Command Reference Manual 1. INTRODUCTION 1.1 OVERVIEW This manual describes the host command and responses for the following Conexant modem families: SmartSCM™ Modem Device Set SmartACF™ Modem Device Set SmartACFL™ Modem Device Set The commands and responses are implemented in controller firmware for specific modem models. Additional configuration and implementation information is available in release notes and/or readme files that accompany product firmware release.
Command Reference Manual 1.1.4 ConfigurACE II for Windows Utility Program The PC-based ConfigurACE II for Windows utility program allows the OEM to customize SmartACF and SmartACFL modem firmware to suit specific application and country requirements.
Command Reference Manual 2. SYNTAX AND PROCEDURES The command and response syntax and procedures generally conform to referenced recommendations and standards. Since these recommendations and standards describe characteristics universal to a large installed base of modems to a maximum degree, there may be syntax and procedural differences due to extensions and behavioral differences in implemented commands, parameters, and responses beyond that described in these recommendations and standards.
Command Reference Manual 2.2.4 Repeating a Command Line If the prefix "A/" or "a/" is received, the modem immediately executes once again the body of the preceding command line. No editing is possible, and no termination character is necessary. A command line may be repeated multiple times in this manner. Responses to the repeated command line are issued using format of the original command line.
Command Reference Manual 2.4 Extended Syntax Commands 2.4.1 Command Naming Rules Both actions and parameters have names, which are used in the related commands. Names always begin with the character "+". Following the "+", from one to 16 additional characters appear in the command name. These characters will be selected from the following set: A through Z (IA5 4/1 through 5/10) 0 through 9 (IA5 3/0 through 3/9) ! (IA5 2/1) % (IA5 2/5) - (IA5 2/13) .
Command Reference Manual 2.4.2.3 Compound Values Actions may have more than one subparameter associated with them, and parameters may have more than one value. These are known as "compound values", and their treatment is the same in both actions and parameters. A compound value consists of any combination of numeric and string values (as defined in the description of the action or parameter).
Command Reference Manual 2.4.4.2 Parameter Set Command Syntax The definition of the parameter indicates, for each value, whether the specification of that value is mandatory or optional. For optional values, the definition indicates the assumed (default) value if none is specified; the assumed value may be either a previous value (i.e., the value of an omitted subparameter retains its previous value), or a fixed value (e.g., the value of an omitted subparameter is assumed to be zero).
Command Reference Manual 2.5 Issuing Commands All characters in a command line must be issued at the same data rate, and with the same parity and format. The modem will ignore any command line that is not properly terminated. The modem may consider 30 seconds of mark idle time between any two characters as an improperly terminated command line. In this case the modem may or may not generate an ERROR message.
Command Reference Manual 2.7.1 Responses There are two types of responses that may be issued by the modem: information text and result codes. Information Text. Information text responses consist of three parts: a header, information text, and a trailer: 1. The characters transmitted for the header are determined by the V command. 2. The trailer consists of two characters, being the character having the ordinal value of parameter S3 followed by the character having the ordinal value of parameter S4. 3.
Command Reference Manual 2.7.3 +: Information Text Formats for Test Commands In general, the format of information text returned by extended syntax commands is described in the definition of the command. The modem may insert intermediate characters in very long information text responses in order to avoid overrunning DTE receive buffers.
Command Reference Manual 3. DATA COMMAND SET 3.1 COMMAND GUIDELINES The commands used to control and report modem operation in data modem mode are defined in this section.

Command Reference Manual 3.2.8.3 +ITF - Transmit Flow Control Thresholds The +ITF command determines the flow control thresholds used by the modem for transmit data from the DTE. This optional compound parameter allows the DTE to determine the input buffer size in the modem for data on circuit 103 (transmit data) from the DTE, to control the thresholds used for flow control of such data, and to control how often the modem reports to the DTE the number of octets in this buffer.
Command Reference Manual 3.2.9 Diagnostic Commands 3.2.9.1 #UD – Last Call Status Report #UD is an action command requesting reporting of logged operation events. It does not take parameters and must be the last command in the command line. The modem logs aspects of their operation for each call, and saves these results until cleared by one of the following events: 1. Power off. 2. Hard reset (e.g., negate DTR with &D3 set; reset button). 3. Soft reset = ATZ or AT&F. 4. ATD command issued. 5.
Command Reference Manual Command Syntax In response to this command, the modem will report one or more lines of information text as defined below. Information text format conforms to V.250; each line is preceded by a pair, and terminated by . (CR and LF characters may be changed by writing new values to the contents of registers S3 and S4, respectively.) The modem may generate a single line or multiple lines, followed by a standard OK final result code.
