Interrupt call in Win32 Application

[kid joe]

Hi,

Is it possible to use inline asm to make intrrupt calls in Win32 appl. for
reading some hardware information such as reading port's status register,
etc? Any restrictions or Impossible?

I need to talk to the LPT port directly in Win98/SE, or at least need to get
current status of the port(printer). - Paper out, power off, etc.

Any information will be appreciated.

Joe

PS. 3D in the glasses has been fixed. Thanks for the suggestion.

PPS. If you still don't like the sig, just ignore it, live and let live.
Thanks.

No

Impossible

That was the bad news.

The good news is that you can use the printer port
using the windows api. Look in

http://www.lvr.com/parport.htm

for a very comprehensive encyclopedia about the printer port.

Windows 98 runs in a system where there is no protection against
programsz talking directly to the hardware. In any other
versions of windows (2000 upwards) that will not work

You are not allowed directly interact with the hardware in a modern
operating system unless you are writing a device driver. If you want to
figure out printer status under Windows, I'm sure the Windows API has an
appropriate set of function for your application to call -- that's the
purpose of an API.

If you are not actually connecting a printer to the LPT port (who does
that anymore? Don't you use USB?), then you should be more specific in
your request -- and direct them to an OS-specific newsgroup.

Hi Jacob,

Thanks a lot for the advice, that looks like a website with plenty of
information.

By printer port to you mean lpt1?

Now that printers run off a usb usually, how do we update our bag of tricks
accordingly?

By asking in a Windows group where they know about Windows. Or reading
the MSDN documentation.

No, I will ignore *you*, and I suspect most other people here will do
the same, though I'm sure the resident trolls will be glad to
*pretend* to help you. If you want your questions answered, use a
shorter sig.

I actually have useful information in response to your question.

It's not a sig. It's ASCII art, for which there's a own newsgroup
dedicated to it: rec.arts.ascii
Post it there one time, if you like.

You know what: I might be going to ignore you at all. It's not
just because of the sig...

More emotional blackmail.

Especially when we all know that the "useful information" KT is so
cruelly witholding is "get lost and ask the question on a Windows
group".
