NT7D16 Data Access card

The maximum number of characters is 43. This limit includes the AT prefix,
and the record Terminator character, but does not include the ASCII space
character.

Echo

Throughout the dialogue phase, the DAC echoes all user input. In RS-232-C
modes 0, 1, 2, and 3, no inbound call messages are presented to the
modem. Prompts are presented only if the modem user originates the
call. In modes 8, 9, 10, and 11, no prompts or characters echo under any
circumstances. The echo function can be turned off with a Hayes dialing
command.

All prompts and responses issued by the system are displayed to the user
unless 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) are
used, all attempts to enable the echo or display is ignored. Likewise, the
Hayes Reset command is also ignored.

Result codes and messages

Each input record generates a result code which is sent to the user. Only
one 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 words

Table 181 "Hayes dialing result codes and messages" (page 465)

shows the

codes for each reply in both formats, and explanations for the codes.

Note 1: Verbose commands are the default and appear in upper case
characters only. Numeric commands are sent by issuing the Numeric
Results code command (explained later in this document).

Note 2: All verbose codes and messages are preceded and terminated
by the user defined Terminator and New Line characters. The default, or
reset, characters are the ASCII Carriage Return, and ASCII Line Feed.
The Numeric codes are preceded and terminated by the Terminator
character only.

Note 3: The Suppress result command (explained later in this
document) disables the sending of these codes. If in RS-232-C DAC
Host modes, this command is ignored.
