Figure 45: Pin wiring diagram for a standard DB9 male to female terminal cable.
While the asynchronous port (on router models with one asynchronous port)
has a DCE female socket, the router’s internal electronics regard the port as
DTE. Signals displayed using the SHOW PORT command therefore have a
DTE perspective. The internal DTE pin roles are listed in Table 36 on page 85.
