DESCRIPTION
The EOI line is one of five bus management lines on the IEEE 488 interface. It is used by a Talker to indicate the end
of a multiple byte transfer sequence. The controller can change the EOI mode by programming the DAC488 from the
bus. In the K0 mode, the EOI line is asserted by the DAC488 on the last byte of every bus output string. In the K1
mode, the EOI function is disabled.
EXAMPLE

PRINT#1,"OUTPUT09;K?"
Line 2: Request EOI selection from DAC488.
PRINT#1,"ENTER09"
INPUT#2,A$
