Description
Quiet Call
Quiet Call will switch of the phone connected in series at the first ring. In connec-
tion with the selective call answer (AT&N<n>), calls from a previously defined
phone number can take place without a ring of the phone connected in series. If
the phone number is not detected by the INSYS Modem 56k AC/DC 4.2, the
phone is switched on again after the first ring.
AT\Q0
Switches Quiet Call off (default)
AT\Q1
Activates Quiet Call. The phone connected in series is discon-
nected, as soon as an entire ring signal cycle is detected on the line.
AT\Q2
Activates Quiet Call. The phone connected in series is
disconnected, as soon as a ring signal flank is detected on the line.
The selection between the settings \Q1 or \Q2 depends on the circumstances at
the phone connection. For \Q2 in connection with pulse dialing, phones that are
connected in parallel will sometimes result in an erroneous detection of a ring
signal flank. When using pulse dialing at the phones connected in series, AT\Q1
must be used.
RTS/ CTS behavior
This command determines how the INSYS Modem 56k AC/DC 4.2 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
connection setup after detection 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 56k AC/DC 4.2 sends data at the serial interface. When da-
ta 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 56k AC/DC 4.2 sends data at the se-
rial interface. When data is received at the serial interface, CTS is
active. (default)
Switches the remote control on and off
AT*R0
Switches the remote control OFF.
AT*R1
Switches the remote control ON (default).
Read/write of the S registry
Depending on the country settings, the S registries may only be changed within
certain limits. The INSYS Modem 56k AC/DC 4.2 still reports OK although the val-
ue has not changed. We recommend checking the results after each write at-
tempt, using the ATS<n>? command.
ATS<n>=<x> Sets the S registry n to the value x.
ATS<n>? Shows the value of the S registry n.
