AT Command Descriptions

The AT command is a command in asynchronous data format issued by the computer to the Model XM128 modem through the asynchronous computer-modem interface. AT commands control the behavior and actions of the modem.

To send an AT command from a computer to the Model XM128 modem, the following rules apply:

•You must be running a communication software.

•The modem must be in the command state.

The commands A/, A>, and +++ are exceptions. These commands are not preceded by AT or followed by any more characters.

•The AT command prefix can be typed in either uppercase letters (AT) or lowercase letters (at). Do not combine uppercase and lowercase letters in the prefix.

Table C-1, Table C-2, Table C-3, and Table C-4 list the AT commands supported by the Model XM128 modem. An asterisk (*) following a command option or value indicates that it is a default setting when the Model XM128 modem is shipped. Table C-1 lists the basic AT command set.
