Multi-Tech Systems, Inc. CDMA Wireless AT Commands - PN S000294C 101
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
1: pulse RI mode
