Function and Description
Data Terminal &D determines how the modem responds to the DTR signal from the terminal. The country
Ready Options configuration may prevent the modem from detecting terminal DTR. In this case, the
modem assumes DTR is always on. In North America, terminal DTR is normally detected. If DTR detection
The response to changes in DTR also depends on the &Q and &D commands. This table defines what
happens when DTR goes off for all possible combinations of the &D and &Q commands. To see what
happens when DTR goes on refer to the &Q command. The default value is &D0 in North America:

Command Mode E tells the modem whether or not to echo characters sent from the terminal when the
modem is Character Echo 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 their 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
S6=2 S7=30
S12=50

&G tells the modem which guard tone to transmit when the modem is transmitting the high band (i.e.,
answer handshake and answer mode).

&G1
&G2
has been prevented, the modem will respond with an ERROR result to this command.
E1
The modem hangs up the telephone line and issues an OK result code.
If in the On-Line state, the modem goes into the Command state and issues an OK result code.
The modem hangs up the telephone line and issues an OK result code. Auto-Answer is disabled as
long as DTR stays off.
The modem resets.
Does not echo characters sent from the terminal.
Echo characters sent from the terminal. This is the default value in North America.
Initiate a retrain if the datapump indicates one is required.
No guard tone. This is the default value in North America.
550 Hz guard tone (V.22 and V.22bis only)
1800 Hz guard tone (V.22 and V.22bis only)
Do not initiate a retrain.
