CTS

CTS Control

Determines how the modem sets the CTS signal. The modem signals the DTE with CTS on
EIA/TIA 232-D Pin 5 (V.24 Circuit 106). The CTS Signal discussed here is the state of the
CTS signal after the setting of the modem’s RTS option has been followed. For CTS to follow
the RTS signal from the DTE, set the modem RTS= Normal.

AT

*

CT3

=AsyncSync

CTS is on in asynchronous mode. CTS is off in synchronous, ACU mode. If the data transfer
mode is synchronous, CTS is off during training/retraining 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).

CT0

CTS=High

CTS remains high at all times. Use this option with RTS/CTS or DTR/CTS Flow control.

DSR

DSR Control

Determines how the modem sets the DSR signal. The modem signals the DTE with DSR on
EIA/TIA 232-D Pin 6 (V.24 Circuit 107).

AT&S0

=High

DSR is always on.

AT&S1

=Normal

DSR is controlled by the modem.

AT&T0

TEST

=End Test

Test

Ends the test currently in progress for each test listed below (except retrain).

AT&T1

=LAL

Initiates a local analog loopback test.

AT&T3

=LDL

Initiates a local digital loopback test.

AT&T4

Accept RDL

=On

Accept RDL

The local modem can be put into a remote digital loopback test.

AT&T5

=Off

The local modem cannot be put into a remote digital loopback test.

AT&T6

TEST=RDL

Initiates a remote digital loopback test.

AT&T7

TEST=RDL Pat

Initiates a remote digital loopback pattern test.

AT&T8

TEST=LAL Pat

Initiates a local analog loopback pattern test.

Long Form

Status

Modem Status Display

Lets you view modem status information, on the control terminal, in long form. The display
shows operating status, DTE/DCE rate/status, asymmetric rates status, connect message status,
the data form, throughput-delay minimization status, error correction status, data compression
status, EIA/TIA signal status, disconnect reasons, the software revision level, and CQMS
parameters. The long form also shows front panel options and corresponding AT commands.

AT&V1

Short Form

Status

Lets you view modem status information, on the control terminal, in short form. This displays
a summary of AT command settings and S-register values.

Save Changes

Save Changes

When using AT Commands or front panel options to alter modem settings, if you do not save
the changes, the modem does not enter them into memory. After you have selected the option
set for your application (using the ATZn Command), and modified configuration settings,
enter: AT&Wn where n=(Option Set) 1 through 4. The modem displays Saving Options, then
Save Completed! signifying that the option set has been saved in nonvolatile memory.

AT&W0/
AT&W1

=1

Save changes to Option Set 1.
