Proprietary AT Command Set AUTO-MODE DETECTION Type: Configuration Format: AT [cmds] Nn [cmds] Description: Selects various options for the automatic detection and negotiation of protocols during the handshake process if the modem is communicating with a remote modem of dissimilar speed. Command Function N0 Auto-mode detection disabled N1 In originate mode, handshake begins at line speed designated by the S37 register. Modem can shift to a slower speed if necessary. In answer mode, handshake attempted with the following protocols in order - V.FC, V.32bis, V.32, V.22bis, V.22 or Bell 212, V.21, and Bell 103 COMMUNICATIONS MODE Type: Configuration Format: AT [cmds] &Qn [cmds] Description: Selects communications mode options Command Mode &Q0 Asynchronous mode, serial port speed follows connect speed. &Q5 Asynchronous reliable mode DATA TERMINAL READY (DTR) Type: Configuration Format: AT [cmds] &Dn [cmds] Description: Selects modem response to DTR Note: The action each variant of &D causes depends on the setting of &Q Command Function &D0 Modem does not respond to DTR &D1 Modem goes to command mode after DTR goes is off &D2 Modem goes to command mode and disconnects (hangs up) after DTR goes off; Auto-Answer is disabled. &D3 Modem is initialized after DTR goes off FACTORY DEFAULT PROFILE Type: Configuration Format: AT [cmds] &F [cmds] Description: Sets values in active profile to values found in the default profile Command Function &F0 Direct mode without flow control &F2 Reliable mode FLOW CONTROL Type: Configuration Format: AT [cmds] &Kn [cmds] Description: Enables flow control options Command Function &K0 Flow control disabled &K3 RTS/CTS flow control enabled &K4 XON/XOFF flow control enabled &K5 Transparent XON/XOFF flow control enabled REPORT INFORMATION Type: Immediate Format: AT [cmds] In [cmds] Description: Displays information requested Command Function I0 Reports maximum data carrier rate I1 Reports ROM checksum I2 Tests and reports ROM checksum I3 Reports ROM code revision number I4 Report supported protocols in encrypted format I5 Reports firmware copyright information I7 Reports data pump model I10 Reports optional features I92 Reports product ID code SPEAKER VOLUME Type: Configuration Format: AT [cmds] Ln [cmds] Description: Controls speaker volume Command Function L0 Low volume setting L2 Medium volume setting L3 Highest volume setting Extended AT Commands AUTO-RETRAIN - AUTO-FALLBACK/FALL-FORWARD Type: Configuration Format: AT [cmds] %En [cmds] Description: Controls auto-retrain mode and fallback/fall-forward Command Function %E0 Auto-retrain disabled %E1 Auto-retrain enabled RATE NEGOTIATION Type: Configuration Format: AT [cmds] %Gn [cmds] Description: Controls rate negotiation Command Function %G0 Rate negotiation disabled %G1 Rate negotiation enabled S(status) -REGISTERS CONNECTION FAILURE CODES Type: Register Format AT [cmds] S86? [cmds] Description: Reports codes which correspond to the possible causes of a connection failure Value Meaning 0 Normal hang up 4 Carrier signal lost 5 No error-control detected for remote modem during feature negotiation 6 Remote modem failed to respond to feature negotiation 7 Local modem is asynchronous-only, remote modem is synchronous-only 8 No common framing technique found 9 No common protocol found 10 Remote modem sent erroneous feature negotiation message 11 Remote modem failed to send synchronous information 12 No failure - remote modem disconnected normally 13 Remote modem failed to respond after 10 re-transmissions same message 14 Violation of negotiated protocol caused failure DCE LINE SPEED Type: Register Format AT [cmds] S37=n [cmds] Description: Sets the maximum allowable data exchange rate attempted during handshake process. Command Function S37=0 Speed of last connection S37=1 300bps S37=5 1200bps S37=6 2400bps S37=8 4800bps S37=9 9600bps S37=10 12.0Kbps S37=11 14.4Kbps S37=12 7200bps ERROR CORRECTION NEGOTIATION Type: Register Format AT [cmds] S36=n [cmds] Description: Selects the action of the modem if it fails to connect with the error-correction protocol set in &Q. Command Function S36=0 Hang up S36=1 Attempt a direct connection S36=3 Attempt a buffered connection S36=4 Attempt a connection at MNP2-4; if that fails, hang up. S36=5 Attempt a connection at MNP2-4; if that fails, attempt a direct connection. S36=7 Attempt a connection at MNP2-4; if that fails, attempt a buffered connection. EXTENDED RESULT CODES Type: Register Format AT [cmds] S95=n [cmds] Default: 0 Range: 0-255 Unit: Bit-mapped Description: Works in combination with the Wn command to enable extended result codes. Features enabled by S95 take precedence over the options selected by Wn. Bit Value Function 1 0 Verbose CONNECT result codes display DTE or line speed only. 1 Adds "/ARQ" to all verbose CONNECT result codes except "NONE." 2 0 CARRIER result codes disabled. 1 CARRIER result codes enabled. 4 0 Enable CARRIER XXXX result code 8 0 Enable PROTOCOL XXXX result code 16 0 Reserved 32 0 Compression result code 64 0 Enable TX and RX V.34 CARRIER result code if in asymetric carrier mode 128 0 Reserved FEATURE NEGOTIATION OPTIONS Type: Register Format: AT [cmds] S48=n [cmds] Description: Selects active error correction and compression protocols Command Function S48=0 Detection negotiation disabled, XID negotiation disabled S48=7 Detection negotiation and XID negotiation enabled S48=128 Fall-back to options set in S36
