Chapter Introduction
CHAPTER INTRODUCTION
Overview
This manual describes host commands responses RJModem. fundamental interface command syntax described Chapter Important Note: Available commands dependent upon country code selected; i.e., some commands available certain countries.
Syntax
command response syntax procedures generally conform referenced recommendations standards. Since these recommendations standards describe characteristics universal large installed base modems maximum degree, there syntax procedural differences extensions behavioral differences implemented commands, parameters, responses beyond those described these recommendations standards. syntax procedures described this section based V.250 V.253 with additional information included implemented extensions, behavioral differences beyond V.250, legacy commands.
Command Line Echo
modem echo characters received from during command state online command state back DTE, depending setting command. enabled, characters received from echoed same format received. Invalid characters command line incomplete improperly-formed command line prefixes echoed.
Repeating Command Line
prefix "A/" "a/" received, modem immediately executes once again body preceding command line. editing possible, termination character necessary. command line repeated multiple times this manner. Responses repeated command line issued using format original command line. "A/" received before command line been executed, preceding command line assumed have been empty (that results result code).
Types Commands
There types commands: action commands parameter commands. Commands either type included command lines, order. Action commands "executed" invoke particular function equipment, which generally involves more than simple storage value later use), "tested" determine whether equipment implements action command, and, subparameters associated with action, ranges subparameter values that supported). Parameters "set" store value values later use), "read" determine current value values stored), "tested" determine whether equipment implements parameter, ranges values supported).

Chapter Introduction
Executing Commands
Upon receipt termination character, modem commences execution commands command line order received from DTE. Should execution command result error character recognized valid command, execution terminated, remainder command line ignored, ERROR result code issued. Otherwise, commands execute correctly, only result code associated with last command issued; result codes preceding commands suppressed. commands appear command line, result code issued.
Aborting Commands
Some action commands that require time execute aborted while progress; these explicitly noted description command. Aborting commands accomplished transmission from modem character. single character sufficient abort command progress; however, characters transmitted during first milliseconds after transmission termination character ignored allow append additional control characters such line feed after command line termination character).
Modem Responses
There types responses modem issue: information text result codes. Information Text Information text usually consists single line; information text returned response some commands contain multiple lines. Result Code Types There three types result codes: final, intermediate, unsolicited. final result code indicates completion full modem action ability accept commands from DTE. intermediate result code report progress modem action. CONNECT result code intermediate result code. case dialing answering command, modem switches from command state online data state, issues CONNECT result code. This intermediate result code modem because cannot accept commands from while online data state. When modem switches back command state then issues final result code (such CARRIER). Unsolicited result codes (such RING) indicate occurrence event directly associated with issuance command from DTE. Extended Syntax Result Codes Extended syntax result codes issued response either basic extended commands, both. appropriate responses specified definitions commands, responses, both. Extended syntax result codes subject suppression command, with basic format result codes. issuance extended syntax result codes affected setting command. Extended syntax result codes final, intermediate, unsolicited. type indicated definition result code. Extended syntax result codes include reporting values. definition result code specifies whether values appended result code, and, many, their types, their assumed default values omitted.

CHAPTER DATA COMMAND
Command Guidelines
commands used control report modem operation data modem mode defined this section. Data Modem Mode commands responses described this section applicable when command +FCLASS equals default values typical fully configured modem supporting data rates options. actual default value dependent upon installed modem firmware country specific parameters. Commands accepted modem once previous command been fully executed, which normally indicated return appropriate result code. Execution commands either result direct command re-execute command, will aborted another character entered before completion handshake.
Escape Code Sequence
When modem established connection entered on-line data mode, possible break into data transmission order issue further commands modem on-line command mode. This achieved sending modem sequence three ASCII characters specified register default character '+'. Therefore, default escape code +++. maximum time allowed between receipt last character three escape character sequence from sending result code controlled register.

Read/Write S-Parameter
modem selects S-Parameter, performs S-Parameter read write function, and/or reports value S-Parameter. Establishes S-Parameter last register accessed. Sets S-Parameter value Reports value S-Parameter parameter omitted, which case last S-Parameter accessed will assumed. omitted AT?, which case last S-Parameter accessed will assumed. example: ATS7 Establishes last accessed register. AT=40 Sets contents last register accessed ATS=20 Sets contents last register accessed number outside range S-Parameters available, modem will return ERROR message. value outside range permitted given S-Parameter, modem will return ERROR message. Input output always decimal format. Note that some S-Parameters read-only. some cases, writing S-Parameter will appear accepted value will actually written. country restrictions, some commands will accepted, value limited replaced maximum minimum value.
