A

Asynchronous data communications

A method of communicating data in which each “character” (a 7- or 8-bit data word) is sent or received separately at a selectable data transfer rate, and is framed by extra bits preceding and following the character. Various error-checking methods use the total bit-count to determine whether the character received at one end of the data path is the same as the one sent at the other end. Also called asynchronous mode, this method, as opposed to synchronous mode, does not use a clock signal to meter data. (Since the 8400B Plus Data Module operates only in asynchronous mode, synchronous mode is not defined in this glossary.) See also data options.

AT command set

A de facto industry-standard set of commands used for configuration and operation of DCE devices or modems. The AT (Attention) command set originated with Hayes Microcomputer Products, Inc. The Lucent Technologies 8400B Plus Data Module uses a subset of the full AT command set.

C

Command files

Files created for or by data communications software running on a PC that can be used to execute a sequence of commands to complete a task, such as performing an automatic login to a specific remote device. Also called script files.

Command line

A string of one or more valid and compatible AT commands typed on one line with any applicable arguments. Most command lines begin with the AT prefix and end with a carriage return (issued by pressing ENTER ).

Command mode

An operating mode in which the 8400B Plus Data Module looks at all characters coming from its associated terminal device and attempts to interpret them as commands. See also on-line mode.
