Assert interface clear.
unsigned int ibsic (int ud)
ibsic
ud | Board descriptor |
Function Return | The value of Ibsta |
ibsic asserts the GPIB interface clear (IFC) line for at least 100 µs, then unasserts IFC. Asserting IFC unaddresses all devices on the bus and makes the interface board CIC.
The IFC signal resets only the GPIB interface calls of bus devices and not the internal device calls. Consult your device documentation to determine how to reset the internal calls of your device.
