Proprietary AT Command Set 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 1200bps or ITU-T V.21 at 300bps B1 Bell 212A at 1200bps or Bell 103 at 300bps B2 V.23 selection, in originate mode and receive at 1200bps, transmit at 75bps; in answer mode, receive at 75bps and transmit at 1200bps. B3 V.23 selection, in originate mode receive at 75bps and transmit at 1200bps; in answer mode, receive at 1200bps and transmit at 75bps 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 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 DW Dialing resumed following dial tone detection 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. D; Modem returned to idle state after dialing. The semicolon can only be placed at the end of the dial command. 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 Handshake only at the communication rate specified by S37 with fallback disabled N1 Start handshake at the communication standard specified by S37. Fallback enabled V.32 - AUTO-RETRAIN Type: Configuration Format: AT [cmds] &Bn [cmds] Description: Controls auto-retrain function if poor line quality is detected Command Function &B0 Auto-retrain disabled modem hangs-up &B1 Auto-retrain enabled if line quality is poor &B2 Tolerate any condition 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 FLOW CONTROL Type: Configuration Format: AT [cmds] &Kn [cmds] Description: Enables flow control options Command Function &K0 Flow control disabled &K1 Reserved &K2 Reserved &K3 RTS/CTS flow control enabled &K4 XON/XOFF flow control enabled &K5 Error COMMUNICATIONS MODE Type: Configuration Format: AT [cmds] &Mn [cmds] Description: Selects communications mode Command Mode &M0 Asynchronous mode &M1 Synchronous connect mode and asynchronous off-line command mode. &M2 Synchronous connect mode and asynchronous off-line command mode and set DTR high. &M3 Synchronous connect mode &M4 Hayes AutoSync mode PULSE DIALING RATIO Type: Configuration Format: AT [cmds] &Pn [cmds] Description: Selects pulse dial make/break ratio Command Function &P0 39/61ms at 10pps (North America) &P1 33/67ms at 10pps (Europe) 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 CONFIGURATION PROFILES Type: Immediate Format: AT [cmds] &V [cmds] Description: Displays active and stored configuration profiles Command Function &V0 View active profile 0 &V1 View active profile 1 Extended AT Commands DATA COMPRESSION Type: Configuration Format: AT [cmds] %Cn [cmds] Description: This command controls the MNP5.
