Description
ibsic asserts the GPIB interface clear (IFC) line for at least 100 µs if the GPIB board is
System Controller. This initializes the GPIB and makes the interface board CIC and
Active Controller with ATN asserted.
The IFC signal resets only the GPIB interface functions of bus devices and not the
internal device functions. Consult your device documentation to determine how to reset
the internal functions of your device.
