S91 ECM Mode for FAX Operation
register values / default description
S91 0, 1 / 1 ECM mode for fax operation
0 no error correction
1 error correction
If your fax software does not support the ECM mode you can activate
error correction by typing the command ATS91=x using a terminal. Data
protection is disabled if register S91 is set to 0. If the register is set to 1
the modems support data protection. The modems negociate during dial
up if the connection is performed with data protection.
The duration of an error protected connection may be up to 30% longer
as transmitted data is permanently acknowledged during ECM mode.
The setting of register S91 is overwritten if your fax software employs
the AT+FECM command.
Any alterations of the register contents only get active after POWER ON
or with the ATZ command. The changed register value has to be saved
with AT&W(n).
S100 Echo Character at Password Protection
register values / default description

(ASCII „*“, 2Ahex) protection
The register specifies the echo character to be retransmitted after
password inquiry to the calling station. The factory default is „*“. Character
echo is disabled if 0 is selected.
S101 Password Protection Counter
The register content is augmented by the value 1 after every dis-
connection that was caused by an invalid password thus allowing to
protect the DTE against unauthorized accesses. The register is reset at
POWER ON or by typing ATS101=0.
