Looking at the manual on the HP 59306A, it says of the EOI line "Not
monitored or driven, terminated by resistive network". This rather
suggests to me it will make no difference whether the EOI is asserted or
not and so whether I open the device with
dd=ibdev(0, gpib_address, 0, T3s, 1, 0);
dd=ibdev(0, gpib_address, 0, T3s, 0, 0);
will make no difference.
