7. Command Overview 43
with the command AT^STPB. For the formats 8E1 and 8O1, the parity bits are
generally not transmitted.
For a data rate of 300 bps, an interruption of 500 ms after <OK> must be
observed after this command until the next command is sent. For baud rates of
600 and 1200 bps the waiting period is 300 ms.
If auto bauding is active (AT+IPR=0), this also applies for the recognition of the
data format (except 8N2).

This setting is immediately saved (therefore it does not have to be saved with
AT&W), and is not reset with AT&F.
This command should not be in the same command line with other commands.
Auto bauding does not work with baud rates below 1200 bps.
In general we recommend not to work with auto bauding, especially with
automatic call acceptance (ATS0=...).
If required, we would like to refer to the more detailed AT command set of the
TC35i by Siemens, which can be obtained from INSYS Microelectronic GmbH.
