Program a GPIB-VXI/C with NI-VISA

You program a GPIB-VXI/C using the same function calls you would use to program any instrument in NI-VISA. You can perform message-based communication using viWrite() and viRead(). You can perform register-based communication using viInX(), viOutX(), viMoveInX(), and viMoveOutX() functions.
