To read back a value, use the READ command:
+CMD?
To test if a particular command is supported, along with the range of values it supports, use the
TEST command:
+CMD=?
An extended command must be terminated with a semicolon if another command follows it in the
same command line. Table 10.5 describes the extended AT configuration commands.
Table 10.5: Extended AT Configuration Commands
Command Description
+IFC
TE2-MT2 Local Flow Control.
This extended-format compound parameter is used to control the
operation of local flow control between the TE2 and the MT2. The format
is:
AT+IFC=<DCE_by_DTE>,<DTE_by_DCE>
Where:
<DCE_by_DTE> Specifies the method to be used by the DTE to control the
flow of received data from the DCE
<DTE_by_DCE> Specifies the method to be used by the DCE to control
the flow of transmitted data from the DTE
The valid numeric variables for the +IFC command are as follows:
0 No Flow Control
1 Xon/Xoff
2 Hardware
By default, the modem is set up as AT+IFC=2,2 to allow hardware flow
control in both directions
+IPR
Fixed Rm Rate.
This numeric extended-format parameter specifies the data rate at which
the MT2 will accept commands, in addition to 1200 bps or 9600 bps (as
required in EIA/TIA-602). It may be used to select operation at rates at
which the MT2 is not capable of automatically detecting the data rate
being used by the TE2. Rm default rates set at 115.2Kbps
+ICF
Local RS-232 Interface Character Framing.
This parameter determines the character framing used at the local RS-232
interface. The syntax is: AT+ICF=<format>,<parity>
Where:
<format> is a single digit and determines the number of data bits, the
presence of a parity bit, and the number of stop bits in the start-stop
frame according to the following values:
<format> Meaning
1 8 Data, 2 Stop
2 8 Data, 1 Parity, 1 Stop
3 8 Data, 1 Stop
<parity> is a single digit and determines how the parity bit is generated
and checked, if present, according to the following values:
<parity> Meaning
0 Odd
1 Even
