The descriptions apply to all these modems with any differences between modem product families noted. Refer to Modem
Firmware Release notes for commands applicable to modem firmware.
ATi, ATL, ATF, and ATFL models support error correction and data compression (ECC) performed by the host CPU and
communications software for Windows using the enhanced Rockwell Windows Protocol Interface (RPI or RPI+™) and
WinRPI host software module.

AT commands Section 3
S-Registers Section 4
Fax Class 1 commands Section 5
Fax Class 2 commands Section 6
Voice/Audio commands Section 7
AT Command Summary Section 8
The AT commands are implemented in microcontroller (MCU) firmware for specific modem models. The support for a
command category is identified by modem model in the modem designer's guide. Additional configuration and
implementation information is available in release notes and/or readme files that accompany MCU firmware release.
