IEEE bus. This command instructs all devices on the IEEE bus to get off the IEEE bus.

A ABORT I/O
The ABORT I/O command causes the Interface Clear (IFC) bus management line to be
pulsed. By asserting IFC, the Micro488/p regains control of the bus even if one of the
devices has locked it up during a data transfer. ABORT I/O forces all IEEE bus device
interfaces into a quiescent idle state.
