Chaper 2 AT Commands Set AT commands are issued to DTE to control the modem's operation. AT commands can only be entered while the modem is in command mode. Except for the A/ command and the +++ escape command, all commands must be prefixed with the attention code AT. For instance, the “A” command (below) would be entered as: "ATA". With out the AT prefix, the command line cannot be executed.
2.1 Data Mode Command A/ Executes Last Command When modem receives this command, modem executes the last command string entered. Do not conclude it by pressing “Enter”. A Answer Command This command instructs the modem to go off-hook and answer an incoming call. Bn Communication Standard Setting This command determines ITU-T vs. Bell standard. B0 Selects ITU-T V.22 mode when the modem is at 1200 bits/s. B1 Selects Bell 212A when the modem is at 1200 bits/s (default).
Hn Hook Control This command instructs the modem to go on-hook to disconnect a call, or off-hook to make the phone line busy. H0 Modem goes on-hook (default). H1 Modem goes off-hook. Result Codes: OK: n = 0, 1 ERROR: Otherwise In Request Identification Information This command displays specific product information about the modem. I0 Returns product ID code. I1 Display Firmware version and checksum on the DTE. I2 Customer Used. I3 Returns fix ID information for application software identification.
Mn Monitor Speaker Mode This command turns the speaker on or off. M0 The speaker is off. M1* The speaker is on until the modem detects the carrier signal. M2 The speaker is always on when modem is off-hook. M3 The speaker is on until the carrier is detected, except while dialing.
Qn Result Code Control Result codes are informational messages sent from the modem and displayed on your monitor. Q0* Enables modem to send result codes to the DTE. Q1 Disables modem from sending result codes. Result Codes: OK n = 0, 1 ERROR Otherwise T Select Tone Dialing This command instructs the modem to send DTMF tones while dialing. Vn DCE Response Format This command controls whether result codes are displayed as words or their numeric equivalents. V0 Displays result codes as numeric.
saved by the last &W command. Z0 Reset modem and retrieve active configuration profit from stored profit 0. Z1 Reset modem and retrieve active configuration profit from stored profit 1. Result Codes: OK n = 0, 1 ERROR Otherwise &Cn Data Carrier Detect (DCD) Control Data carrier detect is a signal from the modem to your computer indicating that the carrier signal is being received from a remote modem. DCD normally turns off when the modem no longer detects the carrier signal.
This command determines guard tone frequency and is only used in V.22 and V.22bis mode. This option is not used in North America and is for international use only. &G0* Guard tone disabled. &G1 Sets guard tone to 550 Hz. &G2 Sets guard tone to 1800 Hz. Result Codes: OK n = 0, 1, 2 ERROR Otherwise &Kn Local Flow Control Selection &K0 Disable flow control. &K1 Reserved. &K2 Reserved. &K3 Enable RTS/CTS flow control. &K4 Enable XON/XOFF flow control. &K5 Enable Transparent XON/XOFF flow control.
&Sn Data Set Ready (DSR) Option This command selects DSR action. &S0* DSR always ON. &S1 DSR comes on when establishing a connection and goes off when the connection ends. Result Codes: OK n = 0, 1 ERROR Otherwise &Un Protocol Selection &U0 Select V.PCM &U1 Select V.34Bis/V.34 &U2 Select V.32Bis/V.22Bis &U3 Select Bell 103 300bps &U4 Select V21 300bps &U5 Select V23 &V View Active Configuration and Stored Profile This command is used to display the active profiles.
&Zn = x Store Telephone Number This command is used to store up to three dialing strings in the modem nonvolatile memory for later dialing. The format for the command is &Zn = stored number where n is the location 0? to which the number should be written. The dial string may contain up to 31 characters. The ATDS = n command dials using the string stored in location n.

The modem attempts to connect using MNP 2-4 error control procedures. If this fails, the modem will connect in Normal modem \ N4 V.42 with ODP & ADP phase detection. \ N5* V.42 with ODP & ADP phase detection, MNP, or buffer (default). The modem attempts to connect in V.42 error control mode. If this fails, the modem attempts to connect in MNP mode. If this fails, the modem connects in buffer mode and continues operation. This is also known as V.42/ MNP auto reliable mode. \N6 V.42 or disconnect.

2.3 S Registers Definitions S registers generally affect how the AT commands perform. Contents of the registers can be displayed or modified when the modem is in command mode. To display the value of an S register: TYPE: ATSn?, where n is the register number. PRESS: Enter To modify the value of an S register: TYPE: ATSn = r where n is the register number, and r is the new register value.
S4 Response Formatting Character (User Defined) This register determines the ASCII value used as the line feed character. The modem uses a line feed character in command mode when it responds to the computer. Range: 0-127, ASCII decimal Default: 10 (line feed) Units: ASCII S5 Command Line Editing Character (User Defined) This register sets the character recognized as a backspace and pertains to asynchronous only.
encounters a comma (,) in the dial command string. Range: 1-255 Default: 2 Units: seconds S9 Carrier Detect Response Time Register S9 sets the time the remote modem's carrier signal must be present for the local modem to recognize it. This feature ensures that your modem does not mistake a busy signal, ring, or voice for the carrier signal. The value of this register is in tenths of a second. The default value is 600 ms , although you can change it from 1 to 255.
