I tried loading ANSI.SYS (from \os2\mdos) in the DOS Settings/Driver Settings and also in the boot CONFIG.SYS. I also tried the same with NANSI.SYS. The application still dies with an error that it can't find ANSI.SYS. This application runs fine under DOS 5.0. Will try a boot VDM next. Any other ideas? Thank you.. Eric J.

Under DOS 5.0 I used the SETVER to get the program to execute. I have changed the DOS_VERSION in the DOS Settings to include the program. But I still get INCORRECT DOS VERSION. This program is MSCDEX.EXE which is a TSR program for CDROM support. If I place this program name in the Program field then I cannot execute the next program. What do I need to do?

Mike, this was made by a company wivh is not followin its own rules. Solution: You need the V2.21 of MSDEX.exe , and you can download it from the M$ Multimedia BBS. By tomorow I maight can get their number. (Why dont you call MS?) the 2.21 works fine, with 2.0 and DOS5.(you don't have to trick it inDOS) Geza Szivos 403-290-6583 ----- OS2DOS CFORUM appended at 21:28:23 on 92/04/16 GMT (by LEOA at BCRVMPC1) Subject: Incorrect Dos Version Ref: Append at 21:58:19 on 92/04/13 GMT (by XXNOVA24 at TORVMCOP) MSCDEX 2.21 no longer looks for version - but I beleive you may still have problems running in an emulated DOS environment. You may want to create a DOS booted VDM. Has something to do with the fact that MSCDEX does not issue a clean int21 to check for version. Leo A ----- OS2DOS CFORUM appended at 01:58:31 on 92/04/23 GMT (by RAWILSON at STLVM20) Subject: How do you change the default settings for DOS sessions? If you use the OS/2 2.0 command START /DOS /FS progname to start a full-screen DOS program, DOS comes up emulating 2M of Expanded (EMS) memory, 2M of Extended (XMS) memory, and some amount of DOS Protected Mode Interface (DPMI) memory. Where are these defaults set? How can they be changed? I know one can use the DOS SETTINGS button to change the defaults for DOS sessions brought up via the Command Prompts folder, but how do you change the defaults for DOS sessions brought up via the START command? How do you make these sessions have no EMS, no XMS, and no DPMI memory? If each Virtual DOS Machine (VDM) starts with 2M EMS and 2M XMS memory which is never used, won't OS/2 spend more time paging than if each VDM starts with no EMS and no XMS memory? Robert A. Wilson IBM Santa Teresa Lab ----- OS2DOS CFORUM appended at 14:53:19 on 92/04/23 GMT (by XXNOVA24 at TORVMCOP) Subject: How do you change the default settings for DOS sessions? Ref: Append at 01:58:31 on 92/04/23 GMT (by RAWILSON at STLVM20) The defaults are determined by the config.sys. Example: DEVICE=C:\OS2\MDOS\VEMM.SYS 8192, 4096 gives you OVERALL SYSTEM LIMIT 8MB and DEFAULT LIMIT 4Mb to every NEW Dos Box. similar for the others too, like XMS the default is 1MB overall 4MB Geza Szivos (All this info from the OS/2 V2.0 Volume 2:DOS and Windows Red Book.

Error message says I need a minimum of DOS 3.0. Apparently OS/2 1.3 DOS BOX is earlier than DOS 3.0. Any suggestions? Fixes? Kenneth J. Kellow ----- OS2DOS CFORUM appended at 22:05:52 on 92/04/23 GMT (by IVERSON at FSHVMX) Subject: LOTUS 123 v3.1 and OS/2 1.3 Ref: Append at 18:33:01 on 92/04/23 GMT (by KKELLOW at BTVLABVM) I don't have personal experience with this, but several appends in LOTUS123 FORUM indicate that 3.1 will not run under OS/2 1.3, but will run under OS/2 2.0. Perhaps asking this question in LOTUS123 FORUM might yield a wider audience of 123 experts. Also, consider moving to OS/2 2.0; "catch the wave!"

The DOS box in 1.3 has no access to extended or expanded memory. OS/2 2.0 provides each DOS session with as much extended or expanded memory as you want.

I have successfully loaded Lantastic workstation and am able to access both the servers on the net while in the virtual DOS machine. What is required to give OS/2 access to these redirected network drives? FSACCESS just trashes the drive table when executed. I'm guessing that netbios support will be required.

It runs fine in DOS 5.0 or in a booted DVM which boots DOS 5.0. However in a OS/2 dos window or full screen, it appears to be unable to find some files. I have incresed the FILES setting, to no avail. The vendor is over due on the next release and does not appear to have any interest in talking about the current release and OS/2. Are there any tools or traces that might show what if any of the many DOS setting might fix this problem. I guess I should be happy for Booted DVM's but it seems like a pain to gothrough each time. ----- OS2DOS CFORUM appended at 22:57:12 on 92/05/04 GMT (by RAWILSON at STLVM20) Subject: Booted DOS vs Dos Settings Ref: Append at 19:30:26 on 92/05/04 GMT (by TSO09 at OS2CUST) Compare the AUTOEXEC.BAT file you use with DOS 5.0 to the one OS/2 runs when you bring up a DOS VDM (usually C:\AUTOEXEC.BAT). I suspect there is an environment variable being set in the DOS 5.0 version of AUTOEXEC.BAT that it not set by the OS/2 VDM version. It should look something like this: set clarpath=c:\clarion This tells the Clarion application where to find the files. (This is just a guess -- I am not familiar with the Clarion product.) Robert A.

A DOS extender is a mechanism that allows a program to run in protected mode and reap its many benefits (the main one being a large unsegmented address space). The problem is that OS/2 itself runs in protected mode and provides support for DOS applications through virtual DOS machines (VDMs). OS/2 2.0 VDMs are allowed to enter and use protected mode so long as they use extender technology that OS/2 supports. To the best of my knowledge (often limited and seldomly complete) the only extenders and extender related technologies that 2.0 supports are DPMI, EMS, and, XMS. Apparently AutoCad does not use a DPMI compliantextender. Chris C. American Management Systems ----- OS2DOS CFORUM appended at 05:07:38 on 92/05/06 GMT (by SBCY006 at OS2CUST) Subject: Lan Support does not work with Netware Requeter I put this in the Netware forum already but I wasn't sure if it should go here also. It really depended on your opinion. I was trying to run the Netware Requester and the DOS Lan SUpport together with only one token-ring adapter. It doesn't work because the OS/2 Netware Requester gets basicly an exclusive enqueue on the adapter then when a DOS box comes up it can't get it. You could say Novell should have included a virutal 802.5 driver like they included virtual ipx driver. Or you could say that the Lan Support people should have created a OS/2 NDIS driver for with ODI drivers like Comm. mgr. or Netware Requester. IBM is looking into it. ----- OS2DOS CFORUM appended at 13:34:48 on 92/05/06 GMT (by IL69112 at OS2CUST) Subject: Microsoft Mail ver 2.1e I am running Microsoft Mail ver 2.1e External Mail program in a dos window. The program can utilize netbios for instant mail notification on incoming mail fro m remote dial or postoffices. When I start the program, the software initialize s and then gives the following message: "Insufficient network resources (comman ds) netbios started?" It will then procede after pressing a key, but the progra m will not use instant notification. My question is this; how can I get the pro gram to netbios in the dos window so that it will work correctly? ----- OS2DOS CFORUM appended at 14:17:51 on 92/05/07 GMT (by XXCITY06 at TORVMCOP) Subject: Excelerator 1.94 from Intersolv on ISA clones Excelerator 1.94 from Intersolv is a CASE tool that runs on full______ screen DOS.

The interaction and compute time is great but when attempting to print it takes forever compared to standard DOS 5.0. Any thoughts on this?? ----- OS2DOS CFORUM appended at 15:29:23 on 92/05/08 GMT (by HITTR at OS2CUST) Subject: Expanded Memory We have not been able to get expanded memory in the DOS Full Screen or DOS Wind ow on some machines. The machines (an IBM Model 95 and Memorex Telex 8257) run fine expect for the ems memory. My SE and I called this in with problem 6x931 , but help seems to be swamped. The 95 is one of the first 95s. Expanded memo ry seems to be NO problem with IBM Model 55s, Model 70s or the Memorex Telex 72 55. Is there a hardware problem? ----- OS2DOS CFORUM appended at 18:47:20 on 92/05/08 GMT (by HALLERMA at BCRVMPC1) Subject: Expanded Memory Ref: Append at 15:29:23 on 92/05/08 GMT (by HITTR at OS2CUST) To have EMS, you need a 64kb "page" free in the C000 or D000 area just below 1MB. Run your Reference diskette and check the configuration. Maybe some adapters can be moved around to free up the 64kb "hole". Mel Hallerman ----- OS2DOS CFORUM appended at 19:43:45 on 92/05/08 GMT (by IL14094 at OS2CUST) Subject: IBM LANACS and Attachmate 3270 Gateway Does anyone know if IBM's LANACS program will operate in an OS/2 v2.0 VDM? I have the same question about Attachmate's 3270 gateway. These apps don't put much of a load on a server so I'd like to start combining some of my machines so that I can get away with fewer servers and provide backup machines. Obviously the best solution is for these to be true OS/2 apps, but I'll probably never live to see the day when that happens. ----- OS2DOS CFORUM appended at 03:14:38 on 92/05/10 GMT (by XXUWAT06 at TORVMCOP) Subject: Autocad version 11 Ref: Append at 16:21:59 on 92/05/05 GMT (by AAAK2J5 at OS2CUST) You probably won't like this answer, but I've been running ACAD for OS2 since 1.x - the same ACAD package - and it works just great under 2.0, as it did with all the beta version. As you may know, ACAD for OS2 is version 10. It has many of the features 11 seems to have from descriptions I read. It also seems to have features that have been built into ACAD for Windows! Why don't you write to Autodesk and ask them when they plan to upgrade their OS2 version? Elliott M. Avedon University of Waterloo (519) 885-1211 x2204 ----- OS2DOS CFORUM appended at 17:59:02 on 92/05/11 GMT (by IL22868 at OS2CUST) Subject: Expanded Memory Ref: Append at 15:29:23 on 92/05/08 GMT (by HITTR at OS2CUST) Even if you don't have a 64k "hole" available, you still might be able to implement expanded memory. The following is from a draft extract from ITSC Red Book OS/2 Version 2 GG24-3731: "There is really no solution to this problem (sometimes known as "RAM Cram") under DOS. However OS/2 V2 provides an elegant alternative. ..."But since the VDM occupies VIRTUAL memory this can easily be changed. The DOS Settings value 'Other: Include Regions' parameter releases adapter addresses for use as EMS or UMBs. In most cases this can be set to the complete X'C0000'-X'DFFFF' range. "If a VDM uses an adapter DIRECTLY (usually via DOS device drivers), any adapter ROM or RAM address must not be specified in Include Regions. Addresses of adapters used indirectly by the VDM (through OS/2 V2) may be included. For example, the full X'C0000' to X'DFFFF' range may be included on a SCSI-based PS/2, even though the SCSI adapter ROM may occupy X'D8000' to X'DFFFF'. The DOS VDM does not directly access the SCSI adapter so doesn't need SCSI ROM mapped into its address space. It can still access files on SCSI disks via the OS/2 V2 Filesystem." ----- OS2DOS CFORUM appended at 18:54:13 on 92/05/11 GMT (by IL19543 at OS2CUST) Subject: IBM LANACS and Attachmate 3270 Gateway Ref: Append at 19:43:45 on 92/05/08 GMT (by IL14094 at OS2CUST) My SE had sent me this about LANACS Server under OS/2, so it sounds like IBM is working on LANACS. To: LAN Async Requirements Responders SUBJECT: LANACS on OS/2 For those of you that required LANACS like function on an OS/2 base, we have a start. We have installed a system with MOST, OS/2 V1.3 and OS/2 V2.0 in our lab. We are able to run LANACS in the OS/2 V2.0 full screen DOS window and let it run in background mode while we continue to do OS/2 processing. We are also able to run LANACS in a DOS PM Window and leave it visible on the screen while other work is being done. We tested with only one com port so far. But we do intend to install an RTIC card and test with modem pooling and port contention. It is interesting that want you want to do with your OS/2 Servers is exactly what we want to do, run several of these communications processes on one box. Hopefully OS/2 2.0 will allow us to do this with stability. Regarding the Extra! Gateway, do you know whether this uses just NETBIOS, or do es it use the 802.2 level also. I do know that the gateway uses NETBIOS from the gateway to the workstation, but not sure about gateway to host (assuming a token ring connection upstream and downstream of the gateway.) There is the Virtual Netbios which the Extra! software should be able to use, but no Virtual 802.2 support is there yet. Extened Services also has a SNA Gateway built into it. You could look at that option also (if you are not already aware of this). Mike Long Iowa State University ----- OS2DOS CFORUM appended at 19:32:17 on 92/05/11 GMT (by TKING at BTVMANVM) Subject: DOS Program Performance under OS/2 2.0 I understand (somewhat) about the DOS Settings in a VDM. My questions are different: -- What can I do when writing/modifying a DOS program to make it "OS/2 2.0 Aware" that will improve performance? -- How can a DOS program more effectively 'yield' to the System when it is idle?? Examples: waiting for Keyboard input, or doing an intentional delay, or doing I/O. -- What is an effective way of doing a delay within a DOS program that won't eat OS/2 2.0 cycles? -- Can some of the 'tricks', such as calling INT28H, used in 'multitasking' DOS help in this arena? -- If I write Two DOS programs that I know will often run together under OS/2, how can I optimize their sharing of the system resources? -- ISTHERE anyway to set different priorities / percentage of cycles available betwen two DOS programs? -- What are good inter-program communications choices between DOS programs under 2.0? An OS/2 program and a DOS program?? So, that's the general subject.. Any pointers, ideas, references etc would be apprciated. If there's any better (or concurrent) Forum discussing this area please advise...

I contacted my SE to get OS/2 LAN server V 2.0 network administrator supplement for OS/2 2.0 S04G-1080 but she said that it is not available yet. Could anyone tell me when these books will be availab le (we were in the ESP but did not see this book), or could you give me a quick rundown on the syntax. ----- OS2DOS CFORUM appended at 16:35:13 on 92/05/12 GMT (by IL22868 at OS2CUST) Subject: LTSVCFG utility Ref: Append at 13:48:17 on 92/05/12 GMT (by ISU102 at OS2CUST) There are two key points to running DLR in a DOS VDM: (1) You must start a specific version of DOS in the VDM (e.g., boot a DOS 5.0 diskette/image); and (2) You must run LTSVCFG before any NETBIOS applications (including DLR) are started. Foloowing is the syntax for the LTSVCFG command: d:\IBMCOM\LTSVCFG S=s C=c N=n where: d is the OS/2 boot drive, s is the number of NETBIOS sessions, c is the number of commands, and n is the number of NETBIOS names. ----- OS2DOS CFORUM appended at 16:35:26 on 92/05/12 GMT (by HAMMOND at RCHVMV) .....

Use '/' to separate parameters for a second adapter. You must 'over configure' Netbios resources to account for resources obtained for DOS MVDM. I had the same problem getting documentation. Also, if I start DOS MVDM using Netbios support before starting OS/2 Lan Requester, this works. However, other order fails. Does anybody have any information on why Netbios support in DOS MVDM is dependent on start order with OS/2 Lan Requester? ----- OS2DOS CFORUM appended at 04:57:32 on 92/05/13 GMT (by GULLEY at BCRVMPC2) Subject: DOS Program Performance under OS/2 2.0 Ref: Append at 19:32:17 on 92/05/11 GMT (by TKING at BTVMANVM) Making a DOS application aware of OS/2 can be difficult if it is to run on DOS systems also. Part of the object of VDM's, like VM86 mode under EMS memory managers, is that the application does not know it is being controlled by OS/2. The best way for DOS programs to yield to OS/2 is to use the standard DOS INT's for all I/O where possible. While slow death under DOS, it can be a big performance advantage under OS/2. A DOS based application spends it's idle time looking for something to do. They check for keyboard and mouse input. They also tend to use the BIOS INT 16h calls directly, using function 11h to check for status first and then doing mouse device driver call, etc. An editor I use just does the direct INT 16h, function 10h calls. It wastes no cycles with OS/2. Your problem here is that the DOS single thread model and its device driver interface assumes it owns all the processor cycles. This is why the shift to the PM and Windows model is necessary. For delays (longer than 1 millisecond) you could try using the BIOS INT 15h, function 86h, WAIT function. This should be yielding to OS/2. I have not tried it, but it would be one way for a DOS based application to yield to others, as there is no way to assign processor usage between different programs.

They want to move their existing DOS apps over to an MVDM and run them as much as possible as is. One of their Netbios apps needs to be non-swappable (I just heard this from the account team so I don't know the reason why yet). I don't know of any parameters for a DOS session that would do this but there's definitely a lot I don't know. Does anyone know of a way to do this? The main issue here is that they only want this one app to be fixed. All other apps should be swappable. The customer currently has over a thousand PS/2's running these apps so the opportunity is there if we can get them over a few of these hurdles. Thanks in advance.

Therefore, if they are "hooking" an interrupt, and that interrupt is triggered often enough, then the DOS application will stay resident (becuase it is "active"). Note that the DOS Setting of DOS_BACKGROUND_EXECUTION should be set to ON -- (the default). It seems that alot of people are suffering from OS shock/ mis-trust. By this I mean that they are used to running under DOS, and since DOS was never stable in a multi-tasking environment, even with deskview, and/ or Windoz, they think that "they" must tell the OS what to do. OS/2 doesn't seem to be baby-sat like Windoz for example. Just set up the application, and let OS/2 take care of the rest. pgk ----- OS2DOS CFORUM appended at 01:58:44 on 92/05/14 GMT (by IL19543 at OS2CUST) Subject: Making a DOS app non-swappable Ref: Append at 12:57:30 on 92/05/13 GMT (by JCURRAN at DETVMIC6) Jim, In 1.3 we had the NOSWAPDOS parameter in config.sys MEMMAN line.

They are trying to run 3 DOS programs on an OS/2 V2 machine at the same time. One is a Netbios program with their own Netbios drivers, one is a badge reader program communicating with an artic card, the other is an async program. They have tried these on a 4MB and an 8MB machine (mod 57). The Netbios app is polled by three or four cash registers in order for files to be transferred to the OS/2 machine. If the Netbios app does not respond to the request for transfer within 5 seconds, the registers fail with a time out. With all three of these programs running, the registers have consistenly timed out. If they only run the Netbios app, it functions but seems to be about twice as slow as the native DOS machine, on both the 4MB and 8MB machines. With all this said, the issue then is why is the VDM performing so slowly and can we improve it. They have tried changing some of the DOS settings but nothing seemed to help. Any suggestions?

I get a SYS3176 which means that a program I tried to execute had a problem. All that is executed is the autoexec. When I execute a DOS program from an OS/2 window, a DOS window gets created and the autoexec is executed without a problem. If I shutdown and re-boot, the problem goes away and I can bring up the DOS box. The only thing I can think of that I may have done to cause the problem is to close the DOS box which was running an application at the time. This shouldn't be a problem if it is indeed the cause because OS/2 tells me that an application may be running and asks if I really want to close.

Fewer interrupts will now be generated, with multiple characters transferred per interrupt... and since the interrupt overhead was _far_ greater than that for the actual data transfer you can now run the port at higher speeds without losing data.

OS/2 can reach around 1,100 per second, and that is the entire systems capability, disk writes, screen updates, timer handlers, etc. Speeds above 9,600 baud really tax it, and traditional fullscreen terminal/ communications programs that write to the screen and disk as well as communicate, can't exceed this speed, while ones that only present status while communicating can go faster.

I tried asking this question in the 'General Q&A' forum, and have received no answer. Let's try this forum: When features for OS/2 2.0 were explained to us last year, we were told that both DOS MVDM and OS/2 sessions would have math co-processor emulation supplied by OS/2 2.0 base allowing all applications to use floating point instructions, whether or not a machine in fact has a co-processor. We know we don't have DOS support, and don't believe OS/2 support exists either. In fact, we've heard nothing at all about it for several months. Was this feature dropped? Will it be supplied in a CSD? ----- OS2DOS CFORUM appended at 15:42:09 on 92/05/21 GMT (by SAMI3QU at OS2CUST) Subject: Serial communication speed in a VDM Ref: Append at 19:37:56 on 92/05/20 GMT (by IRV at BCRVMPC1) - I realize that CPS is not necessarily equivalent to interupts per second. However, in my original post I stated that my port is equipped with a 16450- compatible UART, which does not have the 16-byte FIFO buffer. In order to upload data at 1140 CPS (sustained), 1140 interupts per second must be generated in addition to any other interupts. In order to download at 1100 CPS, OS/2 must handle 1100 interupts per second from the serial port as well as console, disk I/O, etc. I'm not complaining as this seems to be working fine for the most part. I'm just curious because the fact that it's working seems to contradict statements concerning OS/2's ability to generate and handle interupts (at least in a VDM). Mark Thompson Coal Services Corp.

Depending on the program though, there is no such thing as a standard interrupt from the modem to the port, and since virtualized to the S/W. Some modems will do some level of packing, like the 14,400's that really work at 9,600. All I can say is that depending on the program and system activity, 9,600 may be on the edge of what OS/2 can handle. We are looking at ways to expand this limitation. Here are some notes I have on the VCOM design.... VCOM.SYS supports DOS Applications which do RS-232 communications in a virtual DOS Machine of OS/2 2.0. VCOM's basic function is to support INs, OUTs and INT 14h for the RS-232 ports while acting as a traffic cop (keeping multiple applications from walking on each other while using the RS-232 hardware). To do this, VCOM traps all access to the COM ports and routes the access to the underlying physical device driver (COM.SYS) for actual execution of the function. VCOM provides a standard interface to all DOS applications (it looks like an 8250) while the underlying COM driver is free to take as much advantage of the real hardware as possible. The 8250 was chosen since it is the lowest common denominator (more apps support it than any other chip) and because the state machine required to emulate this chip is smaller than the other, higher function, chips (16550A). Although you have a different chip, we respond to the program as an 8250 and then use your H/W and it's resulting boost.

If so, we have seen problems with EMS memory in MVDM. You can check for this problem by starting a MVDM session, and entering the MEM command. If the command does not report any EMS memory, you probably have the problem I've seen. Be sure to use a MVDM session that has a non-zero setting for EMS memory in the 'Settings' dialog (use OS/2's DOS). To correct this problem, boot a setup diskette and shove the ROM/RAM for the Token Ring card to either the highest or lowest available settings. After re-booting OS/2, the test with MEM command should report EMS memory. Apparently, the OS/2 MVDM EMS support requires a 64K block in high memory to function. Token Ring card ROM/RAM were placed in the largest hole in high memory, complicating life for EMS users. By the way, if you have this problem, **none** of your MVDM sessions will have EMS memory.

Ref: Append at 14:08:18 on 92/05/21 GMT (by AOI1075 at OS2CUST) The support for the math coprocessor is there. However, if the program you are trying to run checks to see if there is a coprocessor and there is not, OS/2 will tell the truth. So, if your program doesn't check for a coprocessor, it can use it just fine. Douglas D. Flint ----- OS2DOS CFORUM appended at 19:48:35 on 92/05/22 GMT (by IL78568 at OS2CUST) Subject: What happened to 80x87 emulation? Ref: Append at 19:43:57 on 92/05/22 GMT (by DFLINT at RALVMA) I would think that most well-written programs requiring the use of a math coprocessor, WOULD check for its presence before continuing. Thus the ability to emulate the processor would have limited usefulness. Perhaps a Settings entry, or a CONFIG.SYS entry could be added to lie about the presence of the coprocessor.

It seems that the idle sensitivity does not work with all programs. It seems to work with some programs (Brief editor, List by Beurg) which use the INT 16 call to check for a key stroke, but other programs which call exactly the same INT calls use up 100% of the cpu cycles. DataEase for DOS yields time slices properly under DesqView, but uses 100% of the cpu cycles under OS/2. Programs I have written that call the same INT 16 functions that Brief calls, in the same order, use up 100% of the cycles. This is totally independent of whatever I have set for idle sensitivity.

For instance FAX programs that run at 9,600 baud. This is approximately 960 interrupts to start with. The real cruncher is what these program try to do with the disk and display, and what is running in the rest of the machine. Bear in mind, higher speed COMM speeds (19,200 baud will work) and if you remove the loading of BOTH COM.SYS and VCOM.SYS, you can manage the use of the COMM Ports and not worry about that portion. Programs that suffer the most from this limitation, almost to a specific set are GAMES that use the timer to speed up the system and get more interrupts to produce sound (like REALSOUND). That is why these programs tend to either hang the system or just about lock it up or severely slow it down. Some will work properly if REALSOUND is NOT used while others just will not work. We are looking at solving this problem at this time, but we do not have an easy fix handy.

If that fails to work, you could get rid of the above setup, rem out the com.sy s and vcom.sys lines in config.sys, reboot, and then have your DOS application setup to output to the COM port, with baud rate, etc. This may not allow OS/2 and other DOS apps to use the COM ports, but may help you in your debugging your problem temporaily.

You should be able to just type the above statement in the window that DOS_DEVICE has for such settings. I know that you can load the LanSupport drivers in this DOS_DEVICE box with exactly the same syntax that you do in your DOS config.sys.

And the setting does seem to be retained before the shutdown. This is a peculiar problem, as I have seen it happen repeatedly on two different machines at a customer location and have never been able to recreate it on my machine in the office. The customer systems have 3 different DOS apps running in VDMs, all of which have MANY of the DOS settings customized. The testing I've been doing at the customer site has involved extensive tuning of the DOS settings. It may be that this problem is related to simultaneously changing many of the DOS parameters?.. I've also found that although IDLE SENSITIVITY can be changed on the fly, the changes don't seem to make any difference. It only seems to have an impact if the change is made to the regular settings, save, shutdown, reboot. (In spite of this minor hiccup, we tested these same 3 DOS applications running on OS/2 V2.0 and Windows 3.1 (on the exact same hardware configuration, which by the way had only 4MB of memory) and the OS/2 system consistently outperformed the Windows system.

That is, associate a particular DOS environment with a program rather than associating a particular program with a DOS environment (I know that's an obscure play on words).

It appears that 4,259,840 is the maximum number of bytes of EMS memory that I can get in a DOS session, regardless of the setting of EMS_MEMORY_LIMIT. I am running on a PS/2 70-121 with 6MB of real memory. Setting EMS_MEMORY_LIMIT smaller than this, of course, causes less EMS memory to be allocated. This leads me to the following question... Is virtual EMS memory allocated from virtual (i.e. paged) memory, or is actual physical pages reserved for the VDM from available real memory (with other stuff presumably being paged out to make room)? 4 MB is about what I would expect if it's the latter. On the other hand, the description of page management in the OS/2 2.0 "Red Book" (GG24-3730) does not mention anything like this (I would assume that EMS pages should just come from process virtual memory).

As far as your problem goes, I've found that the state of the com ports after boot is somewhat unpredictable. The ports did not always take on the documented defaults. I put a RUN=C:\OS2\MODE.COM statement in my config to set the port automatically. The type of modem your client is using has some effect on how you want to set up the port, but here are a couple of commands you can try. For 2400 bps modem using XON/XOFF flow control: RUN=C:\OS2\MODE.COM COMx,IDSR=ON,ODSR=OFF,XON=ON,DTR=ON For a high-speed modem using RTS/CTS flow control: RUN=C:\OS2\MODE.COM COMx,IDSR=ON,ODSR=OFF,OCTS=ON,RTS=HS,DTR=ON If your client's serial port is equipped with a 16550 UART, you also want to add a BUFFER=AUTO parameter. Make sure that both the modem and the comm. software are configured for the same type of flow control.

So long as I start the DOS session using Netbios before starting OS/2 Lan Requester, everything works. Other order fails. I have checked the Lan resource values to make sure Lan Requester does not take all (or almost all) the Lan resources; the DOS session should work when started second, but it does not. Have you tried starting things in a different order(s)?

If so, what do I need to do to stop the reboot I'm getting at present? I've "hooked" the ALT-ESC using DOS settings, but I don't see a way to do the same thing for C-A-D. 2)My app is a communication TSR that seems ill behaved. Sometimes it works, most times the "line drops" and my session is hung. I've tried playing with as many settings as seemed reasonable, but I still can't make the app run as if I was in a DOS machine. I hook the keyboard, timer, and utilize hardware vector table INT 5. My question, does this app sound like one of those hardware intensive, timing critical apps that may never run?

What I don't know is whether the time critical setting will filter down into a dos box, the docs for the program say "It periodically re-sets the priority of all subprocess of" the started OS/2 session? It came with source as I remember, maybe you could modify it to suit your needs.

To enable EMS memory, you must have 64K of address space available above the 640K line. With multiple adapters in your system you may not be able to obtain this 64K. By using your reference diskette you can identify memory addresses available. If you have enough memory available to address, you can use the MEM_INCLUDE_REGIONS to define 64K of memory to address. If your system does not have 64K of memory address available you may still be able to define 64K by including the memory address space of an adapter that will not be used in your DOS application. For example: if your machine has a Token Ring adapter but your DOS application will not require access to the Token Ring, you can include the memory area defined for the Token Ring Adapter. Likewise, the address defined for the IBM SCSI adapter can be included for your MVDM session since disk I/O is provided by OS/2, not the MVDM. For more information check the system HELP for MEM_INCLUDE_REGIONS.

Your response leads me to another interesting question though. I am currently running Crosstalk from the network server, so in order to get the application to appear in the LAN users' Public Applications folder, I am fooling LAN Server into thinking it is an OS/2 application and invoking a .CMD file, which in turn points to the .BAT file that starts the application. In this scenario, have you found a way to customize the VDM DOS Settings (such as IDLE_SENSITIVITY, etc.)? I have not, however, it would be very useful for many of my LAN applications. Also, since my first question, I have witnessed two more strange aspects of this Crosstalk situation. First, every once in a while, the screens fill normally - no small chunks, of data, no screen corruption. I haven't found a pattern to this yet. Second, you know how Crosstalk counts the seconds when trying to connect to the LANACS server and when it is dialing the number called? Every now and then, it counts the seconds at a BLAZING speed. If I abort out and re-start the application, then it counts normally again. If you or anyone else have ever seen anything like this, or have any suggestions how to start tracking this down, I would appreciate hearing from you. Thanks much!

The type of memory management is important, whether it is DPMI, XMS, or EMS. You can also alter the settings to place DOS high, to give as much of the base memory as possible to the application. We have a problem if VCPI is required, as OS/2 does not support that memory management specification for DOS.

The program that surfaced this problem is RN for PC WEEK or PC MAGAZINE. It does some directory/file maintainence for you, one of which is to allow you to change the TIME STAMP on files. How it does it is to OPEN the file for READ ONLY access and then change the date and time and CLOSE the file. Very safe and the date and time is changed under DOS with no possible way of altering the data. Well, under OS/2, openning a file READ ONLY is just that, the entire file and it's attributes are READ ONLY, hence the program fails. I went in circles with this, but it boiled down to HPFS doesn't work this way, too risky to change both, and it really is a BUG in DOS. That is the bad news and the history. I had been told a fix was 'slimed' into OS/2 2.0 just for this type of problem. I DO NOT KNOW for sure what was, but I think it is FFIX.EXE. It is a DOS TSR that you run before a program, then FFIX /u to unload it. Give it a try and see if it works, I don't have anything to test it on or I would.

I didn't try anything ambitious like you, but used the following work-around when booting DOS 3.30 from an IMG file on the C: drive: On the diskette (thus in DOS330.IMG), the AUTOEXEC.BAT file looks like: @ECHO OFF SET PATH=C:\U\DOS3.30; SET COMSPEC=C:\U\DOS3.30\COMMAND.COM C:\U\DOS3.30\AUTOEXEC.BAT This allows me to move the real contents of AUTOEXEC.BAT out of the IMG file, so I can access it directly in 2.0. The file C:\U\DOS3.30\AUTOEXEC.BAT looks like: @ECHO OFF SET PATH=C:\U\DOS3.30;... etc. ... etc. ... CD \U\DOS3.30 C:\OS2\MDOS\FSACCESS A: The IMG file contains only the minimum files to boot DOS, and I point the shell to the C: drive. When FSACCESS runs as the last thing in the fake AUTOEXEC.BAT file, nothing is required from the IMG file. This wastes some space, but has the advantage that I only need to re-build the IMG file for changes to CONFIG.SYS. You can make a 720K image instead of a 1.4M image. This boots DOS 3.30 cleanly to a command prompt in about 4 seconds.

Frankly, I believe that this is taking "virtual DOS" just a bit too far. Multitaskers like DesqView and even Windows have some way for a DOS program to indicate that it has no work to do, and that somebody else should be run for a while. In my opinion, OS/2 should too! It just doesn't make sense to me to fail to provide some way for a DOS program (which certainly can figure out that it's running in a VDM) to avoid having to "spin its wheels" for a full time slice when it could release its time to some useful work. I believe that, if such a "hook" was provided, a lot of applications would make use of it. This is something that can be done far more cheaply than rewriting an existing application to run in OS/2 native mode -- and it could have a significant impact on system performance. The "IDLE" settings just don't give you the same level of control that a real interface would.

If the DOS program is polling (spinning its wheels), then it is not idle and would not use the hook if it were available. OS/2 programs work much the same way (no explicit call to give up the remainder of a time slice). This is my understanding of how things work, and could contain errors.

Thanks for the suggestion, though. / Bob Bob Beilstein, Manugistics, Inc. ----- OS2DOS CFORUM appended at 03:49:16 on 92/06/25 GMT (by IL48722 at OS2CUST) Subject: OS/2 Internals (was: Releasing VDM time slice) Ref: Append at 14:23:57 on 92/06/24 GMT (by FIECHTNE at BCRVMPC1) It was clear that there had to be SOME sort of "back door" communications path between the DOS and OS/2 kernels. While I know that IBM really wants people to develop for the 32-bit world, the realities we face are a huge installed base of DOS systems, and a much smaller set of 32-bit OS/2 ones. The chances of my rewriting my application as a 32-bit OS/2-only one anytime soon are not terribly great. On the other hand, if I have a way to "talk" to the OS/2 kernel from my DOS program, I can fairly easily build in OS/2-specific features, while still keeping a single product which will also work on DOS workstations. This, I believe, has the possibility of driving OS/2 sales (to get to the features unavailable on "bare" DOS), while not requiring me to abandon my DOS users (or stretch myself so thin trying to develop and maintain multiple versions of my code that I can't keep up the quality). This, however, requires that IBM enhance (and DOCUMENT) this "back door" path into the underlying OS/2 environment, as well as provide a way to unambiguously tell whether you're running in a virtual machine or not (even in Virtual Boot mode). I can't afford to rewrite my application, but I can sure build in some attractive OS/2-specific features if you only give me the tools to do so!

However, at this point, enhancing DOS' function is not in my charter. I am tasked with improving what we have in the field so it runs all the current DOS applications. I will add this to the "wish list" for the future but that is all I can do right now.

Getting this put on a "wish list" is fine. Frankly, I'd MUCH rather see you folk concentrate on giving me some way to support high-speed (i.e. >19,200 bps) communications programs in a VDM. The new COM.SYS and VCOM.SYS drivers go a long way toward solving the functionality problems (with HW_COM), since this will actually let me control DTR and the FIFO's, but using HW_COM actually degrades throughput -- presumably because the actual number of interrupts being passed to the VDM (as well as the timing requirements) is increased. If you can give me some way to mark one of my VDM's as "real time" (i.e. to be given special handling), or some other way to handle more than the advertised 1,000 interrupts per second, I'll be really happy! HW_COM is just soooooo close to what's needed... Anyway, thanks again.

Ref: Append at 14:18:45 on 92/06/25 GMT (by SSIA013 at OS2CUST) This property makes a Virtual DOS Machine(VDM) act as if VCOM.SYS was not loaded in the system (REMed out in the config.sys). This was intended for those programs which have either extremely sensitive timing for polling hardware lines or use the RS-232 in a "non-standard" way. LapLink versions before 3.0 are an example. The COM hardware is still accessible by the application but the OS does no manipulation of the hardware for the application so you will loose data at higher BPS rates. Especially without a buffered UART (NS 16550A or higher). Mark Fiechtner ----- OS2DOS CFORUM appended at 12:57:28 on 92/06/26 GMT (by SAMI3QU at OS2CUST) Subject: HW_COM -- What's this?

The term program seems to have problems reading from the serial port. Only a small amount of data makes it from the serial port to the term program and then the term program hangs. I've tried this on two different systems, one using Crosstalk Mk4 V2.1 with a 16450-compatible UART and the other using Telix V3.12 with a 16550 UART (both are 386/33 machines). A friend runs a WWIV bulletin board under OS/2 2.0 and experienced the same problem (386/33, 16550). Is there something else that we need to do to make this work properly? Thanks for any info.

There are some conditions; OS/2 2.0 must be loaded on an extended partition. It is a bit tricky because you have to set up a special CONFIG.SYS and AUTOEXEC.BAT file to do this (which I have done) and you have to change the DOS SETTING parameter DOS_STARTUP_DRIVE (to point to drive C). My question: The OS/2 docs refer to loading DOS 5.0 on drive C:, does this have to be the root of drive C, or can it be in a subdirectory? My DOS 5.0 is loaded in C:\DOS, and I created my special CONFIG.SYS and AUTOEXEC.BAT files in directory C:\DOS50VDM. When I set the DOS_STARTUP_DRIVE to point to C:\DOS50VDM, OS/2 presents a message that it can't open a device or file. If I set the DOS_STARTUP_DRIVE to just C:, DOS 5.0 boots using my original CONFIG.SYS and AUTOEXEC.BAT files. It does boot up, but generates errors from various DOS specific drivers. Any help???

I did some experimenting by using a utility that I own. I made the IBMDOS.COM and IBMBIO.COM files unhidden, then copied them into the C:\DOS50VDM\ directory that I setup. This still didn't work, because as you pointed out, I need to have a second boot sector on my C: drive which would point to the DOS50VDM directory for the .COM files as well as the CONFIG.SYS and AUTOEXEC.BAT files. On the brighter side, I know with OS/2 1.3, the BOOT.COM file would use two different CONFIG and AUTOEXEC files. It had one called CONFIG.OS2 and one called CONFIG.DOS, which it copied to the root of C: when you used the dual boot feature. I given some thought to this approach, but am finding it a challenge in a VDM. I could write a .CMD file to copy the correct CONFIG (and AUTOEXEC) files when I boot DOS 5.0 in a VDM, but I can't come up with a way to "back them out" when I close the VDM.

To execute DOS from your C drive, you must install OS/2 on an extended partition with Boot Manager. This leaves DOS "active" on the C drive.

Thus, OS2 2.0 does not support WINDOWS enhanced mode. The rationale for not supporting WINDOWS enhanced mode is two-fold: 1. To support WINDOWS enhanced mode operation presents severe system integrity exposure in a real multi-tasking system like OS2 2.0. WINDOWS can do it because it only does non-preemptive multi-tasking where only one application at a time is really running. 2. There are analogs of all WINDOWS enhanced mode services available directly from OS2 in WINDOWS standard mode. (in other words you don't need enhanced mode to get the same benefits in OS2 2.0 because there is so much DPMI and/or expanded memory available under OS2 2.0) Hope I haven't muddied up your understanding of this problem!

The last I heard, IBM was _considering_ adding this support, but I gather there are considerable problems with it. Windows Standard mode will serve most programs, which Win-OS/2 will provide nicely. If you really need 32-bit support, and if this is an in-house program, then the first thing that comes to mind is that you should look into converting it to a real OS/2 2.0 program, which should run better anyway.

Then when a person launches Paradox 3.5 from the Public applications group of a n OS/2 2.0 Requester, it checks to see if a PARADOX.SOM is residing on its C: drive (for instance C:\PDOXTMP - where we put the users PARADOX.CFG file), and if not it copies the OS/2 version down, sets the path and launches Paradox. Th is way DOS DLR machines are unaffected, and OS/2 machines are automatically updated to use the proper SOM file. I set C:\PDOXTMP as first in the path, and call PARADOX.EXE from the directory. The only side affect I have seen is i f you ask Paradox to make a table of active users, it lists the OS/2 users as with no name.

Primarily these are the DOS memory managers and mouse drivers. If these are the drivers that are failing try this. Assuming Boot Manager is installed and DOS is installed on Drive C and OS/2 is installed on Drive E. edit the CONFIG.SYS on Drive C to look like this: device=c:\dos\himem.sys device=c:\dos\emm386.exe noems device=e:\os2\mdos\himem.sys device=e:\os2\mdos\emm386.sys dos=high,umb ... etc ... Edit AUTOEXEC.BAT on Drive C to look like this: Prompt $p$g set path=c:\dos LH e:\os2\mdos\mouse LH c:\dos\mouse ... etc ... Now when DOS 5.0 is booted from Boot Manager, DOS will see the machine as a 386/486 machine and load the \dos\himem and \dos\emm386 drivers to manage memory. The \os2\mdos\himem and emm386 drivers will detect they are not running under OS/2. When AUTOEXEC.BAT processes the \os2\mouse stub recognizes it is not running under OS/2 and does not load thus allowing the \dos\mouse driver to load. When you load from a VMBoot session the \dos\himem fails since it sees no extended memory and \dos\emm386 fails since it sees protect-mode software already running. The \os2\mouse loads this time and the \dos mouse driver recognizes that a mouse driver is already loaded. There is a lot more information on this in the OS/2 Version 2.0 redbook Volume 2: DOS and Windows Environment - GG24-3731. Hope this has helped.

According to the detail sheets on MMPM issued by IBM, this software is supposed to provide multi-media extentions to the Presentation Manager!

Ref: Append at 05:23:43 on 92/07/17 GMT (by WZ00547 at OS2CUST) VDMA.SYS is the virtual device driver (VDD) which allows mutiple DOS and windows applications to access the DMA hardware as if each one had the machine to itself. It plays "traffic cop" and makes sure the DMA transfers are from memory below 16M and locked contiguous. It is loaded (at config.sys processing time) automatically so you do NOT want to include an entry in your config.sys for this VDD. (as you found out) As an answer to how to use it: What is it you wish to do that you think you NEED to use it? It should be there by default for all your DOS/Windows stuff.

A CD-ROM would be nice (even without MMPM) because many software packages are starting to come on CD.

The OS/2 and Win extensions use (nearly) identical application programming interfaces (APIs), which should ease the upgrade path (from Windows to OS/2) for developers. But the application still has to enable MM support. MMPM/2 only provides the extensions for PM, not for WINOS2. If you can find MS's MM extensions for windows 3.0, they should work. The soundblaster does have a microchannel model. If you are planning on business use of sound, you should get the IBM Audio Capture and Playback adapter. If you will be playing games, get the soundblaster (everybody supports it).

I've been lent an IBM ACPA card by by local SE and have been testing it. I can get the demo programs to work well under OS2-DOS, but don't quite understand other things. I've changed the outputs from my 3510-0001 CDROM - the RCA outputs that is - and moved them to the ACPA output. Consequently, no sound! I asked LINK Q&A about this, and was told that I need "drivers" for the ACPA in my OS2 config file! I've asked the SE about these. Now M$ BookShelf works fine in the CDROM, but never would give sound, under WINOS2. When I clicked on a sound icon, I got a window asking for M$MM extensions. So one of the systems people at the University let me a disk to try. However, it was for Win 3.0, and was not clear how to use the files. I tried putting a device statement in the OS2 config, but I hung the machine! Consequently, I assumed the new PM MM would be the software of choice when a program asks for MM extensions. I also assume this software will point any CDROM that requires MMex to the sound card - what ever it is! Note: Sherlock Homes keeps sending an error that an SB board is not installed. This I fear is a "hard coded" issue - and won't be solved by PMMM. Elliott M.

I have DOS 5.0 on the same partition as OS2 and have the system set up for dual boot between the two. In talking with our local IBM SE we both see the reasoning behind not providing backup and restore in a DOS session i.e HPFS file system and file name lengths etc.. would not allow a reliable backup for all files. My problem still exists though. We have been waiting for OS2 2.0 for many months to allow us to market a third party DOS based software mangagement system. We need OS2 to allow us to run APPC programs concurrently to provide communications between our customer and our retail outlets. We are budgeting to sell around 100 systems in 24 months. We are using 8557-049 and possibly the 8557-059 (57slc). As I mentioned, the DOS based software uses backup and restore as an integral part of day end closing procedures. I can't see us having to license a copy of DOS 5.0 for each system we sell just to backup DOS base files in a DOS Session of OS2. Has no one else had this problem?

MMPM/2 comes with a DOS virtual device driver for ACPA so that you can run DOS sound applications in a Dos box. The procedure for installing Windows extensions on top of MMPM is to let it install ACPA.DRV but DO NOT let it modify config.sys, since it will overwrite the os/2 driver with a windows driver and poor things will happen. 2. CD output directly to the acpa card. If you are using the media player for windows or MMPM/2, then you should be able to automatically hear the CD through the media player.

Perhaps, just perhaps, there is a difference here? Is "%" a percent sign? And is "%", the percent sign, what you are using in "%PATH%"? Is it ASCII character decimal 37 (hex 25)? Are you using a UK version of OS/2, the US version of OS/2, or are you using something else? What codepage are you using? What does a UK OS/2 manual say is the correct syntax?

The % character is indeed a percent sign, ASCII 25x, and it works fine as %1 %2 etc for command-line substitution. I'm still running a beta-test version of OS2v2 (6.177) but I've tried the same thing on 3 colleagues' machines, all running GA code, and they give exactly the same problem. The best suggestion I've had for fixing it so far is to configure my machine as a dual-boot machine and run real DOS from the second partition - One of my colleagues has this arrangement and %PATH% gets substituted properly in his real DOS session (but not in his OS2 DOS box). I guess I ought to install GA code anyway so maybe I'll blow my next week on doing that! Thanks for the suggestion, anyway.

I.e., a DOS session started from a boot diskette or a boot diskette image. You might also want to make sure that your DLR code is that the LAN Server 2.0 code. It is simplist to boot with a DOS 5 image and use the most current DLR (one that supports DOS 5).

The problem is with 123. In configuring the printer connection, try selecting "Using COM1". The menus of 3.1+ are confusing. When the menu offers choices, like "1 2 3 4 5 6" across the top of the screen, they are NOT saying LPT1 LPT2 LPT3. Pay close attention to the second line, which may change from "paralel 1", "serial 1", to "use LPT1" or "use COM1". The latter appear to be using the DOS standard interface for LPT1 or COM1, as opposed to attempting to control things directly. I'm not sure of the key sequence, but it should go something like /Worksheet,Global,default,device,interface. Good luck!

What happens when you run the following TEMP.BAT file: Echo %path% Echo %xxx% Set xxx=Hello Echo %xxx%;%xxx% ? The DOS command "PATH" or "SET" will display the current value of the path environment variable. What does it report? Perhaps your AUTOEXEC.BAT file is the culprit. The default AUTOEXEC.BAT that comes with OS/2 uses the PATH *command*, not the SET PATH= statement. It says: PATH C:\OS2;C:\OS2\MDOS;C:\ The online reference says "To delete the use of the PATH command, enter the command followed by a semicolon." Could your AUTOEXEC.BAT file have the string PATH ; in it? Perhaps the semicolon is in some column way off to the right of the display? Also keep in mind that the environment variables are local. If you open a DOS session, change the environment variables, then close the DOS session, then reopen a DOS session, you will find that the environment variables you changed were not saved across the sessions. One other "long shot" is that somehow the National Language setting of "United Kingdom" causes the "%" to have a different meaning. If you double-click on: OS/2 System System Setup Selective Install Click on the "Country" checkbox and press "OK" what does it display? "United Kingdom" "National" or "United Kingdom" "Multilingual"? Does changing this make any difference? If you double-click on: OS/2 System System Setup Country And look through the country notebook, are any of the separator characters set to "%"? Robert A.

Since windowing is done in a hardware graphics mode, some environments offer fewer colors when in a window, since PM requires certain colors in the palette willy-nilly, and hardware may be restricting the entire screen to a total of 16 shades. On an XGA, I cannot see any real change in the colors, although color 7 (white) _looks_ much dingier in a window, probably because it comes out the same as the desktop, which we instinctively identify as "grey". Try comparing the outputs of this QBASIC program. CLS FOR Shade% = 0 TO 15: COLOR Shade% PRINT STRING$(80, 219) NEXT An actual blink test seems to show little difference on my machine.

I have alot of experience with the DisplayWrite series. The effect you are seeing is the word processor changing video modes. In FULL screen it sees the monitor as EGA or VGA and will show true bold and underscore. When you make DisplayWrite a window it detects this change and thinks it is running on a CGA monitor. If you wanted you could set up the colors for the CGA and EGA/VGA modes. Go to profile, There is a setting for the system attributes, For the screen it will have three listings: APA (EGA/VGA) CGA colors MONO black and white You will have to set the colors for APA mode and CGA mode. This way when you change from FULL to WINDOW the colors will be the same. I have used DW5 for OS/2 and it too has the same problem. By the way if you call IBM DisplayWrite support you can get the newest release of Displaywrite 5 it is version 3.3 If you need the number just let me know Jerry Sitbon (718) 357-4369 ----- OS2DOS CFORUM appended at 19:45:41 on 92/08/04 GMT (by XXLLOR01 at TORVMCOP) Subject: Application can't write to screen (SCRN) Ref: Append at 23:33:09 on 92/07/31 GMT (by XXLLOR01 at TORVMCOP) Updating this APPEND myself since the status has changed.

Mine has a /A, and yours probably does to, which will cause this to happen. In an OS2 session enter HELP DIR, and see what is says for the parameter /A. This is what is causing the display you see, or at least on my system it is. In a DOS session, DIR /? will show you abrieviated Help, but it is not as complete as the real Help. The minus sign for the /A parameters is not shown for example.

This program transfers spectral data files from a UNIX ("IDRIS", actually) workstation to the PS/2. I recently switched the system from OS/2 1.3, running the software in the "penalty" box. The transfer software as well as the program ran fine in this configuration. Under OS/2 2.0, I am now having problems with serial data transfer. Most files seem to transfer O.K., after making some of the tweaks mentioned earlier in the FORUM (IDLE_SENSITIVITY, setting disk priority off, increasing speed by eliminating EMS and XMS, replacing COM drivers from OS/2 CSD), but on not so rare occasions I still get errors in the transfer. This does not appear to be a file problem, as using BOOT manager to Boot DOS 4.01, and then running the software under 4.01, the files transfer fine (and significantly faster). I believe that the communications run at 9600 baud. These communications problems appear to be the same in a DOS VM or in emulated DOS. Is there anything I missed? Any suggestions on how I might get this application running without having to resort to rebooting to 4.01 each time? (Incidentally, full screen or window did not seem to make any difference). The Software I'm running is Sprouse Scientific Systems FTIR search software, and the files are being transferred from a DIGILAB 3200 data station. (Not that I expect that anyone is familiar with this...) Any suggestions would be MUCH appreciated, as I am getting desperate at this time. I really need to integrate the applications for this user.

If not, I suggest you either get a serial card with a 16550 or, assuming your port currently has a 8250 or 16450, replace the existing UART with a 16550 (they are pin-compatible). Also, you should use the MODE command to set the serial port characteristics. Try putting this command in your CONFIG.SYS: CALL=C:\OS2\MODE.COM COMx,IDSR=ON,ODSR=OFF,OCTS=ON,RTS=HS,DTR=ON,BUFFER=AUTO The BUFFER parameter only applies if you have a 16550 UART.

I don't believe there is a BUFFERS session parameter. OS/2 is managing disk I/O and caching, so DOS BUFFERS is kind of pointless. Apparently you have an application that is checking DOS control block structures and (correctly or not) finding no BUFFERS. Applications that actually inspect the structure of DOS typically run into trouble under OS/2 because the OS/2 implementation of DOS does not look exactly like DOS. Try installing/running this thing in a VDM booted from a DOS diskette or Image file. That way you'll be running a "real" version of DOS and the required structures should be as your application expects. You will also have a CONFIG.SYS and AUTOEXEC.BAT specifically for that session and you can specify as many BUFFERS as you need. Mark Thompson - Coal Services Corp.

Figure out which adapters the DOS session does not need to use at all. Then specify MEM_INCLUDE_REGIONS C0000-CFFFF or D0000-DFFFF or whatever it takes to make a 64K ('10000'X) contiguous page frame available to EMM386. Don't specify any parameters on the EMM386 line in CONFIG.SYS.

I.e. for a FAT system the line: diskcache=240,48,lw ac:c worked best, by trial and error, on my 2.0 machine at home. (buffers= can be reduced with caching, i have 16 on mine.) The parameters affecting timeslicing default to about 3 times too large. Try: maxwait=1 timeslice=32,96 I know how you feel about the poor performance. It doesn't seem to make sense that an interrupt driven system should be slower at times than the single-threaded DOS that it replaces. And 2.0 definitely seems slower than 1.3, which we have on our servers at work. I think that there is something wrong with the disk drivers since I can hear the heads move a lot for even a simple operation. ->Rich ----- OS2DOS CFORUM appended at 17:52:37 on 92/09/08 GMT (by ABLI001 at OS2CUST) Subject: VM support for other than DOS, specifically AIX The support for VM boot disks in v86 mode seems to be fairly general.

Minix is the only variant of UNIX that I have heard of which might run in a DOS-session. You can run DOS, Dr-DOS, CP/M, and your reference diskette in a VDM.

I use th e DOS Network Version of Crosstalk with the ACSI NETBIOS interface to a LANACS server to do many communications things like logging on to BBS and doing downlo ads. I can also load up the DOS EBIOS command, redirect a COM port to the LANACS Ser ver, and then start up a DOS Comm. program( like Procomm Plus Net Ver.) that us es INT14 services provided by the DOS version of EBIOS. I have used this, but not as heavily as Crosstalk. And for OS/2, you can use ACDI redirection, and use the OS/2 REDIRECT command to redirect a OS/2 COM port to the LANACS server, and any OS/2 program that can use ACDI should be able to use the shared modem. The LANACS Server will also run under OS/2, and that is the way we are using it . I have had some dificulties trying to get LANACS to use the RTIC multiport c ards under OS/2, but we are working that issue out.

Besides backing-up just the files, OS/2 must also account for extended attributes, which DOS knows nothing about. If your users have a need to backup under OS/2 and restore under DOS, there are a couple of solutions: 1) Dual-boot to DOS or boot off a DOS floppy. Not very elegant, but it works. 2) Boot a VDM from a DOS diskette or Image file and run the backup there. You can find extensive information online concerning how to set up a bootable DOS diskette or Image file for OS/2. Check out the help for FSFILTER, FSACCESS, and VMDISK.

The problem is this: when you take a simple one page spreadsheet and try to print it in wysiwig mode the progress indicator jumps right to 19%, and within ten seconds or so reaches 49%, it then takes an additional TWENTY minutes running in the foreground to reach 82%, and then another TWENTY minutes before it actually comes off the printer.

The redirectors are called from the DOS kernel if the CDS indicates it is a network redirected device. Since the calls are issued by the booted DOS kernel the scope of that attached drive is only within that one VDM. No other session is aware of it's presents. To make the network drives visible system wide will require a VDD (Virtual Device Driver) for Lantastic. You will need to contact Artisoft regarding whether or not they are working on such a thing.

On rare occassions I have seen it run through the first burst of interrupts (I am using an interrupt-driven transmit design), then stall. My interrupt service procedure works fine in real DOS, and consists of the usual simple test of the interrupt identification register and a branch to an in/out of the data register depending on receive/transmit status.

Michael Nagy, Tampa (MNAGY at SPPVM1) ----- OS2DOS CFORUM appended at 20:36:28 on 92/09/18 GMT (by FULKGL at BCRVMPC1) Subject: miscellaneous I've only recently subscribed to this forum. Rather than answering one issue at a time, let me just make a large general response. Extended Attributes. Yes, DOS Emulation fully supports EAs. We use undocumented int 21h, ax=5703h and 5704h, to get and set EAs. Long file names. No, we do not have long file name support, just 8.3. Loadhigh from VMBoot session. There was a bug in FSACCESS that prevented Loadhigh from working properly in the VMBoot sessions. It has been fixed. Environment variable substitution. Currently we are DOS compatible. Environment variable substitution is only done in .BAT files. Dos command lines do not allow it. The OS/2 sessions allows substitution on both .CMD files and the command line. We are considering adding environment variable substitution to CONFIG.SYS processing and to the DOS command line. But it is only a proposal at this time. No decisions have been made, nor any code written. DOSKEY. I wanted to include DOSKEY function by default, but that would break DOS compatibility. So the best I could do is put the line in the default AUTOEXEC and REM it out. Obviously trying to give the user a hint of please take out the REM, and see what added function you get. Note, that I also gave you a sample DOSKEY macro, FINDFILE. DOS's BUFFERS= parmaters. DOS emulation does not have disk buffers. The values in the List-of- lists are assigned a default value of 0,0. If your program is being held up because it does like these values, you can try the following. But just be cautioned that their is no real buffers and your program had better not try accessing them. Try the following DEBUG sequence. a mov ah,52 int 21 es: mov word (bx+3F),14 es: mov word (bx+41),1 int 20 rcx 12 n fakebuff.com w q This will stuff the BUFFERS=20,1 values into the List-of-lists. Terminating a VMBoot session. DOS's EXIT command will not terminate a VDM for several reasons. It will not return to any caller before the last "COMMAND.COM /P" level. Even if it did DOS's kernel does not have a PDB for it to return to, so the kernel would crash. I've written a very simple DEBUG sequence to create a simple solution called EXIT_VDM. Don't ask how or why, but it will signal the OS2KRNL to kill the VDM. a mov ah,4D int 21 hlt DB 2,FD int 20 rcx 9 n exit_vdm.com w q Named pipes. Named pipes are supported. Simply open "\PIPE\name" to open the named pipe. At present the function to create the pipe and act as a server does not exist for VDMs, but VDMs can act as a client. The QBasic problem is caused by the fact that QBasic adds a drive letter to the front end of the open. We also have support for undocumented named pipe calls int 21h, ah=32h..3Ah. DosStartSession. The environment parameter is mute when it comes to VDMs. This is refering to things such as "SET PATH=". This parameter is not passed through to the VDM. Environments in DOS are created and managed by the user shell (COMMAND.COM). The DOSKRNL hardly knows of their existance. When COMMAND.COM is called from the DOSKRNL it creates an environment from scratch at that point in time. Altering DOS Settings outside of WorkPlace Shell's notebook. Sorry, but that doesn't exist yet. SYS2237 NPX Error. If a non-administrative floating point instruction is executed (ie. FADD), no floating pointing coprocessor is present, and the EM bit in CR0 is on, the system will hang solid. To prevent this from happening, we intercept the int 7 and issue the hard-error message. An application should use the Intel approved method of detecting a coprocessor's presents before it issues any non-adminstrative commands. Therefore, this is an application bug, not an operating system bug. Don't wait for PJ04878, because it was cancelled. Another issue is when will floating point emulation be available in v86 mode; I don't know. SYS2237 will disappear when it becomes available. Trap D. V86 mode makes calls to the OS2KRNL to perform some of the system services. Although we have tried to prevent any failures, such as traps, some have occurred. Traps have received high priority when reported. At this time there are no reported traps against DOS emulation that are not fixed. George L.

The "a" (assemble) command allows you to enter simple assembly language statements. The null entry returns you to the DEBUG prompt "-". "RCX" displays the current value of the CX register and allows you to change it. The value in the BX:CX registers will be the number of bytes written with the "w" (write) command. When you enter DEBUG without specifying a file BX and CX are 0 by default. Since I've assembled 9 bytes of code, BX:CX should be set to 0000:0009. The "n" (name) command allows you to name the destination or source input/output file. The "w" (write) writes the work to disk. The "q" (quit) exits debug back to the DOS prompt. I've suggested to our management that EXIT_VDM.COM should be included in the service pak diskettes. No decision on that has been made. On my long append I made a typo under "named pipes".

I went and found a copy on a local BBS (which uses author's releases and virus checkers) and tried it out. I usually have "pulse" running and noticed that cpu usage when DOS programs are started is always 100%; which is a bummer. I had never figured out settings which would actually reduce usage, even though the descriptions sounded like os2 supplied a solution. For those who want to experiment with this product, here are the 2 lines that I added to AUTOEXEC.BAT which seemed to work the best on OS/2: C:\tame261\tame-res C:\tame261\tame /freq:5,2 /win /dvaware /timerpoll Notice that I force it to act like windows is running (it says "unknown multitasker" otherwise, although it seems to recognize that DPMI is there.) The /dvaware makes it fake a desqview environment since a lot of software has hooks to multitask better there. The /timerpoll made it look for polling the timer in addition to the keyboard. Hopefully IBM will improve the options in OS/2 so that it will supply similar solutions in the future. ---- Note about an interaction: Up until I got DOS to reduce CPU usage, I had problems running John Ridges DESKPIC. He had a note in the latest version (DESKEXT2, I think?) that said he had made the screen saver work on 2.0, but not to use the background pictures. I then found out that running DOS machines made it hang up; apparentl y it starts a low priority thread and never gets any CPU time since the DOS mac hines hog it all. With CPU usage reduced, some of the screen savers work (other s still don't, but I just won't use them.) John: if you are out there, it will be nice if you get even only the static ba ckground pictures to work, but I do miss the fish hiding behind the windows. ->Rich Corbett; ABC Liquors, Inc., Orlando, FL (NASPA: CORBRIC7) ----- OS2DOS CFORUM appended at 02:45:28 on 92/10/03 GMT (by GORDER at RCHVMX) Subject: Length Limit on DOS SET PATH=. . .

Another way around the problem is to use the DOS SUBST command. Pick some large subdirectory names and substitute dummy drives for them. You can then put the dummy drives in your path statement to reduce the length of it, but not loose any of the subdirs being searched. This is illustrated below.

DOS usally truncates the env variables to 127 chracters, but DOS also uses "C" string processing (null terminated strings). So writing a program (or getting a shareware program) to go in and increase the size of the variable and terminating with a null char. shouldn't be to hard. Of course this is an *unsupported* function.

Ref: Append at 02:45:28 on 92/10/03 GMT (by GORDER at RCHVMX) The PATH or any other command line entry in DOS or DOS Emulation has a 127 character limit. That hard-coded limit is not likely to change any time in the future, because it would break DOS compatibility. That means every batch file line and every command line is truncated to 127 characters. I do have a proposed work-around for DOS Emulation to do work on, but it currently has a low priority. Batch files allow environment variable substitution, DOS command lines do not. So the first step is to allow DOS command line environment variable substitution. The second step would be a to change the PATH command so that it uses the raw input line rather than the parsed input line. This would make the PATH code much larger and more complicated, but would permit greater than 127 character input. Environment variables have no limit as long as they fit inside the environment space, which is limited to a maximum of 32K. Unfortunately environments are a very poorly supported object in the DOS world. There are environment editors, but none of them 100% guaranteed to work. I'd say many are 98% guaranteed, but none 100%. I can generate test cases that would break every one of them. I could add the support to MVDM, but that's even lower priority than the 2 ideas listed above. George L.

Ref: Append at 22:31:02 on 92/10/05 GMT (by ABLI001 at OS2CUST) REXX in the DOS box would be nice. Unfortunately I know of no plans to make that happen anytime soon. But that would not solve this problem. Since the environment is owned and managed by COMMAND.COM (not the DOS Kernel) the only safe way (100%) to change an environment variable is to go through COMMAND.COM. There are 2 safe interfaces to COMMAND.COM, the command line and int 2Eh. Both go through the same parsing code that limits input to 127 bytes. My current plan is to change the PATH code inside COMMAND.COM to look at the raw input line (ie. "PATH=%path%d:\util;") rather than the parsed command line that would already have the "%path%" expanded. For instance, I always have two 1-line .BAT/.CMD files for this purpose: 1STPATH.BAT: @path=%1;%path% ADDPATH.BAT: @path=%path%%1; But I still have the 127 character line limit. George L.

At work we have one called NETPATH, which is close to the length limit. And what I was saying about REXX was: we can already get the value and I suppose change the path (I haven't tried changing yet) in os2 cmd mode. e.g. curpath=value('PATH',,'OS2ENVIRONMENT') dummy=value('PATH',bigdir||';'||curpath,'OS2ENVIRONMENT') 'applicat' dummy=value('PATH',curpath,'OS2ENVIRONMENT') Of course for DOS you may give us a different value in the 3rd parm. ->Rich Corbett; ABC Liquors, Inc., Orlando, FL (NASPA: CORBRIC7) ----- OS2DOS CFORUM appended at 15:32:35 on 92/10/07 GMT (by GARTNERJ at FSHVMX) Subject: Memory Problem in OS/2 2.0 DOS Box I have the original 2.0 installed with no updates.

When the application is running under DOS 5.0 (real DOS), it runs fine. When it runs in a DOS full screen under OS/2 2.0, it reports 14 available file handles and then aborts. Under real DOS 5.0 the setting is: FILES=50. Under OS/2 2.0 the setting is : FILES=140. I tried to change the FILES setting in both CONFIG.SYS and in DOS settings, but it didn't solve the problem.

Try adding the executable name(s) to the DOS_VERSION setting. If DOS 5.0 seems to work, try this setting as an example: CLIPPER.EXE,5,0,255 (assuming CLIPPER.EXE is your executable). Every program in DOS (ie. DOS 5) or OS/2 or MVDM starts with a local Job File Table (JFT) of 20 handles. Irrespective of the FILES= or DOS_FILE settings. It is the applications responsibility to increase the size of his JFT. In DOS there is a documented function to perform this task, int 21h ah=67h. This function was introduced in DOS 3.30. DBASE IV would check the DOS version and only execute the int 21h ah=67h if the version number was 3.30 or above AND below 10.00. OS/2 2.0 reports as DOS version 20.00. As a result DBASE IV was not increasing it's local JFT size. Maybe Clipper 5.1 has a similar bug!? George L.

The granularity of the time is 976 microseconds. CX is the high-order word of the count. For example, if CX is 98h and DX is 9680h, a 10-second delay would be specified. I have found that some machines under DOS *DO NOT* support this function as it states here (typically phenix BIOS machines), but under OS/2 -- it works!! Also, since OS/2 traps this function, the processor is freed to do other operations in the machine other than waste cpu time in the VDM. A simple test of this is to load the same program with a ten second delay, into a VDM. First execute the one with the polling loop and watch the pulse monitor under OS/2, (it will stay quite high). Then run the same program but with the ROM BIOS call in it... The pulse goes down to nothing... OS/2 says: "You want to wait for ten seconds... I've got other things that I could be doing." BTW: OS/2 will always return to the VDM "on-time"..

You specify VDISK.SYS in your CONFIG.SYS. Details are in the online command reference (search for VDISK.SYS). DOS device drivers for block I/O devices such as RAM disks won't work under OS/2, but in this case you really don't need one since OS/2 supplies a working alternative. Robert A.
