OK ! I have to ask: how is it possible that with an application which is
a decade old, I could have down loaded and installed a very out of date 
version, just 2 weeks ago ?

My log shows:-
http://dosemu.sourceforge.net/mirrors.txt

So we see: some 'garbage collection needs to be done.
I've just wasted further resources navigating:
ftp.ibiblio.org/pub/Linux/system/emulators/dosemu/
 withgout finding the recommended version.

Perhaps someone can direct me to the URL of the *1.1.99.1*tgz ?
Please.

it means that the mirrors still haven't picked up the newest versions,
sorry I haven't checked them recently.
Have a look at www.dosemu.org -- there are more ways to find something.

Please don't punish me as a beta tester for your Ver 1.1.99.1 !
Just tell me how to use the stable version 1.0.2 to drive par-port(s).
Other users have done this.

That's were I started which led to the 'mirrors' which are not updated.

There are MANY ways to failure.   Lets try to reduce them.

Here's what I find:
1.  when I try to download Ver 1.1.99.1 as advised, I get spam in my face:
->>>         Browse SourceForge - Shop Thinkgeek - ...
...
->>>    [_] Send me photos of my matches. Plus uncover the secrets of
->>>    * Buy cool stuff from our network
->>>     Lowest Price: $96.99

2. AFTER you have unpacked the tarball its contents: README.bindist
 tells you how the unpack the tar ball ! ?

3. Similarly the script 'dosemu' which is only available after unpacking 
its parent-tarball, has code to (possibly) unpack the tarball ! ?
      tar -xzf $SYSTEM_INSTALL_PATH/dosemu-bin.tgz
 ....
      tar -xzf $SYSTEM_INSTALL_PATH/dosemu-freedos-bin.tgz

4. Following the apparently out of date (invalid) documentation
 with Ver. 1.1.99.1:
== select a new, clean directory; try as root:
# tar -zxf dosemu-freedos-bin.tgz
[root@localhost mydos]# ls
dosemu  dosemu-1.1.99.1-bin.tgz  dosemu-freedos-bin.tgz
# tar -zxf dosemu-1.1.99.1-bin.tgz

cd dosemu
[root@localhost dosemu]# ls
FDchange.log  README.bindist  Xfonts  bin  conf  dosemu  freedos  xdosemu
[root@localhost dosemu]# ./xdosemu

 Creating symbolic link for bootdirectory as /root/.dosemu/drives/c  <-- OK

./dosemu: readlink: command not found     <--? no such 'executable' ?
./dosemu: /../bin/dosemu.bin: No such file or directory
exec: /../bin/dosemu.bin: cannot execute: No such file or directory

---------------------------------
Indeed the command 'readlink' called from within script dosemu is 
unknown to my RH 6.2 installation.
 Perhaps this cause the problem of the existing bin/dosemu.bin
not being accessible ?

Try newest version dosemu-1.1.99.1, where you don't have to run dosemu as root 
for parport usage. Runing programs as root is always a bad advice.

Why can't su root ./dosemu ?

[easlab]

For the sole purpose of being able to use a DOS application which 
drives my par-port from linux, I installed 
dosemu-1.0.2-bin.tgz   and    dosemu-freedos.bin.tgz
to my red-hat6.2 to dir:
/home/crg/DOSEMU/dosemu
  which gave me 4 sub-dirs: conf, freedos, bin, Xfonts.

Several test on other DOS applications run OK.

But I can't run as root in order to access the par-port.
The various HOW2s refer to files which don't exist in my instalation. eg:
> ..........Thus you should
> not allow users to run a suid root copy of dosemu, wherever possible,
> but only a non-suid copy. You can configure this on a per-user basis

?! /etc/dosemu.user  does not exist 

I have edited the ..dosemu/conf/dosemu.conf  for:
$_ports  , but the problem is to be able to run as root.

Here's the trace of my failed atempt:
[crg@localhost dosemu]$ su root ./dosemu    <--- use this
Password:
==
  Your are logged in as user root. The local configuration within
    this DOSEMU installation is not intended for secure operation.
      You need to run this as normal unprivileged user.

Obviously also after logging in as root, I can't run dosemu.

Please tell what are the adjustments needed to drive my par-port.

Thanks,
