B-26
2 =DTR Dial. On a de-asserted-to-asserted DTR
transition, the modem dials the Phonebook number
specified by the Default Dial option. The modems
transmit data synchronously. If DTR transitions from
asserted to de-asserted, the modem hangs up and enters
asynchronous command mode.
&P Pulse Cycle
0 =40%.The make/break ratio is 40:60.
1 =33%. The make/break ratio is 33.5:66.5.
2 =38%. The make/break ratio is 38.5:61.5.
&R CTS Control
Determines how the modem sets CTS signal. The
modem signals the computer with CTS on EIA/TIA
232-D Pin 5 (V.24 Circuit 106). This is the state of the
CTS signal after the modem’s RTS setting is followed.
0 =High. CTS is always asserted. Use this option with
RTS/CTS or DTR/CTS Flow control.
1=Normal
2 =ACU On
3
=AsyncSync. CTS is asserted in asynchronous mode.
CTS is de-asserted in synchronous, ACU mode. If the
data transfer mode is synchronous, CTS is de-asserted
during training and follows RTS in data mode. When
CTS follows RTS in data mode, the setting of the RTS/
CTS Delay option applies (if Mode=Direct).
4=RTS
&S DSR Control
Determines how the modem sets the DSR signal.
0 =High. DSR is always asserted.
1 =Normal. DSR is controlled by the modem.
2=DTR
3 =Drop on Disconnect
4 =Simulate Leased Line
AT Command Set (continued)
Command Option Description
The characters AT or at precede all commands except: +++, #####, and A/
Parameters and options shown shaded gray vary by country. For your country’s options,
refer to the 3460 Fast’R Reference Guide (T0022).
Default (pre-set) options are underlined.
