23.When a timeout is written with a 0x0000 value using either the WriteConfig_Request or the AccessDB_Request command, this timeout
will not be activated.
24.After a AccessDB_Request for either the Timeoutnotaddressed or the Timeoutframenotok, the new value is immediately taken in
account (the timeout is restarted) except when the local MAC address is NEW and the initiator MAC address is nobody.
25.The envelops are calculated using square root values or absolute values, depending on the baud rate and on the main frequency. The
following table describes the different modes:
300, 600, 1200 bps
2400 bps

26.When FSK+ option is enabled, new thresholds are calculated. Than if the two envelops are under the threshold, the envelop which has the
smallest gap with his threshold is used to determinate which bit is received. Or, if the two envelops are over the threshold, the envelop which
has the biggest gap with his threshold is used.
7.3.3 WriteConfig_Confirm
<STX>
0x26 (Length)
0x72 (WriteConfig_Confirm)
Data_Config_Echo
CHK
When the complete set of configuration parameters has been evaluated and stored by the MODEM, it replies with success
and echoes the configuration data for the external processor to see if all parameters are correctly stored.
7.3.4 WriteConfig_Error
<STX>
0x04 (Length)
0x73 (WriteConfig_Error)
Error_Code, Table 43
CHK
An error is raised when the external processor issues a WriteConfig_Request command in which the fields listed in Table 42
are modified with respect to the previously issued WriteConfig_Request command. All other data fields of the
WriteConfig_Request may be changed.
