Hello.
I tried to communicate with one instruments by application made by Visual Basic 6.0 using gpib-32.dll.
I could write command by ibwrt32 API. But next I call ibrd32 API, VB freezes immediately.
Instrument engineer says that data is sent correctly.
I have ever communicated with many instruments by same procedure, but it is first time situation
like this. Instruments engineer says ATN signal line hand shaking( ATN uses command and data flow control) may not working corrently each other.
Is it possible that handshaking may not be matched with some instrument by gpib-32.dll or some version of this dll?
Thank you.
