If you want to make your own cable to connect to some serial device, use the drawing of
the SLP pin assignments and the cable connection drawings in the previous section for
the required connections.  Hardware flow control lines must be used when communicat-
ing with the SLP using RS-232.  The flow control lines are not used for RS-422/485 com-
munications.
