"set rights" serial port windows

[stefan!]

Hello,
this is not really an labview question,
but it is of importance, when you want to work
under windows XP (and probably also under WIN NT
and W2K) without administrator rights or if you
want to distribute your application to another
machine where you don't have administrator rights.

I was not able to configure the com ports under WIN XP
without admin privileges.
Who knows how to set the rights for users on a
WIN XP machine, to be able to configure the
serial ports.

Regards, Stefan

Hi Timo,

thank you for the link!

Here on my XP machine it is quite different, e.g. under file properties there is no

security tab:womansad:

If I want to set the right for a file or a folder I have to use "cacls.exe".

E.g. to  be able to work with labview 6.0.2  under my XP installation as a normal user

I had to give the following command (as a administrator):

cacls "C:\Programme\National Instruments\LabVIEW 6" /e /t /g ZSW119\spofahl:f

So the command for the max config file would be:

cacls C:\Programme\National Instruments\MAX\config.mxs /e /g ZSW119\spofahl:w

But the problem remains the same, you are still not allowed to configure the com-ports

I forgot the quotes:

cacls "C:\Programme\National Instruments\MAX\config.mxs" /e /g ZSW119\spofahl:w

has the normal user read/write access to the NI folder?

what kind of visa version you use, since visa 3.2 there should be no errror "An unknown error occured while ...."

That should only happen if you have formatted the harddisk as FAT. In that case individual file security settings are not really possible under Windows as FAT has no concept of file security.

With Windows XP, it's only important what format the SYSTEM disk is.  Even if all other disks are formatted NTFS, if the boot partition if FAT, there'll be no security options whatsoever.

As far as I know anyhow.

You are probably right here. But the opposite won't work. If only the boot partition is NTFS you won't get file security to the individual file level on FAT formatted drives.

That's true too of course.

Hi Timo,

the answer is no. I had to the the rights properly. And newer had the

errar message: "An unknown error occured while ...."

This is not the problem.

My question is:

How can I set the rights to be able configure serial ports for normal

users on an XP machine.
