Proprietary AT Command Set 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. 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] Bn [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 Function DP Pulse dialing enabled DR Answer mode enabled; originate mode disabled following handshake initiation. DSn 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 quiet 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.
