AT Command Result Codes
This section provides the result codes, also known as status messages, that are displayed
after an AT command is issued.
Result codes can be displayed as a word message (long-form English) or as a number code
(short-form numeric response). Word messages are preceded and terminated by the
sequence <CR> <LF>. Numeric codes are terminated by <CR> only. The Result Code Format
command (ATVn) determines short- or long-form usage.
General Purpose Codes
Some number codes can be associated with more than one text string, depending on the
format selected by ATXn.
AT Result Codes - Connection Indicators
The following codes give you information about your connection. The word “CONNECT” in a
message can relate to either DCE speed or DTE speed, depending on the selection made with
ATXn. The word “CARRIER” always relates to DCE speed.
