1.2.3 AT Response Syntax
The default mode response shown below, is in text mode. See the
command V for further details.
Possible formats for the result codes are:
Basic format result code, such as OK. The Basic result code also has
a numerical equivalent.
Extended format result code, prefixed with a plus sign (+) or an
asterisk (*):
AT+<command>: <parameter >
AT*<command>: <parameter>
where the <parameter> is the result code value, note that a single
space character separates the colon character from the <parameter>.
If several values are included in the result code, they are separated by
commas. It is also possible that a result code has no value. The
extended syntax result codes have no numerical equivalent. They are
always issued in alphabetical form.
Information text response may contain multiple lines separated by
<CR>. The TE detects the end of informational text responses by
looking for a final result code response, such as OK.
There are two types of result code responses as outlined below:
Final Result Code
A final result code indicates to the TE that execution of the command
is completed and another command may be issued.
If you type an implemented AT command, you should get the result
code OK.
If you type an AT command that is not implemented, or which had
the wrong parameter or syntax, you will get an error result code. It is
ERROR or, for example, +<command> ERROR followed by an
error code.
Final result codes are:
Value General meaning
OK Command executed, no errors
ERROR Invalid command or command line too long
NO DIALTONE No dialling possible, wrong mode
BUSY Remote station busy
NO ANSWER Connection completion time-out
NO CARRIER Link not established or disconnected
