Re: Fw: [fd-dev] Dosemu - X windows

2002-12-02 Thread Alain M.
  I just got in touch with the manteiner of DOSVNC and here is
  hi reply. This surely is interesting for the freedos project as
  thare is allways someone who wants to develop a grafical
  interface.
 
 Well it's a bummer that he does not have the code, hopefully he can
 recover it and post it since it would be nice for somebody to move on
 with the project.

In fact the sources were online all the time. I just downloaded them :)

 Sorry, I don't get it, so do you mean that you have a DOS program that
 displays in your screen your remote linux console??? That must be dead
 slow...

I never used it, but all that I have heard about it says that is very fast.
The trick is sendind down drawing primitives or somethin like that
and not the actual bitmap

 Hi, according to Andreas, if you use the LZ algorithm or something
 similar and just compress your text mode screen buffer and send it
 (or send a diff from the version 1/10 second ago, even), you get
 a rather fast program-independend copy of your screen which you can
 send for example through a serial cable to your Linux or anything
 else that decodes the data. I think text mode is okay for many things,
 and as said, it is fast.

Well you can certainly run dosemu (and hence DOS programs) remotely.
The way it works is that
* DOS programs write to the text mode buffer at 0xB or 0xB8000
* n times per second, (n=5 by default), DOSEMU examines the text buffer
and tells the contents to the Slang library.
* the Slang library can then compare the screen contents with the old
state, and generates terminal escape sequences to update the screen.

It depends on your CPU how long this takes. It's quick enough for me.

Re: [fd-dev] Dosemu - X windows

2002-11-23 Thread John M Harrison

Hi All,

  It's probably just a matter of time before there is a Linux compatible
X server for DOS. With the sources available and with the GPL someone
just has to get the spark and a little time :))

  I assume that a 'basic' Xwindow server is relatively simple? At least I
recall someone writing that somewhere? Someone on this list has to know
;-)

  It would be nice to just turn on a FreeDOS box and have X come up, ready
to go. You could make some nifty networked DOS picture frames out of old
computers :)  Turn them on and the slide show begins. You could even add
sound :)

  warm regards,
  john

 As far as I know there are no DOS Xservers other than possibly
 desqview/x.  There is dosvnc that allows you to access a remote GUI
 session on server. I have played with it a bit to access a Linux box and
 Windows systems across a network.
