Ringing Indications
When the CTA 500dm detects an incoming call that it is allowed to accept, the RI pin is asserted (see ÒSerial Interface Control LinesÓ on page 56 for more information), and a text string is provided to the serial interface. The text string is repeated every 6 seconds until the call is answered (manually or automatically), disconnected by the caller, or if the CTA 500dm is reset (such as assertion of DTR if &D is 2 or 3).
Result Code
RING Appears when an incoming call is received.
