Serial comm. under WinNT4.0

[Holger Decker]

My application (including serial communication) works fine under Win95, 98
but I can't establish an communication under WinNT 4.0 Workstation (SP5).
What can I do??

Thanks

My first inclination would be to check to make sure that the serial port
you are trying to initialize has any errors on the NT machine. Check
the error number coming out of the Serial Port Initialization VI and see
if it isn't 0. A number other than zero indicates an error. There may
be something else using the serial port.

If you right click on the Serial Port Initialization VI and bring up the
Online Help, it will tell you what the valid numbers for serial ports
are for Win 95, 98, and NT. (They're all the same.)

I think you all ready tried this but I will tell you any way.
Check that the file Labview.ini has the line where the ports are configured.

I hope this helps you.

Just to let you know I use NT4 SP4,SP6 and the serial port
works fine and I haven't made any special adjustment. I just
reinstalled NT4 SP6 yesterday, installed my app and its running.
I use the serial port COM1 at 19.2.

Ooops, I haven't tried it, and there aren't line with port configurations.
But these lines aren't in my Win98 PC too. And how can i insert these line
(or what I have to type in these lines)?

There's not enough information here.

Is this all on the same machine with multiple booting?

Have you tried manually talking to the instrument via Teraterm or some other
serial terminal to verify hardware functionality?

Have you tried booting the machine from a DOS boot floppy with a DOS serial
terminal program on to rule out software conflicts?
