The XE3314L operates in three modes; Command Mode, Fax Mode and Data Mode. Extensions to the AT command set support fax operation. Command Line - A command line may include multiple commands. The modem executes the commands in the sequence they appear in the command line. Spaces, inserted to improve legibility, do not fill space in the command buffer. A carriage return terminates the command line and causes the commands to be executed. Register S3 allows the user to select a character other than a carriage return to terminate the command line. Data Mode: The modem enters data mode after establishing a modem link and issues a "CONNECT" result code. In Data Mode the modem modulates all signals presented on Transmit Data, Pin 13, and sends them to the remote modem. The modem demodulates the signal from the remote modem and places it onto Received Data, Pin 3, for the host equipment. When the modem exits data mode, it issues a "NO CARRIER" result code. Command Buffer - The command buffer holds a maximum of 40 characters, including the AT prefix. If it overflows, the modem issues an "ERROR" result code and commands are not executed. Command Line Editing - A backspace can be used to edit the command line any time before it is executed. The backspace character erases the previous character in the command line. Any character except for the "A" and "T" can be erased. Register S5 allows the user to select a character other than a backspace to edit the command line. Command Mode: The XE3314L enters command mode on application of power, reset, loss of the connection, or receipt of the escape sequence. In command mode the modem accepts commands from the host on Transmit Data. Appropriate result codes are returned on Received Data at the same speed and parity as the commands. Re-Execute Last Command - The A/ command causes the XE3314L to re-execute the command line stored in the command buffer. This is the only command which does not require the "AT" prefix. Fax Mode: The modem enters fax mode on receipt of the AT+FCLASS=1 command. Fax commands and responses are issued at 19,200 bits per second; the character format is 8 bits no parity. The modem accepts Class 1 Fax commands only in fax mode. The A/, ATO, AT&T and escape commands are not valid in fax mode. Omitted Parameters - Most commands include a parameter which determines the command function. When the parameter is omitted from the command string, it is assumed to be a 0. Commands The modem is configured and controlled with AT commands. AT commands follow a strict format. The command line is stored in the command buffer and executed upon receipt of a carriage return. Until executed, the command line can be edited with the backspace key. Escape Characters - A three character escape sequence, entered while in data mode, will switch the modem into command mode while remaining on line. The escape character, set by Register S2, is entered 3 times in succession to execute the escape. The default escape sequence is "+++." Command Format - Each command, except A/, begins with the AT prefix. The "A" and "T" may be both upper case or both lower case but cannot be of different cases. The modem uses the prefix to identify the host's speed and parity. The modem determines speed by measuring the width of the incoming bits and parity by comparing the parity bits of the "A" and "T." The modem then returns result codes at the host's speed and parity. XECOM Result Codes - The modem issues a result code after each action. Result codes may be provided as full words, numeric codes or may be disabled. Each result code ends with a carriage return when numeric result codes are chosen. When full word result codes are chosen, a Line Feed and Carriage Return precede and follow each (6) XE3314L XE3314L AT COMMANDS (continued) Mn - Speaker Activity - ATMn determines when the List of Commands An asterisk indicates the default setting of the command for the modem's audio output is active. n=0 Speaker off XE3314L. n=1 Speaker on until carrier received* n=2 Speaker remains on A - Answer Command - ATA forces the modem to n=3 Speaker off during dialing, on until carrier immediately go off-hook and begin transmitting the answer tone sequence.
