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 number
is not detected by the INSYS Modem 56k Small INT 2.0, 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 \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 Small INT 2.0 treats the RTS/CTS
(CT105/CT106) data flow control lines.
(See also command AT&K).
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 controlled
half duplex operation (AT&K8) CTS is active, if the INSYS Modem 56k
Small INT 2.0 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 56k Small INT 2.0 sends data at the serial interface.
When data is received at the serial interface, CTS is active. (default)
Switches the remote control on and off
Switches the remote control OFF.
AT*R0
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 Small INT 2.0 still reports OK although the value has not
changed. 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.
ATS<n>?
Shows the value of the S registry n.
