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 Error correction mode DATA TERMINAL READY (DTR) Type: Configuration Format: AT [cmds] &Dn [cmds] Description: Selects modem response to DTR 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, no flow control &F2 Reliable mode, flow control enabled 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 product code ID I1 Reports ROM checksum I2 Tests and reports ROM checksum I3 Reports ROM code revision number I4 Reports supported protocols in encrypted format I5 Reports firmware copyright information I7 Reports data pump model I10 Reports optional features supported by the modem 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 CONNECT MODE Type: Configuration Format: AT [cmds] \Nn [cmds] Description: Controls the type of connection the modem will operate in Command Function \N0 Normal mode enabled \N1 Direct mode enabled \N2 Reliable mode enabled \N3 Auto-reliable mode enabled \N4 V.42 reliable mode enabled REQUEST A RETRAIN Type: Configuration Format: AT [cmds] %En [cmds] Description: Controls the retrain request Command Function %E0 Do not request a retrain %E1 Request a retrain 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 9 No common protocol found 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 12000bps S37=11 14400bps S37=12 7200bps ERROR CORRECTION/COMPRESSION Type: Register Format: AT [cmds] S46=n [cmds] Default: 136, 138 Range: 138 Description: Selects active error correction and compression protocols Command Function S46=136 Active error correction and compression protocols disabled S46=138 Active error correction and compression protocols enabled EXTENDED RESULT CODES Type: Register Format AT [cmds] S95=n [cmds] 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 0 0 CONNECT result code reports DTE speed. 1 CONNECT result code reports line speed instead DTE speed. 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. 3 - 4 0 Reserved 5 0 COMPRESSION result codes disabled. 1 COMPRESSION result codes enabled. 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
