5.2.2 Configurable STOP Mode Protocols
You can configure the protocol to be used in STOP Mode, based upon the configured
serial port (RUN Mode) protocol. The Run/Stop protocol switching is independently
configured for each serial port.
The RUN Mode protocol setting determines which choices are available for STOP Mode. If
a STOP Mode protocol is not selected, the default STOP Mode protocol is used. For
details, refer to COM1 and COM2 Parameters in Section 3:.
5.2.3 Serial Port Pin Assignments
5.2.3.1 COM1 (RS-232, 9-pin Subminiature D Connector)
This port has a 9-pin, female, D-sub connector with a standard pin out. This is a DCE (data
communications equipment) port that allows a simple straight-through cable to connect
with a standard AT-style RS-232 port.
The CPE310 provides the DCD and RI signals to support point-to-point protocol (PPP).
