Command mode

Use a COM port terminal in order to communicate with the device. We use the HERCULES COM port soft terminal
available to download for free by clicking on the following link:
dex_en.html
• With Hercules, select the "Serial" tab, then configure the serial port with the following serial parameters:
Parameters
Rate
Parity
Data
Stop Bit
• Select the serial port on which the device has been created with Windows (Name).
• Click on the "Open" button to open the serial port.
NOTE INFORMATION: If the com port has been opened correctly, Hercules will display the message
"Serial COM3 port opened". Alternatively, "Serial port com opening error" will be displayed, meaning
either that the com port is already open for another application, or it does not exist.
Write '+++' to execute the configuration mode..
On the com port terminal, you should also have «CONNECT-
ING...» and « CM » feedback for Command Mode.
Sending a character on Hercules is displayed in magenta and
receiving a character is displayed in black. If you do not see
sending characters, this is probably because ECHO is not active
on this program. To activate the option in the accessible menu,
right click in the viewing window.

3.3. AT commands

A command starts with 2 ASCII characters: "AT", followed by one or more characters and data (see the
list below for the syntax of AT commands available on the modem).
Each command must finish with a "CR" or "CR" "LF" – both are acceptable.
(CR indicates: Carriage Return, LF indicates: Line Feed)
Once the command has been received, the modem will feedback:
<cr><lf> "Data" for ATS type playback control <n> ?, AT/S or AT/V
"O" <cr><lf>, for any other command when this has been accepted.
"E" <cr><lf>, if it refuses the command due to a syntax error, unknown command, unknown range,
invalid parameter, etc.
"CM" <cr><lf>, if it accepts the input in command mode
