CML Specific AT Commands

Command

Description

@Bn

Ring Detection

Instructs PIC to detect BT or Bell ringing on a modem’s Ring Detect Line.

Syntax: AT@Bn<CR>

Modifier Usage

n=0 BT ring detection (default).

n=1 Bell ring detection.

@En

Evaluation Mode

Informs PIC which mode we will be operating in.

Syntax: AT@En<CR>

Modifier Usage

n=0 Selects Modem Mode (default).

n=1 Selects Test Mode.

@Fn

Test Functions

Syntax: AT@Fn<CR>

Modifier Usage

n=0 Return the status of the following digital inputs:-

IRQN1 (Bit 0), LV1 (Bit 1), IRQN2 (Bit 4), and LV2 (Bit 5).

n=1 BER measurement. (Not available in the current firmware revision).

n=2 BER Test points (Returns status of input and sets outputs high).

n=3 BER Test points (Returns status of input and sets outputs low).

n=4 CD LED On.

n=5 CD LED Off.

n=6 Simulate Ring Burst.

n=7 Simulate Ring Silence.

@Mn

Modem Focus

Informs PIC which modem should have the AT Command focus. All

subsequent AT Commands are directed at the modem with the focus.

Syntax: AT@Mn<CR>

Modifier Usage

n=0 Directs all subsequent AT Commands to Modem One (default).

n=1 Directs all subsequent AT Commands to Modem Two.

@RR

CMX6x4 Device Reset

Resets the CMX6x4 device for the modem with focus.

Syntax: AT@RR<CR>
