Examples:
Notes:
This command determines the local serial port start-stop (asynchronous) character framing
used by the DCE.
<parity>
All framing settings of the serial interface (i.e., 801, 8E1, 8S1, 8N1, 7N1, 7O1, 7E1, 7S1 and
7N2) are supported for autobaud mode.

The <format> and <parity> parameters are stored in EEPROM using AT&W
command. The default value can be restored using AT&F.
The action command is supported for compatibility reasons (but without effect).
The response to the action command and the read command behavior is the
same as if sent on UART1 or UART2.
