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.
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 INSYS Modem 56k Small INT 2.0 will query the
password after CONNECT has taken place. After the password has been entered cor-
rectly, the actual CONNECT will take place and data may be transmitted. If a wrong
password was entered, the INSYS Modem 56k Small INT 2.0 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 INSYS Modem 56k Small INT 2.0 to
the application ON and OFF.
Send messages to application (default).
ATQ0
ATQ1 Don't send messages to application.
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 connec-
tion. If the value increases significantly during a connection, the quality will deteriorate.
After a previous AT%E command, an Autoretrain is performed.
