Hi PG Student,

There are several useful documents online:

KB 2PGCBGT0. Programming VISA Events in Visual Basic

KB 2HH9BUQS. Where Can I Find Text-based Programming Examples for VISA?

I have also attached a simple program that demonstrates how to do serial instrument communication in Visual Basic (uses Visual Basic 6.0). The example was written to communicate with a NI Insturment Simulator, communicating with other instruments should be possible by modifying the example. The example uses 9
600 baud, 8 data bits, no pairity and hardware handshaking.

Hope these will be enough to get you started. Best of luck!
