At Command Result Codes - Eicon Technology DIVA T/A ISDN Modem Reference Manual

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.
