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 When originating or answering; handshake only at DTE to modem rate N1 When originating or answering; handshake at DTE to modem rate. Modem can shift to a lower speed if necessary COMMUNICATION PROTOCOLS Type: Configuration Format: AT [cmds] Bn [cmds] Description: Selects the communication protocol for data calls Note: The B command allows the simultaneous selection of more than one suffix, enabling multiple protocols. Command Protocol B0 ITU-T V.22 at 300 or 1200bps B1 Bell 212A at 300 or 1200bps B2 V.23 at 75bps transmit, 1200bps receive in originate mode; 1200bps transmit, 75bps receive in answer mode CONFIGURATION PROFILES Type: Immediate Format: AT [cmds] &V [cmds] Description: Displays active and stored configuration profiles Command Function &V0 Display active profile &V1 Display stored profiles &V2 Display stored telephone numbers 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 is ignored (assumed on) &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 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 DW Dialing resumed following dial tone detection DP Pulse dialing enabled DR Answer mode enabled; originate mode disabled following handshake initiation. DS=n Dial stored telephone number n DT Tone dialing enabled/Pulse dialing disabled D, Dialing paused for amount of time specified in S8 register 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 silence up to the time specified in S7, is received prior to executing the rest of the dial string. 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 and XON/XOFF flow control enabled REPORT INFORMATION Type: Immediate Format: AT [cmds] In [cmds] Description: Displays information requested Command Function I0 Reports product code I1 Reports hardware variation code I2 Reports internal code I3 Reports software revision number I4 Reports product feature TEST MODES Type: Immediate Format: AT [cmds] &Tn Description: Selects test options Command Function &T0 End current test &T1 Begin local analog loopback test TRELLIS CODING Type: Configuration Format: AT [cmds] &Un Description: Enables/disables Trellis coding Command Function &U0 Trellis modulation enabled &U1 Trellis modulation disabled Extended AT Command Set 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 %E2 Auto-retrain, fallback/fall-forward enabled %E3 Auto-retrain, fast hang-up enabled CPU SOURCE LOADING Type: Configuration Format: AT [cmds] %N [cmds] Description: Sets dynamic CPU loading percentage Command Function %N0 Dynamic CPU loading disabled %N1 Dynamic CPU loading not to exceed 10% %N2 Dynamic CPU loading not to exceed 20% %N3 Dynamic CPU loading not to exceed 30% %N4 Dynamic CPU loading not to exceed 40% %N5 Dynamic CPU loading not to exceed 50% %N6 Dynamic CPU loading not to exceed 60% %N7 Dynamic CPU loading not to exceed 70% %N8 Dynamic CPU loading not to exceed 80% %N9 Dynamic CPU loading not to exceed 90% LINE SIGNAL QUALITY Type: Immediate Format: AT [cmds] %Q [cmds] Range: 0-255 Unit: Unidentified Description: Returns a value which indicates line signal quality S(status) -REGISTERS CONNECTION FAILURE CODES Type: Register Format AT [cmds] S86?
