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.

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 .INF file.

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.
