According to the wine RPM description, Wine can do Win16 and DOS apps too. But I don't know much about their DOS virtualisation. Aitor run away from it, it's not maintained that much. FreeDOS + DOSEmu can perfectly run TC the last time i checked. -- ! diego, kde-il translation team, http://www.kde.org/il Please avoid sending me Word or PowerPoint attachments.

[Freedos-devel] new app: scrsave
Hi, I am releasing this app under public domain. What it does is quite simple: it saves the contents of the screen into a file c:\screen.txt, once every 3 seconds. I am releasing this code to public domain since: - GPL is too restrictive, and it is many times problematic for incorporating into commercial products. - I am having some problems, and I feel that if more people are exposed to the code, they will be able to fix it, or tell me what I am doing wrong. Problems: the app displays a char on the right upper corner of the screen, which indicates that is it working. I start the app, and in commmand.com it works. I type some commands (like dir of something similar) and I can see the commands output on the text file. However when I start prorams like turbo pascal or edit or dos navigator I still get the old command prompt on the text file. The funny thing is that I see in the right upper corner my app runnning. All the screen handeling was done by reading or writing from segment B800. In TP code it looks like this: Type VGA_Screen = array[0..25-1,0..80-1] of record letter: char; color: byte; end; Var Screen: VGA_Screen absolute $B800:; The I just read or write to this variable to read or write to the screen. If anyone has a better approach, please do tell. I also need to implement virtual keyboard input from a text file. I found function 5 of int 16h which can help me, however some tests I have run did not work: procedure send_key( ascii: char; scan_code: byte ); Begin asm mov ah, 05h mov ah, scan_code mov cl, ascii int 16h end; End; I send some chars to this function and then I did a readln. I expected to get the letters sent to this function and the ones I actually typed on the KB in the string. However I got only the ones I typed in the keyboard. The app can be find in: http://cucomania.homelinux.net/pub/dos/scrsave.pas http://cucomania.homelinux.net/pub/dos/scrsave.exe I compiled under TP 7.01 (the one from the french borland site they gace away some years ago). I can port it to C, and probably will in the future. -- diego, kde-il translation team Please avoid sending me Word or PowerPoint attachments.

Re: [Freedos-devel] Re: new app: scrsave
Saturday 08 May 2004 15:19,Eric Auer: Hi, I think you will be able to capture the screen in Borland IDEs by simply making your program check which screen PAGE is in use. You can find that information in the 0x40:xx BIOS data area. Public domain is okay - easier for people to use your code in other programs. But GPL does not limit people in reading your code either! But it limits them by not giving them perision to reuse this code in their projects. I dont like the virus effect of GPL. MIT might be a good idea... maybe next project. It only limits people in what license they may use for derived works. I dont get it... Page N is in B800:[80x*25*N] right? I tested it... (I made an arrays of screens, and printed all of them into a file. and still I can write to the first line in the screen ... so I think I am seeing page number 0... I will test again. And of course you could port it to Turbo Pascal 5.5, of which even the English version is available for free from the Borland community museum. Or to C or to Assembly language or whatever you want :-). TP 5.5... mmm... interesting... :) -- diego, kde-il translation team Please avoid sending me Word or PowerPoint attachments.

Re: [Freedos-devel] monitoring screen output
, 20 2004, 22:09,Arkady V.Belousov: No. Unfortunately, DOS itself calls INT28 too rarely (only when it waits onput to fill input keyboard buffer), so you should use other doors. Ie., for example, you should trap INT21 and, if happen some event (handler from INT1C sets some flag), then your main resident code may call DOS if DOS not called OR you in DOS, but DOS calls INT28. But wait from me too much answers, I'm not write extensive resident code. You should study, for example, libraries like TeSeRact, TSRtoo, AMIS (management library from Ralf Brown) etc. I did a readln in pascal, and was hoping to see my interrupt working :) this is not the case. DI Another thing: DI Looking inside the kernel in file chario.c in function: read_char_sft_dev, I DI see this code: DI if (check_break *pdev != syscon) DI check_handle_break(syscon); DI /* the idle int is only safe if we're using the character stack */ DI if (user_r-AH 0xd) DI DosIdle_int(); DI and also: DI http://www.ctyme.com/intr/rb-2739.htm I don't know what contained in this page. Just mention, which interrupt you mean. DOS 2+ - GET ADDRESS OF INDOS FLAG AH = 34h ignore that... me stupid... did not see GET. anyway, I see an if before. what does is the variable which is checked? DI Apparently I have to pass a pointer to a byte to the DOS and set that byte DI to 1? I think I am lost, that manual is not that usefull. :( ? again, ignore me, I am just half blind. I will look for the libs you mentioned, and I am also looking for demos in C (asm is too long :) Thanks again. -- diego, kde-il translation team Please avoid sending me Word or PowerPoint attachments.

[Freedos-devel] monitoring screen output
Hi all!
I need to write a program which periodically saves the screen contents into a
file. What I have done is trapping int $1C, and every 30 secs, run a 2nd
procedure which opens a file and saves $B800: to it. The problem is (that
I am stupid and forgot to pushf before calling the original handler :) that
when I open a file, and start writing to it, the emulator dies.
For those who lost me, I am compiling using the free French version of TP7
under DOSEMU and sometimes XP.
The relevant code is, the failure point is (as far as I know) the point marked
by {*}:
code
Procedure save_screen; far;
Var
F: file;
x,y: integer;
Begin
Assign( f, 'f:\screen.txt' );
ReWrite( f, 1 );
For y:=0 to 24 do
For x:=0 to 79 do
{*}
BlockWrite( f, screen[y][x].letter, 1 );
Close(f);
End;
Procedure my_timer; Interrupt;
Begin
PUSHF;
Call(old_timer);
If (tics mod 18) = 0
Then Case (tics div 18) mod 3 of
0: do_something;
1: save_screen;
End;
End;
var
x,y: integer;
begin
old_timer := get_int( TIMER_INT );
set_int( TIMER_INT, @my_timer );
readln;
set_int( TIMER_INT, old_timer );
end.
/code
If anyone knows what I am doing wrong, please tell me.
PS:
does the license of the FTP7 let you use it for commercial products? Can I
compile something with it and sell it?
TIA
