E
Command Mode
Character Echo
E tells the modem to echo or not echo characters sent from the terminal while the modem
is accepting AT commands.
E0
Does not echo characters sent from the terminal.
E1
Echo characters sent from the terminal. This is the default value in North
America.
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
Do not initiate a retrain.
%E1
Initiate a retrain if the datapump indicates that one is required.
&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 S1=0 S2=43 S3=13 S4=10 S5=8
S6=2 S7=30 S8=2 S9=6 S10=14 S11=95
S12=50 S17=10 S25=5 S28=0 S29=25 S37=0
Commands
B1 E1 M1 P Q0 V1 X4 &C0 &D0 &G0 &P0 &Q0 %E1
&G indicates the modem which guard tone to transmit when the modem is transmitting
the high band (that is, answer handshake and answer mode).
&G0
No guard tone. This is the default value in North America.
&G1
550-Hz guard tone (V.22 and V.22bis only)
&G2
1800-Hz guard tone (V.22 and V.22bis only)
H0
Hangs up the telephone line.
H1
Goes off hook without answering a telephone call. This may be disabled in
countries prohibiting its use.
%E
Automatic Retrain
