PROPRIETARY AT COMMAND SET AUTO-MODE DETECTION Type: Configuration Format: AT [cmds] N n [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. Handshake begins at line speed designated by the S37 register. If S37=0 handshake follows interface speed N1 Auto-mode detection enabled. Handshake begins at line speed designated by the S37 register. If S37=0 handshake at highest possible speed with fallback to lower speed if necessary COMMUNICATION PROTOCOLS Type: Configuration Format: AT [cmds] B n [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 B1 Bell 212A at 1200bps B2 ITU-T V.23 at 75/1200bps in originate mode, 1200/75bps 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 profile &V2 Display stored telephone numbers DATA SET READY (DSR) Type: Configuration Format: AT [cmds] &S n [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] &D n [cmds] Description: Selects modem response to DTR Command Function » &D0 Modem does not respond to DTR &D1 Modem goes to command mode on DTR toggle &D2 Modem goes to command mode and disconnects (hangs up) on DTR toggle; Auto-Answer is disabled on low DTR. &D3 Modem is initialized on DTR toggle 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 DS=n Dial stored telephone number n 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.
