5.3.2.10 \R - ring (RI) control
\R – ring (RI) control
Execute command
Read command
Write command
AT\R <n>
controls the RING output pin behaviour.
Parameter:
<n> = 0 - RING on during ringing and further connection
<n> = 1 – RING on during ringing
<n> = 2 - RING follows the ring signal
Note: to check the ring option status use the &V command.
Test command
Example
Reference
SW release Version A
5.3.2.11 +IPR - fixed DTE interface rate
+IPR – fixed DTE interface rate
Execute command
Read command
AT+IPR?
Returns the current value of +IPR parameter.
Write command
AT+IPR = <rate>
Specifies the DTE speed at which the device accepts commands during command
mode operation, it may be used to fix the DTE-DCE interface speed.
Parameter:
<rate> = 0/300/1200/2400/4800/9600/19200/38400/57600/115200
If <rate> is unspecified or set to 0, then automatic speed detection is enabled and also
character format (see +ICF) is set to auto-detect.
If <rate> is specified and not 0, DTE-DCE speed is fixed at that speed, hence no
speed auto-detection (autobauding) is enabled.
Test command
AT+IPR=?
Returns the supported serial port speed list.
Example
Reference V25ter
SW release Version A
5.3.2.12 +IFC - DTE - DTA flow control
+IFC – DTE-DTA flow control
Execute command
Read command
AT+IFC?
Returns active flow control settings.
Write command
AT+IFC = <by_te>, <by_ta>
Response
Selects the flow control behavior of the serial port in both directions: from DTE
to DTA (<by_ta> option) and from DTA to DTE (<by_te>)
Parameter:
<by_te> - flow control option for the data received by DTE,
<by_ta> - flow control option for the data sent by DTA
<by_te> = 0 - flow control None
<by_te> = 1 - XON/XOFF filtered
