Except for the A/ command and the +++ escape command, all commands
must be prefixed with the attention code AT. For instance, the A command
(below) would be entered as: "ATA>". Without the AT prefix, the
command line cannot be executed. Once entered, AT cannot be deleted with
the Backspace or Delete key.
More than one command can be placed on a single line and, if desired,
separated with spaces for readability. Once the carriage return (Enter) key is
pressed, the command line is executed. A line with no carriage return is
ignored.
The modem accepts either upper or lower case characters in the command
line and ignores any spaces within or between commands. Typing errors can
be corrected with the Backspace key.
