You can use the AT%Fn command to control the data format.
You can use the AT%C
n
command to control whether and when to apply
changes to the configuration
Example:
Sending
AT%C1
will cancel any changes made to the modem
during a remote access session and restore it to the original
configuration.
Even though, by default (%C0), the changes you make do not take effect
until the next connection, the new configuration is reflected immediately
in inquiry responses (ATIn).
Commands that have been written to NVRAM (using &W) and forced
configuration changes (%C2) will not be restored to their previous
settings when you send the host AT%C1.
After you make changes to the host’s configuration, the remote- access
prompt changes from
Remote->
to
Remote+>
.
To change the data format to Command
No Parity (8 data bits)
AT%F0
Mark parity (7 data bits)
AT%F1
Odd Parity (7 data bits)
AT%F2
Even parity (7 data bits)
AT%F3
For your modem to Command
Defer configuration changes to when the call
ends.
AT%C0
(Default)
Restore the original configuration.
Use this command to cancel any changes made
during remote access and restore the original
configuration.
AT%C1
Force configuration changes.
Use this command to make configuration changes
take effect immediately. We do not recommend
forcing changes unless it is absolutely necessary
because an unreliable connection, or even a loss
of connection, may result.
