RJ-45 terminal
cable
Figure 21 shows how to wire a cable to connect a standard VT100-compatible
terminal to an asynchronous (RJ-45) port. Some terminals are fitted with a
DB25 female connector rather than a DB25 male connector. In this case the
cable should be fitted with a DB25 male connector.

Modem cable Figure 22 shows how to wire a cable to connect an asynchronous (RJ-45) port to
a modem.
