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. |
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
