Please advise if there is a better forum for this question...
I'm using Excel VBA with a VISA driver to control two instruments using TCP/IP sockets and raw SCPI. Recently, after installing the latest VISA drivers, socket connections to my devices began closing automatically after about 6 seconds of inactivity.
I can set a breakpoint on a line of VBA code following a successful line of communication, then watch the REMOTE control indicator on the instruments extinguish with no further action of the VBA code. The socket termination behavior is new, and the only change has been the VISA version update.
Is there a relatively new VISA driver feature that control a behavior like this?
