Data Options and Profiles
Interactions with DTR:
If the DTR option is set to follow and Answer is set to auto, then the ADM
checks to make sure the DTR lead is on (usually indicating that your
terminal is turned on) before automatically answering the call.
If you have set the DTR option to ignore and Answer to auto, the ADM
answers data calls whether or not the DTR lead is turned on.
If the DTR option is set to follow and Answer is set to manual, the ADM
will not let you manually answer the call unless DTR is on.
Attention
Option Values: off, 3 of the same ASCII character (default = +++)
Applicable Data Protocols: All
The Attention sequence is used to take the ADM out of the Data Mode enabling
you to enter commands. The default setting is +++. You must type the
sequence rapidly (all three characters within 1.5 seconds).
Before entering the Attention sequence, there must be—at least—a one second
delay after typing your last character. Then the three characters composing the
sequence must be typed within 1.5 seconds. Finally, no additional characters
should be typed for one second after typing the Attention sequence. Failure to
comply with these guidelines results in the Attention sequence characters being
sent to the far-end as data.
To change the attention sequence to @@@, for example, type
set attention @
from an attached data terminal. Note that you need only type the new character
once while changing the value.
Possible values include any printable or control characters except

Autoadjust
Option Values: on, off
Applicable Data Protocols: All
If Autoadjust is on, the ADM automatically adjusts to the speed and parity of your
attached data terminal when you press
BREAK
, type
AT
, then press

.
After this sequence, the ADM transmits the CMD: prompt to your data terminal
with the current (new) speed and parity.
NOTE:
Failure to complete this sequence within five seconds may result in
improper speed setting.
