4.3.1 RS-232 

When the RS-232 interface is selected, the use of hardware handshaking 
(control and monitoring of modem signal lines) is user definable. If no hardware 
handshaking will be used, the cable to connect to the port is as shown below: 

 

RS-232: Modem Connection 

This type of connection is required between the module and a modem or other 
communication device. 

 

The "Use CTS Line" parameter for the port configuration should be set to 'Y' for 
most modem applications.
