AT Commands for EV-DO-EV3 Modems
112
#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.
Test command reports supported range of values for <pin> and <mode>.
Syntax
Command Command type
AT#V24CFG=<pin>,<mode> Set
AT#V24CFG? Read
AT#V24CFG=? Test
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). Not supported.
4 DTR (Data Terminal Ready). This is not an output pin. Value is maintained for
backward compatibility. Trying to set its state raises the result code ERROR. Not
yet implemented.
5 RTS (Request To Send). This is not an output pin. Maintained only for backward
compatibility. Trying to set its state raises the result code ERROR.
<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: 0.
1 GPIO mode: output pins are directly controlled by #V24 command only.
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>.
