GM47/GM48 INTEGRATOR’S MANUAL

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
