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 Auto-mode detection enabled 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 &Q6 Buffered asynchronous mode DATA SET READY (DSR) Type: Configuration Format: AT [cmds] &Sn [cmds] Description: Selects DSR options Command Function &S0 DSR forced high &S1 DSR high only while modem is handshaking or connected DATA TERMINAL READY (DTR) Type: Configuration Format: AT [cmds] &Dn [cmds] Description: Selects modem response to DTR Command Function &D0 DTR override &D1 DTR toggle causes online command mode &D2 Normal DTR operations &D3 Resets on receipt of DTR DIAL Type: Immediate Format: AT [cmds] D<#> [cmds] Description: Dials telephone number according to any modifiers included in the string Note: Any combination of modifiers can be used to produce the desired dial functions in sequence. Command Function DL Re-dial last number DP Pulse dialing enabled DS=n Dial stored telephone number n DT Tone dialing enabled DW Dialing resumed following dial tone detection D, Dialing paused D! Flash function initiated. Modem commanded to go off-hook for specified time before returning on-hook. D@ Wait for Quite Answer function enabled. Modem waits until a "quiet answer," a ring-back signal followed by 5 seconds of silence D; Modem returned to idle state after dialing. The semicolon can only be placed at the end of the dial command. D^ Toggle calling tone 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 Factory default profile 0 &F1 Factory default profile 1 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 &K6 RTS/CTS & XON/XOFF flow control enabled GUARD TONE Type: Configuration Format: AT [cmds] &Gn [cmds] Description: Commands the modem to transmit a guard tone in V.22/V.22bis Note: Used primarily for international data transmission Command Function &G0 Guard tone disabled &G2 1800Hz guard tone enabled LINE MODULATION Type: Configuration Format: AT [cmds] Fn [cmds] Description: For compatibility only; non-functional. Use +MS to select line modulation REPORT INFORMATION Type: Immediate Format: AT [cmds] In [cmds] Description: Displays information requested Command Function I0 Reports maximum line speed I1 Reports product type I2 Reports checksum firmware I3 Reports product name I4 Reports firmware release I5 Reports active Country Code RTS/CTS Type: Configuration Format: AT [cmds] &Rn [cmds] Description: Selects RTS/CTS options Command Function &R0 In asynchronous mode, C106 is controlled according to V.25 handshake recommendation &R1 In synchronous mode, C106 follows flow control SPEAKER VOLUME Type: Configuration Format: AT [cmds] Ln [cmds] Description: Controls speaker volume Command Function L1 Low volume setting L2 Medium volume setting L3 Highest volume setting S(status) REGISTERS TRANSMISSION LEVEL - FAX Type: Register Format: AT [cmds] S92=n [cmds] Range: 3-15 Unit: -1 dBm Description: Sets the signal level for transmission while in fax mode TRANSMISSION LEVEL - LEASED-LINE Type Register or Configuration Format AT [cmds] S91=n [cmds] Range 3-15 Unit -1 dBm Description Sets the signal level for transmission over leased-lines 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.
