ISU AT Command Reference Modem Overview

Below shows a sample command structure of an AT command:

2.5 Responses

A result code is sent to the DTE in response to the execution of a command. It may also result from other

conditions such as an incoming call (e.g., RING). Responses returned as a result of a query are called infor-

mation responses.

Result codes can be represented by text if the ISU is in verbose mode or with numbers if in numeric mode.

The command ATVn informs the ISU whether to respond in verbose or numeric mode. The table below

shows the difference in format between these modes:

2.6 Command Execution

The execution of a command string follows a left-to-right execution of each command followed by the

reporting of a result code for the entire string.

2.7 Conﬁguration Settings

The ISU allows the DTE to conﬁgure the communication parameters.There are three types of conﬁgurations:

active, factory default and stored.

The active conﬁguration is the set of parameters used during phone operation and can be changed by the

DTE through AT commands.

The factory default conﬁguration is stored in permanent memory (i.e., ROM). These settings can be recalled

at any time by using the AT&Fn command.

The DTE can also store its own settings using the AT&Wn command. These are the stored or user-deﬁned

conﬁguration. This conﬁguration can be loaded as the active conﬁguration upon phone powerup by entering

the AT&Yn command.

Most of the conﬁguration settings are part of the “S-register” locations. “S-register” is the term used by

Hayes-compatible modems for a speciﬁc physical location in memory.
