Result Code Commands
The following commands control Result Codes.

ATQ Enables Result Codes (default).
ATQ1 Disables Result Codes.
ATV Displays Result Codes as numbers.
ATV1 Displays Result Codes as words (default).
ATW Upon connection, the modem reports only the DTE speed (e.g., CONNECT 19200). Subsequent responses are disabled. (Default.)
ATW1 Upon connection, the modem reports the line speed, the error correction protocol, and the DTE speed, respectively. Subsequent responses are disabled.
ATW2 Upon connection, the modem reports the DCE speed (e.g., CONNECT 14400). Subsequent responses are disabled.
ATS95 Extended Result Codes
The bits in this register can be set to override some of the Wn command options. A bit set to a 1 in this register will enable the corresonding result code regardless of the Wn setting. Default: Ø

Bit Ø - CONNECT result code indicates DCE speed instead of DTE Speed.
Bit 1 - Append/ARQ to CONNECT XXXX result code in error-correction mode. (XXXX=rate.)
Bit 2 - Enable CARRIER XXXX result code. (XXXX=rate.)
Bit 3 - Enable PROTOCOL XXXX result code. (XXXX=protocol identifier.)
Bit 4 - Reserved.
Bit 5 - Enable COMPRESSION result code (XXXX=compression type.)
Bit 6 - Reserved.
Bit 7 - Reserved.

Sample Result Codes
The following Result Codes are returned when your computer rate is set to 38,400 bps in your telecommunications software; your modem connects to a 9600 bps modem that supports V.42; and Result Codes are enabled (ATQØ); set to be returned as words (ATV1); and set to report throughput, error correction, and connection rate (ATW1).

CARRIER 9600
PROTOCOL: LAPM
CONNECT 38400

These Result Codes indicate a 9600 bps connection rate, LAPM (V.42) error correction, and 38,400 bps maximum throughput.

Using the same example, ATWØ would return only CONNECT 38400 (computer rate) and ATW2 would return only CONNECT 9600 (connection rate).

Determining Which Result Codes To Use
The Result Code commands you need depend on your software. The factory default settings ensure compatibility with most software. If you have all of the codes turned on, but your software expects only the CONNECT XXXX Result Code, it cannot use extra information provided by a command such as W1.

List of AT Command Result Codes
The following Result Codes are available on your modem.
