most commands, when you are entering them using a terminal connection, you will need to
preface the command with AT (exceptions are noted), i.e. ATA which listed as A
• Some commands have specific parameters while other commands will take whatever you type.
• Acceptable parameters and/or specific formats are in the parameters column.
• Required variable parameters are denoted with italicized text, example, Dn. The n is variable
and noted in the parameters column.
• Optional parameters are denoted with square brackets [ ].
• Most commands with parameters can be entered with ? to read the current value (for example,
AT&D? will respond with “2” if the default has not been changed).
• AT Commands are not case sensitive. A capital “E” is the same as a lower-case “e”.
• When you are using a terminal connection, if you enter a command which is recognized by the
Raven X, it will respond with “OK”. If the command is not recognized, the response will be
“ERROR”.
• Those commands applicable only to certain model numbers of the Raven X will be noted.
Caution: Symbols listed with commands, such as /, &, or ?, are part of the com-
mand and must be included.
