Function and Description
E tells the modem to echo or not echo characters sent from the terminal while the modem
is accepting AT commands.
E0
E1
The %E command controls whether the modem will initiate retrain 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
%E1
&F changes these AT command options and S-registers to default
values. The default values may be changed for use in different countries. The values for
North America are:
S-registers
S0=0
S6=2
