I prefer newsgroups which are basically public domain,
publicly available, and uncensored as far as I know.

But yeah - I signed up to os2world as well, but I think I
was supposed to get a verification email that never arrived.

I'll chase it up if/when required.

Ok. I have had success in getting my old development
environment up and running. I can once again produce
native OS/2 executables using Open Watcom and my
own C library.

And I had instead an idea to replace Odin, with the
limited scope I have in mind. Because I already have
much of the infrastructure in place (e.g. code to load
a win32 executable), as part of PDOS/386. I largely
just need to replace the not-very-big kernel32.c with
one that does OS/2 calls instead of PDOS calls. There
are a few other things.

I have confirmed that when I build my own OS/2 native
executables, the escape sequences take effect.

So if I go the route of writing a public domain, somewhat
minimal, win32 environment for OS/2, I know that the
escapes will get through.

However, I still have a problem with keyboard input. I
need to get ANSI escapes - or at least - something -
when I press the different cursor keys. Otherwise my
version of microemacs 3.6 (also public domain - that
older version) won't work.

So I wrote a test program, and if I build it as a win32
executable (using pdpclib) and run it under "pec", all
the cursor keys generate a x'e0'.

If I instead build an OS/2 native executable (also with
pdpclib), I don't get any input at all.

The "keys off" command doesn't change either of
the above.

PDPCLIB is using this code:

C:\devel\pdos\pdpclib>git diff stdio.c
diff --git a/pdpclib/stdio.c b/pdpclib/stdio.c
index 685e3e4c..f6b837e6 100644

ie doing a DosRead from handle 0.

I thought there might be a DosDevIOCtl that governs this
behavior, so I went looking for the documentation.

I was surprised that this was all I could find online:

http://www.edm2.com/index.php/DosDevIOCtl

which is insufficient. I actually need three things for
a fullscreen editor like microemacs:

1. Cursor keys to come through with unique codes.
2. Echo switched off.
3. Line buffering switched off.

On MSDOS I can use INT 21H AH=44H to change those
last two things. But without documentation I don't know
if the equivalent exists in OS/2. I know what is required
in Windows too.

PDOS/86 is an 8086 OS, so it would be a replacement
for OS/2's DOS, and not be useful regardless.

But PDOS/386 has the infrastructure to do 32-bit for
Windows, so as above - I can potentially do what I want
in an OS/2 window.

Although - I just realized while typing this that I could
possibly install HX into a DOS window to run everything.

I come close to being able to do that in Freedos+HX
already.

It took me a while to realize that fat32.ifs already came
installed in ArcaOS and all I needed to do was

format /fs:fat32

instead of the fat that you see with "format /?".

And now long filenames work perfectly fine on the FAT32-formatted disk!

I think the VIO thing is what is swallowing the ESC character.
And what I need to do is switch to standard streams.

Any thoughts welcome!

Thanks. Paul.
