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 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^ Disable calling tones DJ Perform an MNP10 connection DK Enable power level adjustment during MNP10 connection D; Modem returned to idle state after dialing. The semicolon can only be placed at the end of the dial command.
