Local Echo
Description:
The Set Local Echo command permits the user to select whether the modem should echo the characters
sent to it back to the host. For some applications, local echo is not required as the host does not need to
confirm what has been sent to the modem. For terminal operation, local echo can be used to verify what
has been sent to the modem and aids in sending commands, since each keystroke is displayed on the
terminal.
Format:
ATE0
Disable Local Echo
ATE1
Enable Local echo
Validity:
Changes to the local echo setting are valid during program or AT command modes. Changes made while
not in program mode will be lost upon power down. Changes made and saved while in program mode will
be retained by the modem.
Other Considerations:
For a wide variety of applications, local echo is not required or desired. When using local echo with a
terminal, it is wise to keep in mind that the application being used may require local echo to be off rather
than on. Always ensure that the echo setting is set in the proper mode for the application when re-
installing a modem.
