Result Codes
The modem responds to commands from the DTE and to activity on the line by signaling
to the DTE in the form of result codes. The result codes that the modem can send are
described in Table A-16.
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 . The short-form is terminated by , 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 .INF file.
Table A-6. Result Code Definitions
Code Message Meaning
+F4 +FCERROR
High speed fax data (V.27, V.29, V.33, or V.17) is expected but a V.21 signal is
received.
0 OK A command line has been executed.
1 CONNECT
For X command values specifying no speed reporting, the modem has connected to
the line and either the line speed is 300 bps and line speed is enabled, or the DTE
speed is 300 bps and DTE speed reporting is enabled.
2 RING
An incoming ring signal 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 receiving an incoming call.
3 NO CARRIER
Sent 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.
Also sent when the modem auto-disconnects due to loss of carrier.
For X0, sent for the following conditions:
1. If busy tone detection is enforced, busy or circuit busy has been detected
2. If dial tone detection is enforced or selected, dial tone has not been detected.
4 ERROR
Sent during an attempt to execute a command line if any of the following conditions
occur:
1. The command line contains a syntax error.
2. The modem cannot execute a command contained in the command line, i.e.,
the command does not exist or is not supported.
3. A command parameter within the command line is outside the permitted range.
For X0, X1, X2, and X3, this message is sent instead of DELAYED and
BLACKLISTED.
5 CONNECT 1200
The modem has connected to the line and either the line speed is 1200 bps and DCE
speed reporting is enabled, or the DTE speed is 1200 bps and DTE speed reporting is
enabled.
6 NO DIAL TONE
For X2 and X4, the modem has been instructed to wait for dial tone during dialing but
none is received. When cellular phone interface is selected, indicates that cellular
service is not currently available.
7 BUSY
For X3 and X4, if busy tone detection is enforced, the busy (engaged) signal is
detected on the line when the modem is attempting to originate a call.
8 NO ANSWER
The modem is attempting to originate a call if a continuous ringback signal is detected
on the line until the expiration of the timer S7.
9 CONNECT 600
The modem has connected to the line the DTE speed is 600 bps and DTE speed
reporting is enabled,
10 CONNECT 2400
The modem has connected to the line and either the line speed is 2400 bps and DCE
speed reporting is enabled, or the DTE speed is 2400 bps and DTE speed reporting is
enabled.
11 CONNECT 4800
The modem has connected to the line and either the line speed is 4800 bps and DCE
speed reporting is enabled, or the DTE speed is 4800 bps and DTE speed reporting is
