Hello !
If you have compiled the IPX-Protocoll into your Server, it is possible,

It says in the README.txt that lredir doesn't work with FreeDOS because
FreeDOS doesn't have a working redirector yet. Presumably Novell networking
also won't work with FreeDOS for the same reason.
You could try DR-DOS from www.calderathin.com/dosemu/index.html instead
of FreeDOS.

Subject: 5250 card unable to find
General Posting for help.............................
I am using caldera 1.2 & 1.3 which installs
with Caldera Dos v7.02 using DOSEMU v 0.66.7..
I have one requirement of Dos under Linux,
That is to run a Dos 5250 emulator program.
The program runs operates is own ISA
emulator card at port 0x368 at mem D000 ..
The program runs flawlessly and connects to
the AS/400 under MSDOS..DOS in WIN 3.1..
DOS in OS/2 or even DOS in WIN-OS/2..
All on the same machine..
However in Dos under LINUX I get the error
message ..UNABLE TO FIND 5250 CARD..
In my dosemu.conf I used ports { 0x300 0x3ff }
& D000 mem seems clear..
My Adaptec SCSI card is 0x340-0x35F
SB16 card is DMA 3 at 0x330-0x331
Parallel port lpt1 0x378-0x37f
** All else is above or below & is FREE **
The program requires no config settings or
drivers,, the program takes care of all.
The card is from MicroIntegration
http://www.miworld.com
They support WinDoze primarily and DOS
only under the usual DOS enviorment.
LINUX is not in their vocabulary.
Any ideas

Hi Maurice,
as freedos dosn't yet support the network redirector code and as far as I
know, net.exe uses the network redirector, I suspect you need an other
DOS.

Floppy bug in 0.98.6 and 0.99.10 - keyboard die
Dear,
I tested new releases of your dosemu. It is nice, that it became
really working.
I have 2 floppies in 0.98.2 both worked fine.
Then I tested 0.98.6 and 0.99.10. After I do
"dir B:\" or "dir A:\"
then everything is correct, but my dos keyboard do not work from this
point.
(If I have dos -k switch then I have to reset). The bug seems to be
same.
Do you have an idea how to fix it.
2, You reported, that DOSEMU do not work with quattro pro v 2.0.
I tested it, and quatro makes some strange video tests. I obtain

How to convert dos to unix text files?
dos2unix if you have it. Or perl -pe 's/\r$//' for a pipe, or perl
- -pi.bak -e 's/\r$//' filename1 filename2 etc to change files in place.
Or load the file in vim, :set notx, and save and exit. You could
probably figure out some way to do it in pure sh if you try hard.

Subject: DOSemu slows system / SYS_166?
Hi *,
I've installed dosemu-0.99.10.0 on my RH5.2 box, the kernel
upgraded to 2.2.5, and started xdos, with in the configuration file:
$_rdtsc = (on) # if possible use Pentium cycle counter
$_hogthreshold = (100) # 0 == all CPU power to DOSEMU
$_com1 = "/dev/vmodem" # e.g. "/dev/mouse" or "/dev/cua0"
This xdos seems to slow down the system much, even when at the DOS
prompt doing nothing: dragging a window on my K6-2 333Mhz 128Mb slows
down alot [gfx card: Matrox G200], it looks like it spends a lot of
time in kernel space since it is not traceable with top.
strace -p1347 (xdos pid) gives some strange results:
read(12, 0x81a4e99, 128) = -1 EAGAIN (Resource temporarily unavailable)
SYS_166(0x1, 0x8106d44, 0x71000, 0xfff8eff1, 0x804bd00) = -1 ENOSYS (Function not
implemented)
SYS_166(0x1, 0x8106d44, 0x71000, 0xfff8eff1, 0x804bd00) = -1 ENOSYS (Function not
implemented)
gettimeofday({924722631, 925637}, NULL) = 0
read(12, 0x81a4e99, 128) = -1 EAGAIN (Resource temporarily unavailable)
SYS_166(0x1, 0x8106d44, 0x71000, 0xfff8eff1, 0x804bd00) = -1 ENOSYS (Function not
implemented)
SYS_166(0x1, 0x8106d44, 0x71000, 0xfff8eff1, 0x804bd00) = -1 ENOSYS (Function not
implemented)
gettimeofday({924722631, 926267}, NULL) = 0
read(12, 0x81a4e99, 128) = -1 EAGAIN (Resource temporarily unavailable)
etc.
[root@k6 fd]# ls -l /proc/1347/fd/12
lrwx------ 1 root root 64 Apr 21 21:30 /proc/1347/fd/12 -> /dev/vmodem
..so it's polling the COM port for no reason. Someone knows why?
After removal of the offending com line in /etc/dosemu.conf, the
system stays just as slow, but strace now gives:
SYS_166(0x1, 0x8106d44, 0x70000, 0xfff8fff1, 0x804bd00) = -1 ENOSYS (Function not
implemented)
SYS_166(0x1, 0x8106d44, 0x70000, 0xfff8fff1, 0x804bd00) = -1 ENOSYS (Function not
implemented)
SYS_166(0x1, 0x8106d44, 0x70000, 0xfff8fff1, 0x804bd00) = -1 ENOSYS (Function not
implemented)
SYS_166(0x1, 0x8106d44, 0x70000, 0xfff8fff1, 0x804bd00) = -1 ENOSYS (Function not
implemented)
gettimeofday({924723197, 781803}, NULL) = 0
etc.
It seems like this SYS_166 is the offending system call. Anyone knows
what SYS_166 is supposed to do?

Rutger.

Yes and no. Believe there is a difference in that unix uses just
a LF to terminate a line while dos most often uses a CRLF.
And the CRLF makes the text look weird. You can correct
this with vi, tran and I believe I have a utility called
dos2unix.

Subject: the difference between dos & unix is terminator
the difference is:
from caldera's site....
File type This option allows you to control how the
file is saved. For example on a Unix
machine you may want to translate a DOS
file (a file which terminates each line
in CR/LF characters) and have it saved as
a Unix file. By default a file will be
saved in the same mode as it was loaded.
The options are as follows:
Normal Save file in same mode as
it was loaded with.
Text Lines are terminated in a
LF character only.
Binary Lines are not terminated
with a CR or LF character.
DOS Lines will be terminated
with a CR and LF character.
(Note that no Ctrl-Z will
be appended to the end of
the file even if one was
supplied when the file was
read in. The terminating
Ctrl-Z is a hangover from
MS-DOS 1.0 and is no longer
need in text files for
DOS).

He is talking about the fact that ms-dog files use a cr and an lf to
indicate a new record. You can easily strip the extra carriage returns with
perl, or there are dos utils too.

You are correct. In addition, DOS text files also have a trailing control-Z.

$_hogthreshold = (1) gives all power to Linux (see doc/README.txt)
and with this I see a load of 0.05 on my machine, when idling on the DOS
prompt.

xdos eats 'X-power' (counts to the CPU load of the server), because
it has to refresh the screen quite often, much more then other X
applications (except real video of course;-). The config value to play
with is
$_X_updfreq = (5)
However, if you make the refresh rate big (value small), you eat more
X-power, if you make it too small (value big), you get a noticable delay
when the X-server has to wait for the X-application to finish some action.
It may depend on the X-server used though.

Yes, _quite_ a lot. Though it drops kernel priviledges and uses userspace
pagetables, it doesn't really return to the _32-bit_ userspace code while
in vm86(). It's a special case not 1:1 comparable with normal userspace.
And while in vm86() the CPU time apparently counts as 'kernel time'.

The reason is you configured to use it, and depending on what serial
drivers / TSRs you have, there is no other way as to poll.

It's the heart of vm86() ;-) and it's returning -1 on 99.99 % of its calls.
Why the strace / libc maintainers after over 2 years could not cope with
finally knowing what this 'strange' syscall 166 does, is out of the scope
of my knowledge ;-)

There is the dos2unix util. also, what I am constantly editing is HTML
(etc), created by others in something like wordpad. The ^M is generated
at end of line or when return is entered.(referencing above statement)
I use this command to globally delete these characters:
:g/<control v><control m>/s///g
save file.
it tells it to globally search (file) and replace (s=substitute) ^M with
nothing. end global search.

Try GNU recode: `recode latin1:ibmpc' for Unix->DOS,
`recode ibmpc:latin1' for the other direction. This fixes
both CRLF/LF and diacritical characters. On my system
`dos2unix' and `unix2dos' are shell aliases to the above
commands.

there is about 10 ways to do this, but by far the easiest way that
I've seen is use pico
open the file with pico and then save it, you may have to add a
letter and delete it though but this removes all those nasty M's in
the file :)

You presumeably want to explicitly allow direct access to the port - which
that line *doesn't* include and to ensure that DOSEMU maps the memory
address above onto your card (using 'hardware_ram')

IMHO (for legal reasons) you have to use the URL
http://www.calderathin.com/dosemu/index.html
And there you can see the license conditions.
> 7.03 for all users of DOSemu (commercial users included).
You should read the license details _very_ carefully. My comments:
^^
1. This only applies to the URL referenced by the 'Click Here to Begin
Download' link on the page entitled 'DOSEMU HDIMAGE'
and you _must_ use this site, no mirrors allowed.
They obviously want to keep the number of downloading people small,
because
a) the image is bloated to 7 Mbytes (zero padded), though it need
only to be about 1 Mbytes (dosemu can cope with 'empty tail').
b) it even isn't compressed by default
(Make sure to use wu-ftp's features to force on-the-fly
compression which will result in a 400 Kbytes only download.
... though, this maybe the first violation of the license
because you then are not using the download button;-).
c) no mirrors are allowed and no ones are available which contain
the file, ... though the FTP server directs you to use mirrors
if it reaches the limit of anonymous users.
(For sure not all of the estimated 8 million Linux users will be
able to download it. Even if you can suck 1Mbyte/sec from the
above site, it would take 2 years to pass each user its copy.)
2. It is only allowed to be used in the combination: Linux & DOSEMU.
Which makes it hard to track bugs (you are not allowed to run
it native) or to use it on multiple boot installations.
3. you are not allowed to 'redistribute in any fashion'
('any fashion' also applies to putting it on your intranet archive or
to copy it to a second machine of your own).
4. you _need_ to download the hdimage for _each_ individual machine
you want to use it on (this is a consequence of (3)).
5. You are only allowed to make _one_ copy of the hdimage and this
only for backup purposes. Its unlike you can handle this on
Unix systems, where backups normally are handled generation wise
and you will force the 'have to backup' state after each run
of dosemu.
6. You are not allowed to extract files to a Linux-FS, such as to
make use of DOSEMU's comfortable bootdir feature.
(this is a consequence of (5)).
Conclusion: 'violating' the license is more likely than with any other
proprietary DOS and the intention behind the license seems to be mainly a
marketing thing (which is legal) rather then a real support for DOSEMU.
I refuse to make any reference on dosemu.org or even within the DOSEMU
distribution to the above URL unless the license conditions do change
significantly. ... especially the redistribution and copying conditions.

The MSDOS version of the clas software was created using the Watcom 386 C
compiler. The resulting programs make use of the PC's extended
memory and can be configured to use virtual memory.
The program requires a PC-AT 386 or 486 with at least 2Mb of memory.
The setup for extended and virtual memory use is discussed below:
- ---------------EXTENDED MEMORY CONFIGURATION FOR PC------------------
The pc version uses the DOS/4GW extended memory manager supplied with
the Watcom 386 C compiler. The memory manager executable, dos4gw.exe,
is supplied with the clas software. It is called during program
startup, and so must be locatable using the PATH environment variable.
The dos4gw.exe program uses the environment variable DOS16M in order to
choose an appropriate real- to protected-mode switch technique. In case
the default operation does not work on your computer, change the
switch mode settings with the following command:
set DOS16m=value
Do not insert a space between DOS16M and the equal sign.
The table below lists the machines and the settings you would use with them.
Many settings have mnemonics, listed in the column "alternate Name", that
you can use instead of the number. Settings that you must set with the
DOS16M variable have the notation req'd in the first column. Settings you may
use are marked 'option', and settings that will automatically be set are
marked 'auto'.
status Machine Setting Name Comment
- ------ -------------- ------- --------------- ---------------------------------
auto 386/486 w/DPMI 0 None Set automatically if DPMI is active
req'd NEC 98-series 1 9801 Must be set for NEC 98-series

req'd OKI if800 15 None Must be set for OKI if800
option IBM PS/55 16 None May be needed for some PS/55s
The following procedure shows you how to test the switch mode setting.
1. If you have one of the machines listed below, set the DOS16M environment
variable to the value shown for that machine and specify a range of extended
memory. For example, if your machine is an NEC 98-series, set DOS16M=1 @2M-4M.
Machine Setting
------- ---------
NEC 98-series 1
Fujitsu FMR-70 5
Hitachi B32 14
OKI if800 15
Before running DOS/4GW applications, check the switch mode setting by the following
procedure:
2. Run PMINFO and note the switch setting reported on the last line of the display.
(PMINFO.EXE is provided with the simulator). If PMINFO runs, the setting is usable on
your machine.
3. If you changed the switch setting, add the new setting to your autoexec.bat.

- ---------------VIRTUAL MEMORY CONFIGURATION FOR PC -------------------
In order for the virtual memory capability to operate properly, the PC's
environment variables must have a defined variable DOS4GVM, with options to
define virtual memory paramaters. If the DOS4GVM environment variable
does not exist, the virtual memory capability does not operate.
The possible parameters are:
MINMEM The minimum amount of RAM managed by the VMM. Default is 512KB.
MAXMEM The maximum amount of RAM managed by the VMM. Default is 4MB.
SWAPNAME The swap file name. Default is DOS4GVM.SWP on the current drive.
DELETESWAP Specifies that the swap file should be deleted.
VIRTUALSIZE The size of the virtual memory space. Default is 16MB.
In general, use the following format for the DOS4GVM environment variable:
set DOS4GVM= [option[#value]] [option[#value]]
As an example, the following line in your autoexec.bat file will enable an
8MB virtual memory swap file with automatic deletion of the swap file:
set DOS4GVM=deleteswap maxmem#8192

It sounds like you have the line
$_dpmi = (off)
in your dosemu configuration file (usually /etc/dosemu.conf)
you need to change "off" to some number, say 2048 or 4096

No - the ports line is wrong. I think it should be
$_ports "0x368"
also if you only need to access 8K at 0xd0000, you could
change the hardware_ram line to
$_hardware_ram " range 0xd0000 0xd1fff "

I'd like to know whether anyone else is experiencing this problem:
DIR does not always give the same file list on a lredir'ed

In my case, there are 300+ files. Sometimes all the files are

one of just a few combinations of files that is available to list
or execute.
I have tried this with 2 Windows servers and 3 different DOSEMU
clients, with DOSEMU versions ranging from 0.66.7 to 0.99.11.
All of the Linux clients are using kernel 2.0.36, libc5, and

using gcc 2.7.2.3. The Windows machines run Win95 and Win98.

Hi People
Is there an opportunity to have NWDOS7 or NWDOS7 Programs inbound to LINUX.
I consider to changeover to LINUX beeing a DOS addict but forced to handle a
graphical shell as WIN311 for several purposes as Internet access and
scanning, picture modeling and works and so forth the development of which
got stuck in DOS development issues . I am absolutely no lover of WIN95/98
tending to avoid the handling around with this. By the way I think Billy
Gates's politics to be obsolete and am not willing to submit to his
objections.
The entire WIN98 got to go to the trashbin. All the WINdows systems are
lightyears away from working as stable as a NOVELL NETWARE 3.12 /NWDOS7
combination which owns the only fault not beeing designed to do graphical
jobs as the mentioned. So WIN is far away of being safe enough for my
purposes.
The Only thing is that I hold lots of DOS programs and databases which all
work fine. And graphical formats like *.GIF/*.PCX/*.BMP/*.JPG etc.
So is there a way to have them still run under LINUX way like in OS/2 ?
What can be done?

Hello
I'm lookin for how a blind user can use Linux with adaptive technology.
most of those screen access programs work under DOS and so i set up

anyway.
The problem is however how to use linux via dosemu. I tried dosnet.o
but it fails to load witch lots of complaints about unresolved symbols.
So, is there any other ways to communicate between dosemu and linux
kernel. For example to make a virtual serial connection where COMx: on
dosemu side is connected somehow to Linux serial device. After this any
terminal emulator could be used.

absolutely, im working on a project right now using linux serial devices
on a digiboard from dosemu. its pretty simple. all you have to do is edit
the /etc/dosemu.conf file and look for an entry like:
$_com1 = ""
and you simply change the com port setting you want to include the linux
device name. for example:
$_com1 = "/dev/cua0"
would be the equivalent of com1 from a real dos session.
hope this helps.

I tried _com and serial keywords with no success. The problem is little
differrent. I'll give an example:
Say i have configured com1 at the rear panel to be com1 in dosemu. Com2
is /dev/cua1 and agetty is running on it. I'll connett com1 and com2 with
null modem cable and run terminal emulator on dosemu.
Question is how to do this without the cable but still using comport at
dosemu side and agetty or similar program on the other end. At least
stdin, stdout and stderr on the linux side should be connetted to this
serial port.

It sounds like you have a problem similar to one I'm working on. I'm
trying to connect a telnet session to a program running in DOSEmu that
uses the com port/modem for input/output.
My approach so far (to avoid using null modem cables), is to use pseudo
tty's. They are devices that come in pairs like "/dev/ptypN" and
"/dev/ttypN". Where N is a single hex digit. You should be able to run
agetty on "/dev/ptypN" and tell DosEmu to use "/dev/ttypN" as the com
port (I havn't actually done it this way myself). Make sure you use a
psuedo tty that is not already in use (telnet connections use psedo
tty's).
I have been able to run a program that attaches stdin/stdout to
"/dev/ptyp9" on my system, and told DosEmu to use "/dev/ttyp9" as com 1
(DosEmu has to be started after "/dev/ptyp9" is opened by the other
program). Then I have been able to do things like "copy autoexec.bat
com1" and get the output on the other end. Unfortunately, that's about
all I've gotten it to do.
I'm still experimenting with this myself, so hopefully someone here can
help us both out. Maybe this will give you something to work with at
least.

Subject: Serial ports and c++ 'outp'
Greetings all,
I have a problem to do with a c++ program written for dos, which makes
heavy us of an 'outp' (dos system/library call? - I have not seen this
before) to communicate with a serial device. 'outp' appears to write
directly to a port address (along the likes of 0x3f8,9,a,b,c etc). I
assume that because it uses this call that setting $_com1 to a value will
not be of any use, and so I need to define a list of ports that dosemu
will allow to be directly written to.
I do not find any evidence of these calls failing. In fact, if I turn on
enough dosemu debugging I can see that port read and write calls are being
made, yet the dos program fails to recognise that the device is on the end
of the line. The program works extremely reliably under standard dos.
Communication with the COM? ports works fine with other programs when I
set $_com?, so, I was wondering if anyone knows of something else I can
try, or how I can write to the COM? devices from dos using some more
standard call that doesn't attempt to write directly to the hardware.
Thanks,
Mark.

Subject: More 5250 emulation on Dos Fun
Dave,
Thanks for helping!
Take a look One last time at my situation..
I have this particular 5250 emu program running on the same
machine now in OS/2 v. 3 & v. 4 , also Dos in OS/2, also PC Dos 7,
also MSDos 6.22, also Msdos 5, also DRdos 6.............
All with a bare 640k enabled no ems or extended mem..
no drivers of any type in the configs. ( THIS TRUE of THE DOSs )
The only OS I can't get this program to run in is Dos 7 from
Caldera on the Linux DosEmu, which is where I really want
it to run.
So, now with the mem at D000 free, I no longer get the error
message: UNABLE TO FIND 5250 CARD....
Now it JUST LOCKS & HANGS DOSEMU with no recovery
except to close the session.
I checked the DOS Session with mem /d
to get the read outs below..
And further down I did the same for LINUX using lsdev and sysinfo
commands..
As you can see memory D000 and port 0x368 are free
I know this is a lot to read but before I gave up I wanted you to see
I am baffled for good reason!!!!!!!
