#V24CFG - V24 Output Pins Configuration
AT#V24CFG=<pin>,
<mode>
Set command sets the AT commands serial port (UART) interface output pins
mode.
Parameters:
<pin> - AT commands serial port interface hardware pin:
0 - DCD (Data Carrier Detect)
1 - CTS (Clear To Send)
2 - RI (Ring Indicator)
3 - DSR (Data Set Ready)
<mode> - AT commands serial port interface hardware pins mode:
0 - AT commands serial port mode: output pins are controlled by serial port device
driver. (default)
1 - GPIO mode: output pins are directly controlled by #V24 command only.
AT#V24CFG?
Read command returns actual mode for all the pins in the format:
#V24CFG: <pin1>,<mode1>[<CR><LF><CR><LF>
#V24CFG: <pin2>,<mode2>[...]]
Where:
<pinn> - AT command serial port interface HW pin
<moden> - AT commands serial port interface hardware pin mode
AT#V24CFG=?
Test command reports supported range of values for parameters <pin> and
<mode>.
3.5.5.1.46. V24 Output Pins Control - #V24
#V24 - V24 Output Pins Control
AT#V24=<pin>
[,<state>]
Set command sets the AT commands serial port (UART) interface output pins state.
Parameters:
<pin> - AT commands serial port interface hardware pin:
0 - DCD (Data Carrier Detect)
1 - CTS (Clear To Send)
2 - RI (Ring Indicator)
3 - DSR (Data Set Ready)
4 - DTR (Data Terminal Ready). This is not an output pin: we maintain this
value only for backward compatibility, but trying to set its state raises the result
code “ERROR”
5 - RTS (Request To Send). This is not an output pin: we maintain this value
only for backward compatibility, but trying to set its state raises the result code
“ERROR”
<state> - State of AT commands serial port interface output hardware pins (0, 1, 2,
3) when pin is in GPIO mode (see #V24CFG):
0 - Low
1 - High
