Re: Switching in and out of fullscreen dosemu session?

[Raphael Tennenbaum rtennenbaum@xxxxxxxx]

yes, I'm sure sw.cmd requires Windows or OS/2. I just have a feeling
the issue is more one of how dosemu integrates with Gnome (or KDE). I
believe it is no simple matter for a desktop to fork over the focus to
plain ol' VGA; in fact under evey distro I've used the only real way to
get VGA, apart from dosemu, has been to log out. clearly this issue is
akin to those raised by the latest release from Redmond, but I also
witnessed deterioration in virtual VGA support with the last release of
eCS (=what they call the vestige of OS/2 still being marketed). nor am
I at all convinced it a matter of bitness, since 64-bit Linux supports
full-screen dosemu -- see http://en.wikipedia.org/wiki/DOSEMU, which
suggests to me that furnishing support to legacy full-screen DOS
applications isn't really very difficult at all.


I'm pretty sure Alt-Tab is the default switcher in Gnome and KDE, but I
could be wrong, since I tend to install Compiz straightaway, which
replaces the switching capabilities of the desktop in wholesale fashion.
 I guess it could be that dosemu in full-screen mode intercepts those
switchy keystrokes quite intentionally; the key combo to which I've
assigned another "ring application switcher" in Compiz also fails to
shell out from a full-screen dosemu session.

 Hi Rafe,

I haven't been using dosemu lately and my memory of it is a bit rusty,
but I do know that Alt-Tab is a Windows function for toggling among open
application "windows," and the Alt-Tab key combination is not reserved
for the same purpose on the Gnome or KDE (or X-Windows?) desktops
running in Linux. Also, some of the U2 routines are specific to Windows
and/or OS/2 (as I recall, you can see which ones by examining the U2
registry directly), and some of your own customizations may be
Windows-specific, too. I know Robert will correct me if I'm wrong, but I
think SW.CMD requires Windows.


Not that these are insurmountable hurdles. I suspect it would be
possible to modify your XyWrite installation to be fully compatible with
the different requirements of dosemu or dosbox, but I think it might
take a lot of time and patience. Might be well worth the effort in the
end. Meanwhile, Ctrl-Alt-F may be your best bet for toggling between
full screen and windowed Xy on a Linux box.

Subject: Switching in and out of fullscreen dosemu session?

I used to use XyWrite fullscreen under OS/2 but for a variety of reasons
gave it up. now I have been playing around with it under dosemu, where
it works handsomely, & hoping to tweak it.

is there a way to shell to the Linux desktop out of XyWrite the way I
used to under OS/2, using RH's superb SW.CMD? standard dosemu way to
return to the desktop is by invoking Ctrl-Alt-F to switch between
fullscreen and windowed sessions -- which okay, but adds a couple of
steps. I suspect it's not feasible -- if I start a plain old dosemu
window, resize it to fullscreen, and hit Alt-Tab, it simply beeps
instead of switching from the VGA console -- but just wonder if anyone
knows for sure.
