LabView serial control

[mbone999@my-deja.com]

Hello,

I'm currently trying to use LabView for RS-232
communication. The thing is, instead of using
the standard hardware flow control method, I'd
like to be able to control the flow control lines
manually. Is there any way to set the values of
these pins?

Thanks,
M

As far as I remember: advanced/memory/Port-IO

With the Port-IO-Vi you can control every pin.

By the way: that works fine with Windows 3.1x, with Windows for
Workgroups and with Windows 9x. If you use Windows NT, you need the
"hwaccess.dll" too.

Viele Gruesse!

VISA will let you do this. There is a bit of a learning curve, it's
slightly more complicated than the standard serial port VI's but a whole lot
easier than using In/Out port. Once you learn to conform to the standard
style then it actually makes your diagrams straightforward and data-centric.

Also VISA is platform independent, at least it works fine on Win9x/NT. I
have had some trouble with Win3.11 though.
