IS-101 Voice Mode AT Commands

Table 25. Voice Mode Command Descriptions (Continued)

Command Default

Description

Event Reporting and Masking: This command selects which detection events are supported in voice mode. Each event is represented by a single bit of a four-digit hex number (see the following table). Setting an event number bit to 0 means that event is not reported. Setting a bit to 1 indicates that a detected event is reported. While the event settings affect all modes (that is, playback, record, and command modes), not just voice command mode, the mask can be changed each time the mode is changed. Not all events are supported in each mode. See the following table for supported events. This modem supports more features than an IS-101 Class C-compliant modem. (Class C is the highest IS-101 compliant modem, and Class A is the lowest.) See the following examples for more information.
