#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
Note: if <state> is omitted the command returns state of the pin.
AT#V24? Read command returns actual state for all the pins in the format:
#V24: <pin1>,<state1>[<CR><LF>
#V24: <pin2>,<state2>[...]]
where
<pin n > - AT command serial port interface HW pin
<state n > - AT commands serial port interface hardware pin state
AT#V24=? Test command reports supported range of values for parameters <pin> and <state> .
