Instrument driver and NImax

[Rina95]

Hi,

I'm having an issue with a driver I wrote for an instrument.

When I communicate via NImax, the instrument responds as it should, but when I send the same string to the same port with a VISA in a VI it doesn't respond.

Can someone please point out the problem?

Thanks a lot!

Almost every time someone asks this.  They forgot to shut down the interactive session in max...  you can't have 2 programs trying to use the same VISA resource.

Of course,  we could be a lot more specific if you supply a few details and some code....
