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 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 Modem 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 Load factory configuration 0 &F1 Load factory configuration 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 Unidirectional 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 Command Function &G0 Guard tone disabled &G2 1800Hz guard tone enabled MODULATION FORMAT Type: Configuration Format: AT [cmds] Fn [cmds] Description: Selects modulation format Command Function F0 Autoscan F1 300bps (V.21 or Bell 103) F3 1200/75bps (V.23) F4 1200bps (V.22 or Bell 212A) F5 2400bps (V.22bis) F6 4800bps (V.32 or V.32bis) F7 7200bps (V.32bis) F8 9600bps (V.32 or V.32bis) F9 12.0Kbps (V.32bis) F10 14.4Kbps (V.32bis) REPORT INFORMATION Type: Immediate Format: AT [cmds] In [cmds] Description: Displays information requested Command Function I0 Reports product name 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 synchronous mode, CTS tracks the state of RTS; CTS/RTS delay is defined by S26. In asynchronous mode, CTS acts according to V.25bis handshake &R1 In synchronous mode, CTS is forced high. In asynchronous mode, CTS will drop if required by flow control EXTENDED AT COMMAND SET DSR WINK Type: Immediate Format: AT [cmds] %Sn [cmds] Description: Sets Data Set Ready wink options Command Function %S0 DSR wink disabled %S1 DSR wink enabled. When DTR is forced high (&S0) and the modem goes on-hook, an off period of 1 second is forced LINE SIGNAL QUALITY Type: Immediate Format: AT [cmds] %Q [cmds] Range: 000-127 Unit: Unidentified Description: Returns a value which indicates line signal quality V.23 MODE Type: Configuration Format: AT [cmds] %Fn [cmds] Description: Selects V.23 split-speed and half-duplex Command Function %F0 V.23 mode disabled %F1 75bps transmit, 1200bps receive (split-speed) %F2 1200bps transmit, 75bps receive (split-speed) SPECIAL COMMANDS MNP10 - POWER LEVEL ADJUST Type: Configuration Format: AT [cmds] -SEC=n [cmds] Range: 0-30 Unit: -1dBm Description: Controls automatic transmit power level adjustment during MNP 10 link negotiation Command Function -SEC=0 MNP10 disabled.
