All of these parameters may be changed on the local terminal device as needed. The 8400B Plus Data Module will adjust to match the speed and parity of the local terminal device when it receives an AT command.

If you connect to a remote system and your screen shows a series of nonsense characters (also referred to as “garbage”), chances are that you need to adjust the speed or parity on the terminal to match the settings of the 8400B Plus Data Module, which has adjusted its speed to match the remote system.

Command Buffer

As you type in a command, each character is saved in a 40-character buffer. The AT prefix, spaces, and the ENTER at the end of the command line are not saved and do not add to the character count. If you try to type more than 40 countable characters on one line, the result code ERROR will be displayed on your terminal screen, and the command line will be ignored.

Command Line Set Up

A command line begins with the AT prefix, includes one or more commands, and finishes with a line termination character, usually issued by pressing the ENTER key. The factory-default line termination character is an ASCII carriage return.

If you make an error while typing a command line, you can send the backspace character, usually issued by pressing the BACKSPACE key, as often as needed to delete the error. However, as soon as you enter the AT prefix, the 8400B Plus Data Module immediately reads it and sets up for a command to follow. Hence,
