Commands for Host-Processed Modems Reference Manual 2 Syntax and Procedures The command and response syntax and procedures generally conform to referenced recommendations and standards.
Commands for Host-Processed Modems Reference Manual 2.2.2 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. Any control characters (IA5 0/0 through 1/15, inclusive) that remain in the command line after receipt of the termination character are ignored by the modem.
Commands for Host-Processed Modems Reference Manual 2.3 Basic Syntax Commands 2.3.1 Basic Syntax Command Format The format of Basic Syntax commands, except for the D and S commands, is as follows: [] where is either a single character, or the "&" character followed by a single character per V.250. In addition, can be the "%" character followed by a single character, the "*" character followed by a single character, or the "^" character followed by a single character.
Commands for Host-Processed Modems 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) .
Commands for Host-Processed Modems Reference Manual String Constants String constants consist of a sequence of displayable IA5 characters, each in the range from 2/0 to 7/15, inclusive, except for the characters ‘"’ (IA5 2/2) and "\" (IA5 5/12). String constants are bounded at the beginning and end by the double-quote character (‘"’, IA5 2/2). Any character value may be included in the string by representing it as a backslash ("\") character followed by two hexadecimal digits.
Commands for Host-Processed Modems Reference Manual If all other relevant criteria are met (e.g., the modem is in the proper state), the command is executed with any indicated subparameters. If is not recognized, the modem issues the ERROR result code and terminates processing of the command line.
Commands for Host-Processed Modems Reference Manual is not recognized, one or more mandatory values are omitted, or one or more values are of the wrong type or outside the permitted range, the modem issues the ERROR result code and terminates processing of the command line. An ERROR is also generated if too many values are specified. In case of an error, all previous values of the parameter are unaffected.
Commands for Host-Processed Modems 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.
Commands for Host-Processed Modems Reference Manual 2.6.2 Handling of Invalid Numbers and S-Parameter Values The modem reacts to undefined numbers and S-parameter values in one of three ways: 1. Issue the ERROR result code, and leave the previous value of the parameter unchanged; 2. Issue the OK result code, and leave the previous value of the parameter unchanged; or, 3. Issue the OK result code, and set the parameter value to the valid value nearest to that specified in the command line.
Commands for Host-Processed Modems Reference Manual Result Code Types. There are three types of result codes: final, intermediate, and unsolicited. Result codes are described in Section 3.4. 2.7.2 1. A final result code indicates the completion of a full modem action and an ability to accept new commands from the DTE. 2. An intermediate result code is a report of the progress of an modem action. The CONNECT result code is an intermediate result code.
Commands for Host-Processed Modems Reference Manual Fax Modes. If a single value is to be reported, the form of the result code is: or () 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.
