Wire a custom cable that properly interfaces the GPIB-232CV-A
hardware handshaking protocol to the handshaking protocol of your
serial device.
Minimum Configuration Cable
The minimum configuration cable assumes that the DCE does not require
external hardware handshaking. The minimum configuration for a DTE
9-pin to DCE 9-pin cable is shown in Figure B-4. Figure B-5 shows an
equivalent 9-pin to 25-pin cable.
