Proprietary AT Command Set 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 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^ Disable calling tone transmission for this call only 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 Auto-mode detection disabled N1 Auto-mode detection enabled 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 escape mode after DTR goes is off &D2 Modem goes to command mode and disconnects (hangs up) after DTR goes off; Auto-Answer is disabled.
