3.8 AT COMMAND RESULT CODES
The modem responds to commands from the DTE and to activity on the line by signalling to the DTE in the form of result
codes. The result codes that the modem can send are described below.
Two forms of each result code are available: long-form, an English-like "verbose" response, and short-form, a data-like
numeric response (included in parentheses following the long-form). The long-form code is preceded and terminated by the
sequence < CR> < LF>. The short-form is terminated by < CR>, only with no preceding sequence.
If result messages are suppressed, nothing is returned to the DTE. The long-form results codes can be modified by the OEM
through the ConfigurACE Configuration Utility Program. (See ConfigurACE description.)
OK (0)
The OK code is returned by the modem to acknowledge execution of a command line.
CONNECT (1)
The modem will send this result code upon connecting when:
1. The line speed is 300 bps and the modem has been instructed to report the line speed to the DTE upon connecting, or
2. The DTE speed is 300 bps and the modem has been instructed to report the DTE speed to the DTE upon connecting, or
3. The range of result code responses is restricted by the X command such that no speed reporting is allowed.
RING (2)
The modem sends this result code when incoming ringing is detected on the line. What qualifies as a ring signal is
determined by country-dependent parameters, modifiable through ConfigurACE.
When cellular interface is selected, RING indicates that the cellular phone is receiving an incoming call.
NO CARRIER (3)
The modem sends this result code when attempting to establish a call if:
1. Ringback is detected and later ceases but no carrier is detected within the period of time determined by register S7, or
2. No ringback is detected within the period of time determined by register S7.
This result code is also used when the modem auto-disconnects due to loss of carrier.
Under X0, if busy tone detection is enforced, this result code is used as a response to the detection of busy or circuit busy.
Under X0, if dial tone detection is enforced or selected, this result code is used to indicate that dial tone has not been
detected.
ERROR (4)
The modem returns this result code if the command line contains a syntax error or it is unable to execute a command
contained in the command line. It is issued if a command does not exist or if the parameter supplied is outside the permitted
range.
Under X0, X1, X2, and X3, this result is used instead of DELAYED and BLACKLISTED.
CONNECT 1200 (5)
For X1, X2, X3, and X4, the modem sends this result code when:
1. The line speed is 1200 bps and the modem has been instructed to report the line speed to the DTE upon connecting, or
2. The DTE speed is 1200 bps and the modem has been instructed to report the DTE speed to the DTE upon connecting.
(Also, see the W command.)
NO DIALTONE (6)
For X2 and X4, the modem sends this result code if it has been instructed to wait for dial tone during dialing but none is
received.
When cellular phone interface is selected, NO DIALTONE indicates that cellular service is not currently available.
