Description
Password query
AT*P0 Switches the password query off after the connection has been estab-
lished (default).
AT*P1 Switches the password query on after the connection has been estab-
lished.
If the password query is activated, the modem will query the password after CON-
NECT has taken place. After the password has been entered correctly, the actual CON-
NECT will take place and data may be transmitted. If a wrong password was entered,
the modem will hang up.
This is set using AT*C. The passwords for the connection setup and
Note:
the remote control are the same.
Quiet control
This command toggles sending messages from the modem to the application ON and
OFF.
ATQ0 Send messages to application (default).
Don't send messages to application.
ATQ1
Display telephone call quality
Displays the quality of the data connection (deviation from the eye diagram). Low val-
ues 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. De-
pending 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 con-
nection. If the value increases significantly during a connection, the quality will dete-
riorate. After a previous AT%E command, an Autoretrain is performed.
