this thread I included information on changing a wait-to-print item in Windows XP's registry. Something like that may be in Vista as well. Talking about your CPU time issue, did you try fdapm apmdos? It is meant to run on real hardware but MAYBE it is also of some use for Windows. Probably not, and in the worst case it just crashes, but I am curious :-). Whats the tamedos license? Here's TameDOS's web site http://www.tamedos.com/tame/tamehome.htm Here's the License page http://www.tamedos.com/docs/v50/license.htm In Bochs and dosemu, fdapm should work fine, but some configs of Bochs will produce lots of logging output when you use it so yet again it will be interesting to try :-) fdapm is a power control I thought. What role would it play for printing? LINUX with simulator and FreeDOS? It could be a consulting business. Dunno, dosemu works fine in my Linux, but I hear Clipper is one of the apps which sometimes need some fine tuning What I'm saying I've seen a old DOS programs that typically are for use in a specific industry or some specific regulatory.One was in the trucking industry to track insurance expirations for independent truckers. Another was for handling containers labeling paperwork which is handed to railroad transfer agents. Given today's Internet there may be a way to generate some business. Note: Clipper always needs tuning, particularly for the program of current disgust. I used the Blinker linker and it has a good DPMI. I turned off EMS and XMS and set memory to auto. DPMI is set to 8192 but a Blinker memory function reports that 45,000k is available. It has been a while since I looked at the link scripts. I got the Blink link script right by trial and mostly error having used a dozen third party libraries. If I were to change something it would take days to test and qualify it. Cheers -- John S.

Re: [Freedos-user] Some fix for Windows XP FreeDOS printing delays
Eric, Do you have any knowledge about the behavior of the PRN output. How would PRN behave in the situation that strings are output but no End-Of-Print-Job is sent? I just got the PCL5 programming technical reference from HP. As I remember from the earlier Laser Jets there is a timeout setting that ejects the current page. Maybe this will be sufficient for this problem. Printfil has a Windows print utility that intercepts LPT1 output from DOS programs. It routes that output to a file which Printfil watches. It then routes that output as Raw output or through GDI formatting. I found this utility a good idea but it was not printing reliably. The program itself did not crash when running. I wanted to mention TameDOS which tamed my Clipper application which was using 99% of the Windows XP CPU time. It worked ok and helped if running Windows programs along side DOS programs. The Clipper CPU time fell to 14% according to the DOS Monitoring utility. It would be a fine addition for a development or Game. I wonder how this would effect Booch's simulator with FreeDOS. I'm finding more of these obsolete programs that need to run in a modern environment. LINUX with simulator and FreeDOS? It could be a consulting business.

Re: [Freedos-user] Some fix for Windows XP FreeDOS printing delays
I was thinking it would be useful to have an escape key sequence of some kind. LINUX consoles have a [system-request] key feature that is a kernel option as I remember. Taking this thought further, a general facility defined in an ini-file that has escape-sequences matched to actions.

Re: [Freedos-user] Some fix for Windows XP FreeDOS printing delays
I was thinking the [SysRq] would be part of the kernel in the form of a key-action pair. The table would be loaded at boot time and would by-pass running programs checking keyed input directly. That is what the LINUX [SysRq] key sequence does. LINUX uses it for example to kill hung processes. It would also be possible to alter and manage the [SysRq] at the command prompt with some simple program. Routines to carry out requested actions are another issue. Something like simple sending end-of-print-job would be a BIOS like routine that hooks the printer output. Cheers. On Thu, Oct 9, 2008 at 12:40 PM, Alain M.

Alain, That's fascinating. I'll have to test that. As far as the DOS program I'm forced to use, updating it would require a large investment.

Re: [Freedos-user] [Xen-devel] Unable to boot FreeDOS 1.0
I don't believe the Xen environment has the capability to directly boot images from CD. I read an article in the Jan. or Feb 2008 issue of LINUX Pro from the UK, where they could not boot a CentOS install CD/DVD. They had a method of booting using a QEMU image as I recall from the hard drive. Next the QEMU PC emulation booted the CentOS CD/DVD. The article portrayed this a workable technique. Since I have yet to try that I can not say if this technique could be adapted to the FreeDOS iso image.

I guess your environment is a modern CPU with virtualisation extensions present and enabled? (as I don't think Syslinux, Memdisk nor FreeDOS kernel have built-in support for acting as XEN client). FreeDOS 1.0 ISO works like this: 1) Boot from CDROM in non-emulation mode 2) Load isolinux.bin (old version, version 3.62 is latest release) 3) Load isolinux.cfg configuration file 4) Press 1 to load FreeDOS (loads Memdisk, then loads /ISOLINUX/DATA/FDBOOT.IMG, which is a compressed 360KB bootable floppy image file ) 5) FDBOOT.IMG gets uncompressed in RAM, then is being executed (in RAM) by Memdisk in uncompressed form. 6) Bootsector is loaded, which in turn loads Kernel.sys (FreeDOS kernel) 7) Kernel.sys goes looking for \FDCONFIG.SYS and if that doesn't exist, \FDCONFIG.SYS. If that also fails, \COMMAND.COM 8) Selecting an option loads drivers and COMMAND.COM, then starts batchfile Knowing the layout of the 360KB diskette, I'd say the FreeDOS kernel is not able to find any files (don't see any menu option in your screenshot which points to no config.sys being found..nor can kernel find command.com). I don't know if XEN is to blame for this, or Syslinux, Memdisk or FreeDOS, or any combination of these issues. Could you refer me to the site which has a web-archive of the responses for the XEN mailinglists? Can't see if any threads with solutions were formed there. Alternative options are to remaster the ISO with 1.44MB floppy emulation enabled instead of non-emulation with Isolinux. Or ofcourse try a bootdisk first, instead of a bootable cdrom.

[Freedos-user] please do never send files to a mailing list
Eric, I noticed the remark in the Xen posting, please do never send files to a mailing list. I think that this implies the need for a hosted discussion group arrangement. That will preserve the history of discussions which I think has benefits for this group. Given a history it would be possible given a really good archive search, quicker answers to well know questions and associated replies. Threads can have comments added at any time, either immediately or even years later. If something happens to the maintainers such as an injury or worse other could be found to take their places. It would allow for a structured organization of question groups. It would not require each list member to maintain the archive of the questions and replies. It would also allow relevant files to be stored within the archive. Does sourceforge.net have this facility or would you have to go elsewhere to get these features? -- John S.

Re: [Freedos-user] trying to installa freedos on a VM
Jim, I've been putting a measure of time into the Xen environment. I've learned a few things, I'm an amateur as of now. The gist of what I know is that to run FreeDOS as a VM in Xen you need QEMU as a virtual hardware bubble. I believe Xen can run QEMU as a VM and FreeDOS inside that. I believe this because I read an article in LINUX PRO Magazine(as I remember) where CentOS's install CD would not boot directly with Xen. The article used QEMU's hardware emulation to boot the CentOS CD for installation. It worked then. The books below mentions the use of Boch's hardware emulation. You'll have to look into the details of Xen yourself at http://en.wikipedia.org/wiki/Xen. Note that Xensource is now owned by Citrix, the maker of Citrix Mainframes, a blader server like product. They are known to have a close relationship with Microsoft. Whether this is good or bad is not known to me. Try to Google 'Xen HVM' about the Xen Hardware Virtual Machine. Here are the books I've found at the local Borders and the Barnes and Noble. These two should give a fairly good introduction to Xen's Theory of Operations and how to setup and run virtual servers. ref: The Definitive Guide to the Xen Hypervisor; by David Chisnall; ISBN: 978-0-13-234971-0; 2008; Pub. Prentice Hall; $50; This book is a hardcore look at the architecture of the Xen Hypervisor with specific reference as to how it is implemented at the assembly language level of microprocessors. It works its way upward towards the details of the interactions of between master OS, dom0, and the guests, domU or Hardware Virtural Machines, HVM's. This is the foundation of how the Xen works. A pet peeve of mine is the lack of comprehensive Glossary, Chapter notes and references, and supporting Appendix. The index could have much more bulk to it as well, however this book is quite good. Xen is a moving target, many changes are being either discussed or implemented. One question that comes to mind is whether an online book would be a better at this point in time. Changes in Xen can be expected over the next few years. It would be good to have a ever changing reference. Professional Xen Virtualization; by William von Hagen; ISBN; 978-0-470-13811-3; Pub. Wrox, Wiley Publishing, Inc.; $50 This book is more about how to install, setup, and administer Xen based virtualization.

Re: [Freedos-user] Can't even get started!
Mr. Willard, The suggestions by the below long time FreeDOS users are a good start. It may be that you can figure this out on your own. That will make it easier for you to do more of you own computer setup over time. Learning new things is always good. That said this form may give you the guidance you need to reach your goal. There are many here ready to help as you have already seen. It is easier to learn to do things on your own if you have a working example. I can see it is a bit of a challenge for you now. There are experts here who have a great amount of knowledge. If you are completely stuck you may want to consider a paid telephone support session with one of the qualified experts. That is absolutely inline with the ideas of Open Source. Everything is not free with Open Source. Open Source is, well, open source. The source code is distributed and then if someone is pleased to do so, a binary, compiled, and ready to install CD or download is made available. A distribution is not a part of being Open Source, it is a community benefit. People who want are able to sell their services to support using an Open Source software package. Consulting, for example, is a time honored way for those who need it to get help. There are the FreeDOS developers who would greatly appreciate some compensation for their many dedicated hours. Just look up their names on the web site. They may or may not be interested in telephone consulting. As for myself, I've worked with most of the DOS derivatives for the last 26 years since MS-DOS 1.0. So I have a rough idea of how it works. I've been using FreeDOS for about two years inside LINUX and Windoze XP. Give me a try if others are not interested. Well I hope give some perspective to things for you. Good luck.

Re: [Freedos-user] looking for epson or escp printer users
I have used EPSON wide carriage and OKI 390 turbo letter width dot matix in EPSON ESC/P and ESC/P2 modeS with custom code I wrote. As long as the correct escape code sequences were sent to the printer the output whether character based or graphics worked. One thing is to be sure you have good documentation of how the escape sequences work. The web is a ready resource to locate that information. The old printed 20th Century documentation from the late 1980's and early 1990's was not of great quality just a listing of the sequences. Thing would go-bad when the communications path to the printer was not working correctly. An example was for a printer port driver was not sending characters with the 8th bit set. That really ate up some time to figure out. Check to be sure the escape codes are actually reaching the printer. How would you figure that out. 1.) divert the printer output to a file from LPTx: 2.) use a Hex editor or a programmer's text editor with a Hex mode such as you can get from http://www.vedit.com, a really high quality editor. 3.) examine the actual Hex code series that the file indicates the printer receives to see if the printer is getting proper escape sequences. OR Write short programs that output short escape sequences to test the printer behavior. On Feb 18, 2008 2:23 AM, Oleg O.

Only this year, somebody told me GRAPHICS would print an empty page for ESC/P, but he refused to help me to figure out why... GRAPHICS (the GRAPHPIN part of it) can do both 120x60 (on real 9pin: 120x72) dpi 8 pin modes (in /C mode) as well as 180x180 dpi 24 pin mode. I use the following sequences, ESC=char(27), CR=char(13), LF=char(10), FF=char(12), lo = /C mode, hi = normal mode: Init: Set line spacing lo: ESC A char(8) CR LF hi: ESC 3 char(24) CR LF Bitmap: Send one block of pixels lo, 31 columns 8 rows: ESC L char(31) char(0) hi, 70 columns 24 rows: ESC * char(39) char(70) char(0) Finish: Reset spacing, eject both: ESC 0 FF CR LF What namely does not work? ~2 years ago I tried GRAPHICS, but got bad results [on Epson LX300]... If you had told me, I could have repaired it 2 years ago... ;-) Eric PS: When I wrote GRAPHICS, I used DOSEMU to grab the printed data. I can send you examples of the PostScript output for testing on real printers, but it looked okay in ghostscript GV ;-). As for the ESC/P part, I tested by writing a minimal simulation of such a printer, with PNG output. So if that is broken, so is GRAPHICS. -- John S.

Re: [Freedos-user] File Access denied
The Clipper DB, a dBase language compiler, had locking mechanisms that were similar if not the same as the FoxPro as I recall. I had a book or a document that covered these issues but I can't take the time to look it up until this weekend. Sorry. Just remind me on Saturday morning to go look for the reference. Right now I can give you some links to projects that have dealt with these file locking and permissions issues. The Harbor Projecthttp://www.harbour-project.org/is an Open Source Clipper DB like or clone that has an MS-DOS version. I have programmed applications for MS-DOS using Clipper DB which did give me some trials and challenges when trying to prove the locking worked as expected. The Harbor Project http://www.harbour-project.org/ used the same API's with some helper code. The problem may be more of the way FoxPro interpreted the MS-DOS locking API. The other part of the issue as I recall was that the MS-DOS API required a fair amount of extra helper code to be usable. As I remember some Assembly is required. The Oasis Clipper source archive http://www.the-oasis.net/index.php3 may be a source of locking coding examples for Clipper. That may give you some ideas as to what the FoxPro issue may be. A Clipper news groupnews:comp.lang.clipperis also mentioned on that page where you may get information. I'm sure there is also a FoxPro version of that news group. Cross OS's file permission information is a long discussed issue on the Samba.org http://www.samba.org web site. Samba has a way to share drives MS-DOS system. The rub there, as you mention, is the LINUX permission system. Add to that the locking issues and things get interesting. Does anybody have a debugger or debugging solution for observing file locks or file permissions. This appears to me to be a problem with all OS's. It is much the same problem as I struggle with LINUX, Win OS's, and the MAC environments. I hate writing debugging code all the time.

For testing purposes, linux permissions are open on 777 recursively, but still the same problem. I have been struggling with this for 2 months allready. Even tried putting the shared files on a CIFS server. Same results. Does Foxbase allow to share file acces ? this would require an open in read-only, sharing access.

(please use plain text mail without html) Is there anybody that runs Foxbase+ V.2.0 for DOS on FreeDOS? What I am trying to achieve is run a foxbase application on Linux with DOSEMU and freedos. Right. Maybe you get better results if you load SHARE... Please also compare diskimage (can be diskette or special DOSEMU FAT16 as generated by dosemu tools) drives to Linux directory used as drive drives. Problems when several users access the same file sound like shared file access problems :-). Even though no one is editing the file. The users should still be able to view the database even if no one is editing the current dbf file. Eric - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Freedos-user] Dos help on FreeDos
A book that helped me learn the internal structure of MS-DOS is Undocumented DOS 2nd Ed. by Andrew Schulman, ISBN0-201-63287-X, $44.95 retail cost. There were several Undocumented books is a whole series. Examples were mostly in assembly code, my favorite high level language. It covers a number of more detailed subjects than most DOS books On 9/17/07, Jim Hall [EMAIL PROTECTED] wrote: Hi Allan! Been a while since I looked for a beginner book on DOS, but Special Edition Using MS-DOS(r) 6.22, Third Edition by Que looked pretty good. It even mentions FreeDOS! :-) Kind of a thick book. I lot of IT books seem to go for number of pages, unfortunately. I hope it doesn't scare you away.

Re: [Freedos-user] Partition layout
I've got a SUSE LINUX Pro 9.3, IBM PC DOS 6.x(drive C:), MS-Win98E(drive C:), IBM Warp 3(drive F:) on /dev/hda and booted using GRUB as a boot manager. GRUB has a number of features for booting most any OS which may help your situation. I hide and unhide various partitions as necessary to get the drive layout configuration. Notice that partition table entries are not sequential. IBM PC DOS 6.x boots as expected as drive C: while /dev/hda2 is hidden; the reverse is used when booting Win98 SE from /dev/hda2 instead of DOS. GRUB has many features one may allow your configuration to work. Here's the fdisk of it.

Booting FreeDOS 1.0, the W2K-D primary picks up the letter after any extended partitions. With DRDOS 7.01 Fat32, they hold their physical position. Extra (more than one) primary partition get a letter after all extended partitions. *That*is*the*rule*. If you boot Win98 or MS-DOS or FreeDOS from the second (physical order) primary partition, the other primary will also get the last letter. FWIK, if there is an extended partition between 2 primaries, it makes no differece. But I am only 90% sure of that. Some DR-DOS version have an extra bug, it has to boot from the first primary partition, that one will allways be called C: Alain - This SF.net email is sponsored by: Splunk Inc.
