Description
Quiet Call
Quiet Call will switch of the phone connected in series at the first ring. In connection
with the selective call answer (AT&N<n>), calls from a previously defined phone num-
ber can take place without a ring of the phone connected in series. If the phone num-
ber is not detected by the modem, the phone is switched on again after the first ring.
Switches Quiet Call off (default)
AT\Q0
AT\Q1 Activates Quiet Call. The phone connected in series is disconnected,
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 AT\Q1 or AT\Q2 depends on the circumstances
at the phone connection. For AT\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 modem treats the RTS/CTS (CT105/CT106) data
flow control lines.
(See also command AT&K<n>).
CTS behavior complies with V.25bis. CTS is deactivated during the con-
AT&R0
nection setup after recognition of the response or ringing tones and
will only be activated after the connection is set up. During the con-
trolled half duplex operation (AT&K8) CTS is active, if the modem sends
data at the serial interface. When data is received at the serial inter-
face, CTS is inactive.
CTS only switches to OFF when this is required by the data flow con-
AT&R1
trol. During the controlled half duplex operation (AT&K8) CTS is inac-
tive, if the modem sends data at the serial interface. When data is re-
ceived at the serial interface, CTS is active. (default)
Switches the remote control on and off
AT*R0 Switches the remote control OFF.
Switches the remote control ON (default).
AT*R1
Read/write of the S registry
Depending on the country settings, the S registries may only be changed within cer-
tain limits. The modem still reports OK although the value has not changed as speci-
fied. We recommend checking the results after each write attempt, using the
ATS<n>? command.
ATS<n>=<x> Sets the S registry n to the value x.
Shows the value of the S registry n.
