Bit Value Function 0 0 Not used 1 0 Binary synchronous protocol used. 1 HDLC protocol used. 2 0 HDLC address detect disabled. 1 HDLC address detect enabled. 3 0 NRZI bit coding used. 1 NRZ bit coding used. 4 0 HDLC idle sends MARK. 1 HDLC idle sends FLAG or SYNC. AUTOSYNC HDLC ADDRESS Type: Register Format: AT [cmds] S20=n [cmds] Default: 0 Range: 0-255 Unit: Unidentified Description: Sets the HDLC address and binary synchronous character. BREAK TYPE Type: Configuration Format: AT [cmds] \Kn [cmds] Description: Configures action of break signal. Command Function \K0 Online command mode enabled, break not sent to remote modem. \K1 Break sent to remote modem and buffers cleared. \K3 Break sent to remote modem immediately. \K5 Break sent with transmitted data. DIAL Type: Immediate Format: AT [cmds] D<#>;[cmds] Description: Dials the telephone number indicated 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. 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. 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^ Enable calling tone for this call. D; Modem returned to idle state after dialing. The semicolon can only be placed at the end of the dial command.
