Since it is not intended for all users, the specifications and manual for the multiplex mode will be available in a separate text file, and will only be available in the electronic format upon request. AT Command Descriptions An AT Command is a command in asynchronous data format issued by the computer to the TA through the asynchronous computer-modem interface. AT Commands control the TA's behavior and actions. To send an AT Command from a computer to the TA, you must be running communication software and the TA must be in the command state. Exceptions to this are A/, A>, and +++. These commands are not preceded by AT, or followed by any more characters: • A/ - re-executes the last command once. • A> - re-executes the last command once or repeats the last call up to 9 times until aborted by pressing down on any key on the keyboard or front panel or until a successful connection with a remote TA has been made. • +++ - is the escape sequence code that is entered in data state to return the TA to command state. The TA will accept AT commands only while it is in command state. The AT command prefix may be typed in either upper 'AT' or lower case 'at'. Do not use a combination of upper and lower cases in the prefix. The following tables list all of the AT commands supported by the TA128. An asterisk * following a command option or value indicates that it is a default setting when the TA is shipped. 113
