INSYS Modem 336 LL 2D/4D 5.x Originate / Answer

Command Description

ATQ<n>

Quiet control

This command toggles sending messages from the INSYS Modem 336 LL 2D/4D 5.x
Originate / Answer to the application ON and OFF.

ATQ0

Send messages to application (default)

ATQ1

Don't send messages to application

AT%Q

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.

AT&R<n>

RTS/ CTS behavior

This command determines how the INSYS Modem 336 LL 2D/4D 5.x Originate / Answer
treats the RTS/CTS (CT105/CT106) data flow control lines.

(see also command

AT&K

).

AT&R0

CTS behavior complies with V.25bis. CTS is deactivated during the con-
nection setup after recognition of the response or ringing tones and will
only be activated after the connection is set up. During the controlled
half duplex operation (

AT&K8

) CTS is active, if the INSYS Modem 336 LL

2D/4D 5.x Originate / Answer sends data at the serial interface. When
data is received at the serial interface, CTS is inactive.

AT&R1

CTS only switches to OFF when this is required by the data flow control.
During the controlled half duplex operation (

AT&K8

) CTS is inactive, if

the INSYS Modem 336 LL 2D/4D 5.x Originate / Answer sends data at
the serial interface. When data is received at the serial interface, CTS is
active.

(default)

AT*R<n>

Switches the remote control on and off

AT*R0

Switches the remote control OFF

AT*R1

Switches the remote control ON (default)
