464 NT7D16 Data Access cardThe maximum number of characters is 43. This limit includes the AT prefix,and the record Terminator character, but does not include the ASCII spacecharacter.EchoThroughout the dialogue phase, the DAC echoes all user input. In RS-232-Cmodes 0, 1, 2, and 3, no inbound call messages are presented to themodem. Prompts are presented only if the modem user originates thecall. In modes 8, 9, 10, and 11, no prompts or characters echo under anycircumstances. The echo function can be turned off with a Hayes dialingcommand.All prompts and responses issued by the system are displayed to the userunless the display command has been disabled. Like the Repeat command,this is explained later in this document.Note: If the RS-232-C DAC Host modes (1, 2, 3, 8, 9, 10, 11, or 12) areused, all attempts to enable the echo or display is ignored. Likewise, theHayes Reset command is also ignored.Result codes and messagesEach input record generates a result code which is sent to the user. Onlyone code is sent regardless of the number of commands in the record.The reply is in one of two formats:• Numeric replies contain a one- or two-number code• Verbose replies contain one or more wordsTable 181 "Hayes dialing result codes and messages" (page 465) shows thecodes for each reply in both formats, and explanations for the codes.Note 1: Verbose commands are the default and appear in upper casecharacters only. Numeric commands are sent by issuing the NumericResults code command (explained later in this document).Note 2: All verbose codes and messages are preceded and terminatedby the user defined Terminator and New Line characters. The default, orreset, characters are the ASCII Carriage Return, and ASCII Line Feed.The Numeric codes are preceded and terminated by the Terminatorcharacter only.Note 3: The Suppress result command (explained later in thisdocument) disables the sending of these codes. If in RS-232-C DACHost modes, this command is ignored.Nortel Communication Server 1000Circuit Card ReferenceNN43001-311 01.04 StandardRelease 5.0 23 May 2008Copyright © 2003-2008, Nortel Networks.
