Description
AT+ICF=<format>
[,<parity>]
Querying the data format of the serial interface
<

1
8 data bits, no parity bit, 2 stop bits
2
8 data bits, 1 parity bit, 1 stop bit
3
8 data bits, no parity bit, 1 stop bit
4
7 data bits, 1 parity bit, 1 stop bit

The <

The following settings are supported:
AT+ICF=5,1
7E1
AT+ICF=5,0
7O1
AT+ICF=2,1
8E1
AT+ICF=3
8N1 (default)
AT+ICF=2,0
8O1
AT+ICF=1
8N2
The parity bit is not transferred to the remote terminal by default with the
settings 7E1 and 7O1. If this would be necessary, an additional setting
must be made with the command
AT^STPB
. The parity bits are generally
not transferred with the commands 8E1 and 8O1.
A pause of 500 ms must be maintained following the <OK> before sending
the next command for a data rate of 300 bps. A pause of 300 ms is re-
quired for baud rates of 600 and 1200 bps.
If autobauding is enabled (
AT+IPR=0
)
, this is also valid for the data format
detection (except 8N2).
