HSPA+ AT Commands Reference Guide
V24 Output Pins Control #V24
Set command sets the AT commands serial port interface output pins state.
Read command returns actual state for all the pins—output or input—in the format:
#V24: <pin1>,<state1>[<CR><LF>
#V24: <pin2>,<state2>[...]]
where
<pinn> ‐ AT command serial port interface HW pin
<staten> ‐ AT commands serial port interface hardware pin state
Test command reports supported range of values for <pin> and <state>.

Parameters and Values
<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: value is maintained 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. The value is maintained only for
backward compatibility. 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
Notes
If <state> is omitted the command returns the actual state of the pin <pin>.
GPRS Auto‐Attach Property #AUTOATT
Set command enables or disables the TE GPRS auto‐attach property.
Read command reports whether the auto‐attach property is currently enabled or not, in the format:
#AUTOATT: <auto>
Test command reports available values for parameter <auto>.
