#V24CFG - V24 Output Pins Configuration
1 – GPIO mode: the V24 output pins can be managed through the AT#V24
command
<save> - Save V24 pin configuration:
0 – Pin configuration is not saved
1 – Pin configuration is saved
Note: when <mode>=1, the V24 pins, both output and input, can be set to
control an external GNSS receiver through the AT$GPSGPIO command.
Note: when the <save> parameter is omitted, the pin configuration is NOT
stored.
Note: changing V24 pins configuration may affect the cellular module
functionality set through AT+CFUN.
Read command returns the current configuration for all the pins (both output
and input) in the format:
#V24CF
G: <pin1
>,<mode1>[<CR><L
F><CR><LF
>
#V24CFG: <pin2>,<mode2>[...]]
Where:
<pinn> - AT command serial port interface HW pin
<moden> - AT commands serial port interface hardware pin mode
Test command reports supported range of values for parameters <pin>, <mode>
and <save>.
V24 Output Pins Control - #V24
#V24 - V24 Output Pins Control
[,<state>]
Set command sets the AT commands serial port 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” (not yet implemented)
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):
