If your serial device does not require or use the same hardware handshaking
protocol used by the GPIB-232CV-A, you have two options:
•
Use a minimum configuration null modem cable which does not
support the hardware handshake lines and use XON/XOFF software
handshaking (if necessary). To create a minimum configuration cable,
connect the signals shown in bold italics in Table B-3.
