Command Function DL Re-dial last number 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.
