If you do not have a null modem cable, you will need the
following (see Figure 7-8 on page 7-31):
• One standard DB9 female-to-DB9 male serial cable.
• One DB9 male-to-DB9 male null modem adapter, or
both of the following:
• One DB9 male-to-DB9 female null modem adapter
• One DB9 male-to-DB9 male gender changer
Note A gender changer looks exactly like a null modem
adapter. It would be a good idea to label them so you
don’t get them confused later.
The top diagram in Figure 7-8 shows the simplest connection,
using a male DB9-to-male DB9 null modem cable. This type
of cable is probably not commonly available. The bottom
diagram shows a connection using standard, off-the-shelf
cabling and adapters:
