9.8. 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 (HyperTerminal) is disabled.
The Fastrack Xtend echo function is disabled.
To enable the Fastrack Xtend‟s echo function, enter the AT Command ATE1.
When sending AT Commands to the Fastrack Xtend using a communication software such as
HyperTerminal, it is recommended to:
Disable the “local echo” parameter of your communication software.
Enable the Fastrack Xtend‟s echo function (use the ATE1 command).
In a machine-to-machine communication with the Fastrack Xtend, it is recommended to disable the
Fastrack Xtend‟s echo function (using the ATE0 AT command) in order to avoid useless embedded
module processing.
Refer to document [7] Firmware 7.4a
AT Commands Manual (Sierra Wireless Software Suite
2.31)/Firmware 7.4 AT Commands Manual (Sierra Wireless Software Suite 2.30) for more information
about the ATE0 and ATE1 AT Commands.
9.9. DC-IN Detection
Refer to section 15.5 DC-IN Detection for more information on how DC-IN detection is done using AT
commands.
