LACS Status Condition

LACS indicates whether the GPIB interface is addressed as a Listener. LACS is set when the GPIB interface detects that its listen address (and secondary address, if enabled) has been sent either by the GPIB interface itself or by another Controller. LACS is also set when the GPIB interface shadow handshakes as a result of the ibgts function. LACS is cleared when the GPIB interface detects the Unlisten (UNL) command, its own talk address, Interface Clear (IFC), or that the ibgts function has been called without shadow handshake.
