Description
Switch on pulse dialing method (deactivated for some models)
Starting with this command, each dial-up is performed with the pulse dialing method,
until an ATT or ATDT command switches it back to tone dialing.
On request, a version with pulse dialing is available for the INSYS Modem 14/336 – this
version, however, is not authorized throughout Europe.
Password query
switches the password query off after the connection has been
AT*P0
established.(default)
switches the password query on after the connection has been
AT*P1
established.
If the password query is activated, the modem will query the password after CONNECT
has taken place. After the password has been entered correctly, the actual CONNECT
will take place and data may be transmitted. If a wrong password was entered, the
modem will hang up. The password is the same as for remote control and is set with
AT*C .
Quiet control
This command toggles sending messages from the modem to the PC on and off.
Send messages to PC. (default)
ATQ0
Don't send messages to PC.
ATQ1
Display telephone call quality
Displays the quality of the data connection (deviation from the eye diagram). Low
values indicate a good line quality. The line quality value must be evaluated differently
depending on the negotiated data rate.
Connections with more than 9600 baud will reach the value "000" for good lines and
should not have values of more than "010".
For connections with 33600 baud good lines will have values between 010...030.
Depending on the settings and the modulation type a fall back or retrain is triggered if
the line quality is too bad to enable a new negotiation of the connection (if necessary
with a slower speed).
High values indicate bad quality. These values are constantly updated during a
connection. If the value increases significantly during a connection, the quality will
deteriorate. After a previous AT%E command, an Autoretrain is performed.
