:D I just wanted to say that -d does nothing so -td works same as -t.
at the end -d -t == -t -d == -td ==-dt isn't it?

Key combos may be a problem, yes.
You can run "cat" and see what your key combos produce.
For example "Enter" and "Ctrl-Enter" produce the same newline,
which means making it to work the dos way is not trivial.

Yes in linux terminal both produces \x0a

anyway same dos exe i'm using is working fine with dosemu started with
-X so maybe it is possible.

Its certainly possible with -X, the problem exists only
with -t. So after you outlined it, I withdrawn my suggestion
about -t. -t is good to just run a bat file, which I thought
your use-case is. For interactive stuff it doesn't work well.

There is absolutely nothing wrong about it except that it is
just usually not needed for text-mode non-interactive stuff,
and the advantage of not using it is that you'll have all the
text still on your terminal after dosemu closes. The output
of your .bat can be redirected to the file with simple bash
redirection etc - this is just a better integration with your
linux environment, but nothing very important.

leaving any output in terminal is not important here because my batch
file ends with exitemu ;-)

If you use '-dumb' or '-td' (depending on version), then the
DOS output will stay on your terminal even after exitemu.
Unfortunately is seems dumb is not an option for you as you
are using colors and ascii drawing.


Anyway it is possible to use it without -X and change font/wndow to
large one. My current .desktop file looks like:

Terminal=false
Icon[pl]=gnome-panel-launcher
Exec=gnome-terminal --profile TEST --hide-menubar --command
"/home/cartoon/skrypty/run-kantor-kasa.sh"

This is a work in progress:
http://lists.jedsoft.org/lists/slang-users/2015/020.html
They added such support into slang and mc, but its very new.
For example I have fedora-24 and it doesn't yet contain these
features.
You can fill the ticket in dosemu tracker and maybe someone
will find the time to look into this sometime in the future.

Ok it's old but working. At work I prefer to use old and stable

This is a delay since the print data xfer ended, not started.

Thank you very much!

For future users what I did is:

$ cat run-raporty.sh
#!/bin/bash

socat -d -d -u pty,group=dialout,mode=660,link=/tmp/ttyCOM1,raw,echo=0
create:/tmp/ttyCOM1.txt &
SOCAT_PID=$!

dosemu -X -f "/home/cartoon/skrypty/dosemu-raporty.conf"  -E r.bat

kill -9 $SOCAT_PID
rm /tmp/ttyCOM1


and it's working just as I like11 Once again thank you for the HINT! :)

Hello!

i've got dosemu installed on ubuntu box. I've OKI dot matrix printer

Now if i'll try e.g.

$ echo test | lpr -l
the printer starts to print immediately.

But from dosemu if i'll try:

C:>echo test > lpt1:

it's working but there is 3-4 seconds lag before it starts to print.
Where can i look to fix it?

my dosemu.conf part:

$_lpt1 = "lpr -l"
$_printer_timeout = (10)

So why dont you reduce the timeout then?


The second thing:

i like to have COM1 (serial) port transmission redirected to reglar
file. I tried something like:

$_com1 = "/tmp/com1.txt"

but it's not working. Is it possible to catch serial transmission to a file?

Yes, but not as simple. You need to establish the pty link
with 'socat' program. But this feature is quite simple to add.

That's the way that lpr works under dosemu.  It's my understanding that the 
objective is to print a whole page at a time because that's how modern printers 
work.  Since most dos programs don't send a page end/page break, dosemu just 
waits for a few seconds to see if anything more is coming; if not the page is 
assumed complete and send it to the printer.
