Communicating with the GL8200
4.6. Echo Function
If no echo is displayed when entering an AT command, it could mean either of the following:

The "local echo" parameter of your communication software such as HyperTerminal, is
disabled.

The GL8200 echo function is disabled.
To enable the GL8200 echo function, enter
ATE1
.
When sending AT commands to the GL8200 through a communication software such as
HyperTerminal, it is recommended to:

Disable the "local echo" parameter of your communication software

Enable the GL8200 echo function (
ATE1
command)
In a machine-to-machine communication with the GL8200, it is recommended to disable the GL8200
echo function (
ATE0
command) in order to avoid useless CPU processing.
For more information about AT commands applicable to the GL8200, please refer to the commands
marked as supported by HL8548x in document [2] AirPrime HL6 and HL8 Series AT Commands
Interface Guide.
