This setting is immediately stored (does not have to be stored with AT&W)
and is not reset with AT&F.
This command should not be in the same command line with other com-
mands.
Autobauding does not work with baud rates below 1200 bps.
We generally recommend not to work with autobauding, especially in con-
nection with automatic call acceptance (ATS0=<n>).
If autobauding is enabled, the TX input must not be firmly connected to
GND.
