&Bn – DTR Dial Option
This command interprets the OFF to ON transition of the DTR signal from the DTE to enable the
modem to dial the telephone number stored with ATZ0=...... The parameter value, if valid, is written
to S27 bits 7.
&B0 No action. (Default.)
&B1 Dial on OFF to ON transition of the DTR signal.
Please also refer to AT&Z and AT&D.
\Bn – Transmit Break to Remote
In non-error correction mode, the modem will transmit a break signal to the remote modem with a
length in multiples of 100 ms according to parameter specified. If a number in excess of 9 is entered,
9 is used. The command works in conjunction with the \K command.
In error correction mode, the modem will signal a break through the active error correction protocol,
giving no indication of the length.
\B1-\B9 Break length in 100 ms units. (Default = 3.)
Note: When the modem receives a break from the remote modem, break is passed to the DTE as
follows: In non-error correction mode direct, the break length is passed; in non-error correction mode
normal and in error correction mode, a 300 ms break is passed.
&Cn – DCD Option
The modem controls the DCD output in accordance with the parameter supplied. The parameter
value, if valid, is written to S21 bit 5.
On leased line DCD always follows the state of the carrier.
&C0 DCD remains ON at all times. (Default.)
&C1 DCD follows the state of the carrier.
%C – Enable/Disable Data Compression
Enables or disables data compression negotiation. The modem can only perform data compression on
an error corrected link. The parameter value, if valid, is written to S41 bits 0, 1 and S46 bit 1.
%C0 Disables data compression.
%C1 Enables MNP 5 data compression negotiation.
%C2 Enables V.42 bis data compression.
%C3 Enables both V.42 bis and MNP 5 data compression. (Default)
Please also refer to AT\Nn.
*Cn – Password for remote control
This command directs the modem to ask for a password, ”ENTER PASSWORD”. In order to execute
remote configuration the calling modem will have to present the password before making any
editing. The password must consist of between 6 and 12 letters. The default setting is ”QWERTY”.
This command is available only for MNP connections.
Please also refer to AT\Nn, AT*E and AT*R.
Not available in remote programming mode (AT*R)
