Hello!
It seems once again that the uses of the parallel printer port as a general purpose I/O port have resurfaced. This time with me.

This application will be running on VEE5 and under Windows95, I came across in my archives copies of the two libraries that were written for VEE. One was originally written for VEE3 and Windows 3.11 (!) and the other was written for both Windows95 and NT, and the demonstration program was written more for NT then for 95.

Naturally I now need to know if anyone has found any working alternatives to what should called a matched pair of kludges. For those of you who want to know why I chose that much earlier release of Windows, it happens that the socket I/O object happens to work sending and receiving stuff from both Linux and Solaris 10.

Brief overview:

Windows Standard Mode: No kludging necessary, use x86 in and out instructions at will. I don't think it matters as VEE 3.12 requires win32s anyway and that won't run in Standard mode.

Windows 386 Enhanced Mode: Includes 3.11 & 9x (of which Me is one - the "Fake Windows" series). Processor runs in protected mode enabling "illegal instruction" traps however Windows allows x86 in and out instructions without interfering.

NOTE: The following version numbers in quotes are my own.
2000 reports version 5.0
XP reports version 5.1
Vista reports version 6.0
2003 et. al. are probably just different flavors of XP.
2008 et. al. are probably just different flavors of Vista.
Whatever else they are, they're definitely all NT.

Windows NT (the "Real Windows" series), all versions through 4: Hardware abstraction makes any IO impossible from any user application. Need native mode driver to dispatch IO. Use inpout.

Windows NT 5: Introduction of Windows Driver Model. NT4 drivers are supposed to work through backward compatibility, but many fail. Inpout still works.

Windows NT "6" or XP: No drastic changes.

Windows NT "7" or Vista: Account Control interferes with nearly *everything* that communicates with the outside world. Status of inpout unknown (by me).
If it seems to be not working, turn Account Control off (should be done anyway, as leaving it on makes your PC practically unusable anyway).

Why don't they just use "sudo"? Bill's warriors have lost it IMO. MS is too big and clunky to do any good any more.

> and receiving stuff from both Linux and Solaris 10.

I'd be more concerned with ZFS on Solaris. If you've got any clients using this, you should probably try to get them to switch to Ext3 instead. Judging from the traffic on [ZFS-CODE], it looks like this file system is in flux & has been for some months now.

Also, beware of ReiserFS. With SUSE switching to Ext3 by default, there's no good reason to run ReiserFS any more. Sure the community is carrying on with Reiser4, but with the probable conviction of Hans Reiser for the MURDER OF HIS WIFE(!) I don't think this one's got any future at all. From a technical standpoint, all Reiser versions are just Yet Another File System anyway.

It probably won't be long until NTFS is available as a general purpose option on many distros. Read support is certainly excellent and write support is probably good enough as long as any NTFS volumes aren't mounted on Windows (heheh).

Still, unless there's some compelling reason NOT to run Ext3 I don't see the point of practically any other FS, with the possible exception of UnionFS or AUFS. Provided of course you can afford to keep growing your storage.

Hello!
I agree with the issues surrounding EXT2 and EXT3, and my Linux workstation is using EXT2 only. I gave up even thinking about ReiserFS about the same time that issue surfaced.

My Solaris setup happens to be wearing whatever default file system they chose to use, I think its the same one that the BSD ones use.

Now regarding your ideas regarding windows, I agree across the board.
I'll keep pinging along for others however.

I recently installed Solaris Developer 10<something> & I got ZFS (the whole reason I installed was to get ZFS in the first place). It's not like it's going to fall apart or anything, just if it is ZFS watch out for upgrades.
They're into territory that can potentially break your whole disk.

OTOH, this is Sun and I'm sure they're not going to release anything that can mangle your file system

It's just that I see them pondering redesign of some of the basic constructs of the system and to me that just smells like big trouble for previous users.

They're just more open about it. Microsoft did the same exact thing between Windows 2000 & XP, but nobody noticed because they managed to pull it off without causing major problems. It was a serious headache for me though & thanks to inconsistent implementation I use a really ugly hack to account for it.
