If your serial device does not use the same hardware handshaking protocol
as the GPIB-232CV, you can either use a minimum configuration cable and
use XON/XOFF handshaking (if necessary), or wire a custom cable that
will satisfy the GPIB-232CV hardware handshaking protocol. The
connections for a minimum configuration cable are shown in Figure B-2.
The GPIB-232CV connector is on the left. (Assumes that the DCE's
handshaking is satisfied internally.)

If your application requires a custom cable, review your serial device's
RS-232 characteristics and build the cable to perform the desired functions.
