Most PC serial ports also require a cable with a female DB-9 connector.
Terminal connections will vary, requiring either a DB-9 or DB-25 connector, male or
female.
Serial cable options between a switch or router and a PC or terminal are shown in
Figure 9.
Note: As indicated in Figure 8 and Figure 9, some of the wires should not be
connected. If you do connect the wires that are labeled "Reserve”, you might
get unexpected results with some terminals.
