4.9.2 DTE-DCE character framing +ICF
This command is used to determine the local serial port start-stop
(asynchronous) character framing that the DCE shall use.
Command syntax: AT+ICF= <format>, <parity>
* <format>:
0 Autodetect not supported
1 8 Data 2 Stop supported
2 8 Data 1 Parity 1 Stop supported
3 8 Data 1 Stop supported
4 7 Data 2 Stop supported
5 7 Data 1 Parity 1 Stop supported
6 7 Data 1 Stop supported
* <parity>:
0 Odd supported
1 Even supported
2 Mark supported
3 Space supported
4 None supported
Note 1) setting a character framing different from 8N1 will disable
autobauding (in the case it was activated). However setting it back to 8N1
will not re-enable autobaud.
Note 2) setting the framing to 8N1 will let the autobauding enabled, if it
was already enabled (implying framing was already 8N1).
