Globally release all visa instruments

[Steve_Block]

I ran into a problem where I was locked out of an instrument. Is there a way to have a program globally release all visa instruments or reset a GPIB card?

What do you by "locked out"? What do you mean by globally "releasing" instruments?

[Steve_Block]

Disconnecting all connections that the program might have on reserve.

[smercurio_fc]

That didn't explain "locked out".

You can use VISA Find Resource to get a list of VISA sessions, and then VISA Close to close them all. Whether or not this "unlocks" you is debatable since you haven't indicated what you mean by "locked out". Depending on what you mean, you may need to assert/deassert REN.

I'll have to see if the Ren line is what needs to be done because when I get locked out, visa close does not work.
