Chapter 3 – Supported GSM/WCDMA AT Commands
High Speed HSPA-H4 AT Commands Reference Guide (Document S000483A) 51
+ICF DTE-DCE Character Framing
Description: This command determines the local serial port start-stop (asynchronous) character framing
used by the DCE.
Syntax:
Command Responses
Action Command:
AT+ICF=<format>[,<parity>]
OK
Read Command:
AT+ICF?
AT+ICF: <format>,<parity>
OK
Test Command:
AT+ICF=?
AT+ICF: (list of supported <format>s),
(list of supported <parity>s)
OK
Values: <format> Character Framing Format
1 8 Data 2 Stop
<parity> parameter is ignored
2 8 Data 1 Parity 1 Stop
If no <parity> provided, 3 is used by default as <parity> value
3 8 Data 1 Stop
<parity> parameter is ignored. Default.
4 7 Data 2 Stop
<parity> parameter is ignored
5 7 Data 1 Parity 1 Stop
If no <parity> provided, 3 is used by default as <parity> value
6 7 Data 1 Stop
<parity> parameter is ignored
<parity> Character Framing Parity
0 Odd
1 Even
2 Mark
3 Space
4 None. Default.
Parameter Storage: The <format> and <parity> parameters are stored in EEPROM using AT&W
command. The default value can be restored using AT&F.
Examples:
Command Responses
AT+ICF=? +ICF: (1-6),(0-4)
OK
Note: Possible values
AT+ICF=2,0 OK
Note: New values
AT+ICF? +ICF: 2,0
OK
Note: Current values
Notes: All framing settings of the serial interface (i.e., 801, 8E1, 8S1, 8N1, 7N1, 7O1, 7E1, 7S1 and
7N2) are supported for autobaud mode.
If USB port is used:
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.
