Disabling And Enabling Echo Function - Teleorigin RB600 User Manual

7.5 Disabling and enabling echo function

If echo is not displayed when entering an AT command, that means:
 The local echo function in software (such as Hyperterminal) is disabled
 The echo function of the modem is disabled
To enable echo function of the modem enter the ATE1 command.
In Machine to Machine communication it is recommended to disable echo function (type
ATE0) in order to avoid non-essential CPU usage.
For further information about the AT commands and their usage, refer to [1].
