Function and Description
This command enables or disables character echoing sent from the terminal
when the modem is accepting AT commands.
E0
Does not echo characters sent from the terminal.
E1
Echoes characters sent from the terminal. This value is the
default value in North America.
The %E command enables or disables retraining with the other modem during
a telephone line connection (during operation in data modes supporting
retrain). The modem always responds to a retrain operation initiated by the
remote modem. The modem can be forced to initiate a retrain by the ON-LINE
(O1) command.
%E0
Retrain is not initiated automatically.
%E1
Retraining is initiated if the data pump indicates retraining is
required. This value is the default value.
&F changes these AT command options to their default values. The default
values may be changed for use by country.
