Chapter 5 – Configuring and Communicating with
Your Device
Before Using the Device
Before using the device:
Install any drivers. Refer to the separate driver installation guide for your device.
Power up your device and ensure it is connected to your computer that issues AT commands.
Note:
Wait 10 seconds after power-up before issuing any AT commands.
Install terminal software that can communicate with the device, such as HyperTerminal, Tera Term, Kermit,
or Putty.
For additional information, refer to the AT Command Reference Guide for your device. The guide describes
command formatting, syntax, and other basic information.
Using Command Mode and Online Data Mode
Modems have two operation modes, command and online data. After power up, the modem is in command mode
and ready to accept AT commands.
Use AT commands to communicate with and configure your modem. These commands establish, read, and modify
device parameters and control how the modem works. The device also generates responses to AT commands that
help determine the modem’s current state.
If the modem is in online data mode, it only accepts the Escape command (+++).
To send the modem AT Commands from terminal emulation software, set the software to match the modem’s
default data format, which is:
Speed: 115,200 bps
Data bits: 8
Parity: none
Stop bit: 1
Flow control: hardware
To confirm communication with the device:
Type
AT
and press
Enter
.
If the device responds with OK, it is properly communicating.
