USRobotics Command Reference Introduction Overview This manual describes the commands and responses for ® host-processed (HSF or SoftK56) modem families. The commands and responses described herein are implemented in HSF drivers V6.02.00 and subsequent. Additional configuration and implementation information is available in release notes and/or readme files that accompany product software release. The .INF File contains exact application unique information and default values.
USRobotics Command Reference Introduction - 2
USRobotics Command Reference 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.
USRobotics Command Reference character may not appear in the body. The modem can accept at least 80 characters in the body. The termination character may be selected by a user option (parameter S3), the default being CR. Command Line Editing The character defined by parameter S5 (default, BS) is interpreted as a request from the DTE to the modem to delete the previous character.
USRobotics Command Reference Parameters may be "set" (to store a value or values for later use), "read" (to determine the current value or values stored), or "tested" (to determine whether or not the equipment implements the parameter, and the ranges of values supported).
USRobotics Command Reference If the "=" is used, the new value to be stored in the S-parameter is specified in decimal following the "=". If no value is given (i.e., the end of the command line occurs or the next command follows immediately), the S-parameter specified may be set to 0, or an ERROR result code issued and the stored value left unchanged. The ranges of acceptable values are given in the description of each S-parameter.
USRobotics Command Reference consists of either a numeric constant or a string constant. Numeric Constants Numeric constants are expressed in decimal, hexadecimal, or binary. Decimal numeric constants consist of a sequence of one or more of the characters "0" through "9", inclusive. Hexadecimal numeric constants consist of a sequence of one or more of the characters "0" through "9", inclusive, and "A" through "F" inclusive.
USRobotics Command Reference Action Commands Action Execution Command Syntax There are two general types of action commands: those that have associated subparameter values that affect only that invocation of the command, and those that have no subparameters. If subparameters are associated with a command, the definition of the action command indicates, for each subparameter, whether the specification of a value for that subparameter is mandatory or optional.
USRobotics Command Reference code and terminates processing of the command line. If the modem does recognize the action name, it returns an OK result code. If the named action accepts one or more subparameters, the modem sends an information text response to the DTE, prior to the OK result code, specifying the values supported by the modem for each such subparameter, and possibly additional information. The format of this information text is defined for each action command.
USRobotics Command Reference In case of an error, all previous values of the parameter are unaffected. Parameter Read Command Syntax The DTE may determine the current value or values stored in a parameter by using the following syntax: +? The modem responds by sending the current values stored for the parameter to the DTE in an information text response. The format of this response is described in the definition of the parameter.
USRobotics Command Reference 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. The modem will ignore any characters received from the DTE that are not part of a properly-formatted command line.
USRobotics Command Reference parameter unchanged; • Issue the OK result code, and leave the previous value of the parameter unchanged; or, • Issue the OK result code, and set the parameter value to the valid value nearest to that specified in the command line. The description of each command specifies which of these three techniques is used to handle invalid parameter values for that command or parameter.
USRobotics Command Reference Result Code Parts Result codes consist of three parts: a header, the result text, and a trailer. The characters transmitted for the header and trailer are determined by the V command setting. The result text may be transmitted as a number or as a string, also depending on a the V command setting. Result Code Types There are three types of result codes: final, intermediate, and unsolicited. Result codes are described in Section 3.4.
USRobotics Command Reference duplication of basic format result codes specified in TIA-602. Following the "+" character, the name of the result code appears; result code names follow the same rules as command names. Extended syntax result codes may include the reporting of values. The definition of the result code specifies whether or not values are appended to the result code, and, if so, how many, their types, and their assumed default values if omitted. Data/voice Modes.
USRobotics Command Reference For example, the following are some examples of value range indications: (0) Only the value 0 is supported. (1,2,3) The values 1, 2, and 3 are supported. (1-3) The values 1 through 3 are supported. (0,4,5,6,9,11,12) The several listed values are supported. (0,4-6,9,11-12) An alternative expression of the above list.

USRobotics Command Reference Data Command Set Command Guidelines The commands used to control and report modem operation in data modem mode are defined in this section. The Data Modem Mode commands and responses described in this section are applicable when command +FCLASS=0. (See +FCLASS for the definition of the FCLASS command.) The default values are typical of a fully configured modem supporting all data rates and options. The actual default value is dependent upon modem software as defined by the .
USRobotics Command Reference All of the functions of the command are completed before the modem issues the result code. The DTE should not include additional commands on the same command line after the Z command because such commands are ignored. Syntax Z Result Code OK +FCLASS - Select Active Service Class This command selects the active service class (mode). Syntax +FCLASS= Defined Values Decimal number which corresponds to the selected service class. 0 Select Data Mode (Default.

Syntax +GMR Typical Response +GMR: 1.
USRobotics Command Reference +GOI - Request Global Object Identification This command causes the modem to transmit one or more lines of information text identifying the device, based on the ISO system for registering unique object identifiers. Typically, the text consists of a single line containing numeric strings delimited by period characters. The general format of object identifiers is defined in Section 28 of ITU-T Recommendation X.208; the encoding rules are defined in ITU-T Recommendation X.209.
USRobotics Command Reference Syntax +GCI= Defined Values 8-bit country code from Annex A of T.35. The value is the hexadecimal equivalent of the T.35 code, with bit 8 treated as the most significant bit and bit 1 treated as the least significant bit. Default If the modem is specified for use in only one country, that country code is the default. Otherwise, the default is the expected country of sale or first installation.
USRobotics Command Reference Defined Values Decimal number corresponding to the selected option. 0 Disables command echo. 1 Enables command echo. (Default.) Result Codes OK = 0 or 1. ERROR Otherwise. Q - Quiet Results Codes Control The command enables or disables the sending of result codes to the DTE according to the parameter supplied. The parameter value, if valid, is written to S14 bit 2.
USRobotics Command Reference 1 Enables long-form (verbose) result codes. (Default.) Result Codes OK = 0 or 1. ERROR Otherwise. W - Connect Message Control This command, in conjunction with S95 bits 0, 2, 3, and 5 (bits 2, 3, and 5 can be written directly by the host or by the +MR, +ER, and +DR commands, respectively), control the format of CONNECT messages (see Table 3-15). The actual result code messages reported reflect the W command setting and the S95 bit settings.

USRobotics Command Reference transmits carrier in the modulation scheme specified by the parameter n. The modem then transmits HDLC flags for a minimum of 1 second. The modem continues to transmit the HDLC flags until it receives a character from the DTE. When characters are received from the DTE, the modem adds start and end flags, performs zero-bit insertion, generates FCS, and deletes character pairs before transmitting the characters to the remote fax machine.
USRobotics Command Reference returns to command mode. The modem concludes an error is detected if carrier is lost for any period of time during or before the reception of a frame. If carrier is lost for a time period longer than the time specified by the register S10, the modem finishes delivering the data in the receive buffer (if any) to the DTE, sends , generates the ERROR message, and returns to command mode. All subsequent data received from the remote is discarded.
USRobotics Command Reference generates the CONNECT message to the DTE and waits for further data from the DTE while transmitting NULLs to the remote. If more data is received before five seconds elapse, the modem continues to transmit the data as described in the previous paragraph. If five seconds elapse and no data is received from the DTE, the modem drops carrier, goes on-hook, and generates the ERROR result code. Fax Data Reception Fax data reception is initiated using the AT+FRM= command.
