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 DL Re-dial last number DR Answer mode enabled; originate mode disabled following handshake initiation. DP Pulse dialing enabled DS=n Dial stored telephone number n D#, * Extended touch tone pads DT Tone dialing enabled/Pulse dialing disabled D/ Delays for 125ms before proceeding with dial string 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$ Displays a list of dial commands D; Modem returned to idle state after dialing. The semicolon can only be placed at the end of the dial command.
