Proprietary AT Command Set DISPLAY BLACKLIST NUMBERS Type: Immediate Format: AT [cmds] *N [cmds] Description: Displays the list of all the numbers on the blacklist (whether they are delayed/forbidden or not), and their statuses. DISPLAY DELAYED NUMBERS Type: Immediate Format: AT [cmds] *D [cmds] Description: Displays the list of all delayed numbers and their statuses. DISPLAY FORBIDDEN NUMBERS Type: Immediate Format: AT [cmds] *F [cmds] Description: Displays the list of all forbidden numbers and their statuses. CONNECT SPEED MATCHING Type: Configuration Format: AT [cmds] %Ln [cmds] Description: Selects whether the modem will attempt to match the connect speed of the remote modem. Command Function %L0 Modem will connect at speeds supported by the protocol selected only. %L1 Modem will match connect speeds. %L2 Modem will connect only at current speed. %L3 Modem will use V.8 automode with fallback to ITU-T automode to match speeds. %L4 Modem will use V.8 automode to match speeds. V.34 TRAINING RESPONSE Type: Register Format: AT [cmds] :T42=n [cmds] Description: Sets what speed the modem will choose after a V.34 train. Command Function :T42=0 Standard speed selection. :T42=1 Choose speed approximately 2 speeds faster than standard. :T42=2 Choose speed approximately 1 speed faster than standard. :T42=3 Standard speed selection. :T42=4 Choose speed approximately 1 speed slower than standard. :T42=5 Choose speed approximately 2 speeds slower than standard.
