Use the O command to return to Data mode from

online Command mode. Enter the following command:

TYPE: ATO

PRESS: Enter

Command Guidelines

Review the following guidelines before using any AT Commands.

•The escape sequence (+++) is used to enter online Command mode from Data mode.

•The asynchronous character format for the AT command set must be one of the following:

—8 data bits + no parity + 1 stop bit.

—7 data bits + no parity + 2 stop bits.

—7 data bits + parity + 1 stop bit (parity can be odd, even, mark, or space).

•All commands (except A/ (repeat last command) and +++) must begin with the characters AT and end by pressing the Enter key. The AT (or at) prefix clears the command buffer and matches the modem speed and parity to that of the DTE. Commands can be upper- or lowercase, but the modem will not recognize mixed case prefixes (At or aT).

•Commands can be entered one at a time or in strings. Strings can have up to 40 characters after the AT prefix. You can use spaces, hyphens (–), and parentheses ( ) as fillers to make the commands easier to read; the modem ignores these fillers and they are not counted among the characters which make up the command string. Commands must be entered on one line and end with the carriage return character (Enter key).

•Commands with the suffix n have several options associated with them. For example, in the

Ln command, L1 sets the speaker volume to Low and L3 sets the speaker volume to High. If no value is entered for the n suffix, the modem assumes a zero (0) value.

•The A / command (without pressing the Enter key) causes the modem to repeat the last command entered.

•Valid commands are acknowledged with numeric or word result codes (unless the result codes have been disabled using the Q1 command). (See Appendix B for a list of result codes with numeric and word equivalents.)

AT Command List

AT commands are issued from an asynchronous DTE, such as a PC, and control the modem’s operation and software configuration. AT commands are only applicable when the DTE Dialer Type configuration option is set for AT. (See &Mn and &Qn commands.)

Table 14-1 lists all AT commands supported by the 3800 Series modem. The first column lists the AT command. The second column defines and lists all possible values for that command. The Async Dial factory default is listed in bold. The third column lists the key sequence used to enter the equivalent front panel command. Use this to reference commands in Chapters 5 through 12 if further description is necessary.
