Multi-Tech Systems, Inc. CDMA Wireless AT Commands (PN S000294J)
81
Ring Indicator Mode +WRIM
Description:
This specific command sets or returns the state of the Ring Indicator Mode. In pulse RI mode, an electrical
pulse lasting approximately 10µs is sent on the Ring Indicator signal just before sending any unsolicited AT
response in order not to lose AT responses when client tasks are in sleep state. Still in RI mode, when
receiving incoming calls, electrical pulses are sent on the RI signal.
In up-down RI mode, no pulses are sent before unsolicited AT response, and up-down signals are sent
when receiving an incoming call.
Values:
<n>
0
up-down RI mode
