Hayes dialing

467

Command

Description

ATEn

Echo (n = 0, 1; if n = 1, commands echo back to terminal)

ATTSP!

Transparent mode

Note 1: To use AT dialing, enter CTRL-z at carriage return () when the port is idle.

Note 2: Follow each command (except A/) by a carriage return () to execute it.

For the purposes of this document, when illustrating the prompt/response
sequences, the bold type is what the user enters on the keyboard. All
other type represents the DAC output. Likewise, "xxxxxxx," "yyyyyyy,"
or "zzzzzzz" represents numbers entered by the user, or dialed by the
DAC, and in no way indicates the absolute character limit. The number of
characters is dependent on the feature activated (Auto Dial, Speed Call, for
example). Also, for simplicity purposes, all Result messages are shown in
Verbose code. See

Table 181 "Hayes dialing result codes and messages"

(page 465)

for a complete list of the Verbose and Numeric codes. See

Features and Services (NN43001-106-B) for a complete description of the
features operating.

S registers

These commands allow the user to access various dialing parameters. The
user can determine the present parameter setting, and alter the parameter.
These parameters are grouped into a set referred to as the S registers.

All S registers may be changed with the exception of S1, the Ring count.
If an attempt is made to change this parameter, the command is accepted
but no action is taken. The Ring count is the number of expired 6-second
intervals since an inbound call has been received. The current count may
be displayed through the Display S register command but cannot be altered
After a call is dropped, the Ring counter is set back to 0.

If, when using the display or alter commands, no register or value number is
input, the number 0 is used. For example, ATS? is equivalent to ATS0.

Allowable S registers

Table 183 "Allowable S registers" (page 468)

shows

the supported S registers allowed by the DAC. This table shows the register
number, the range accepted (decimal values shown), and a description of
the register. Whenever a register value is changed, the DAC checks for
validity. If the value entered is not within the allowed range, all processing
ceases and no command processing following the invalid entry is accepted.
The DAC sends an ERROR result message.
