/UT

The /UT command is a low level IEEE command which sends the UNT command to the

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

AABORT 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.
