OMMANDS
Refer to ITU-T Recommendation V.25 per specification for more details on the following commands.
Fixed DTE Rate +IPR
Description: This command specifies the data rate at which the DCE will accept commands.
Syntax:
Command syntax: AT+IPR
Command Possible Responses
AT+IPR?
Note: Read syntax. +IPR: 9600
OK
Note: Current rate is 9600 bps
AT+IPR=?
Note: List of supported <rate> values,[(list
of fixed-only <rate> values)] +IPR: (0,1200,2400,4800,9600,19200), (45,50,75,
110,150,300,600,38400,57600,115200,230400)
OK
Note: Possible value (*)
AT+IPR=38400
Note: Disable autobaud and set rate to
38400 bps OK
AT+IPR=0
Note: Enable autobaud OK
(*) the first set of values indicates the range of auto-detectable speeds. The second set of
values indicates all possible speeds that can be used by the DCE. The DCE supports
Autobaud based on the data sent from the DTE.
DTE-DCE Character Framing +ICF
Description: This command is used to determine the local serial port start-stop (asynchronous) character
framing that the DCE uses.
Values: <format>
0: Autodetect (Not supported)
1: 8 Data 2 Stop (Not supported)
2: 8 Data 1 Parity 1 Stop (Not supported)
3: 8 Data 1 Stop (Supported)
4: 7 Data 2 Stop (Not Supported)
5: 7 Data 1 Parity 1 Stop (Not Supported)
6: 7 Data 1 Stop (Not Supported)
<parity>
0: Odd (Supported)
1: Even (Supported)
2: Mark (Supported)
3: None (Supported)
Note: The Rm interface is only supported at 8 data bits, No Parity, 1 stop bit. ERROR is
returned for other formats.
Syntax: Command syntax: AT+ICF= <format>, <parity>
Command Possible Responses
AT+ICF=3,3
Note: Set values. OK
Note: New values set
AT+ICF?
Note: Display current settings. +ICF: 3,3
OK
Note: Current values
AT+ICF=?
Note: Display valid parameter ranges. +ICF: (3-3),(0-3)
OK
Note: Possible values
