CUSTOM AT COMMANDS

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>.
