Description
DTR (CT108/2) behavior
DTR (CT108/2) behavior - Monitoring on/off transitions of the RS232 DTR line of the PC.
DTR is ignored. Allows the operation with PCs which do not run DTR.
AT&D0
AT&D1 A DTR on/off transition causes the INSYS Modem 56k Small INT 2.0 to
react as if it had received an abort sequence +++. The INSYS Modem 56k
Small INT 2.0 switches to the input mode without hanging up.
AT&D2 A DTR on/off transition causes the INSYS Modem 56k Small INT 2.0 to
hang up. Going off-hook automatically is not possible. (default)
A DTR on/off transition causes the INSYS Modem 56k Small INT 2.0 to
AT&D3
perform a reset as if an ATZ command had been executed. A preceded
AT&Y command decides if either the default 0 or 1 is loaded.
Activate/deactivate V.42bis data compression
AT+DS=0 Deactivates V.42bis data compression
AT+DS=3 Activates V.42bis data compression (default)
Activate/deactivate V.44 data compression
Deactivates V.44 data compression
AT+DS44=0
Activates V.44 data compression (default)
AT+DS44=3
Command entry Echo
This command toggles the responses, which the INSYS Modem 56k Small INT 2.0 cre-
ates as reactions from application commands (Echo), ON or OFF.
Switch off Echo
ATE0
ATE1 Switch on Echo (default)
Automatic Retrain
When transmission problems occur, the INSYS Modem 56k Small INT 2.0 executes a
retrain procedure. After three unsuccessful retrain attempts, the INSYS Modem 56k
Small INT 2.0 will hang up.
Retrain not allowed
AT%E0
AT%E1 Retrain allowed
AT%E2 Fall back, fall forward allowed (default)
Terminate remote configuration
The command AT*E terminates a remote configuration.
Loading the default factory settings
The INSYS Modem 56k Small INT 2.0 loads the default factory setting from the internal,
nonvolatile memory. This puts the INSYS Modem 56k Small INT 2.0 into a defined basic
state. AT&F also overwrites a part of the S registry.
The INSYS Modem 56k Small INT 2.0 has the following two defaults: (AT&F0, AT&F1).
