5.4.5 Command Response (Result Code) Commands
Echo Command Mode Characters E
If the modem is connected to a full-duplex computer, it may be necessary for the modem to be
configured to echo back characters entered while in the Command Mode in order for them to be
displayed. The E command is used to configure the Command Mode echo, with ATE0 disabling the
echo and ATE1 enabling the echo (default).
Result Codes Enable/Disable and No Response Answer Q
The Q command enables or disables Result Codes and the No Response Answer mode of operation.
Result Codes may be disabled altogether in certain applications, such as computer-controlled auto
dialing, using the Q command. ATQ1 disables Result Code transmissions. ATQ0 (or ATQ) enables
Result Code transmission.
Regarding No Response Answer, you may want the answer mode handled without responses and
echo turned off, but want the originate mode still intelligent. This is called the No Response Answer
mode. ATQ2 selects the No Response Answer mode. If you do not select any mode, the factory
default setting (enable Result Codes) is automatically selected.
Result Codes ("Multi-Tech" or "Standard AT") &Q
The modem gives you a choice between the Multi-Tech Result Codes, and Result Codes that more
closely match the standard AT command set responses (see
Section 5.3 ).
AT&Q1 selects AT responses with no Reliable/Compression modifiers. With this command, the
terse result code for CONNECT 2400 is 10.
AT&Q0 selects Multi-Tech responses with Reliable/Compression modifiers. With this command, the
terse result code for CONNECT 2400 is 9.
Result Codes (Verbose/Terse) V
The V command controls whether the modem’s result codes are displayed as word (“verbose”) or
single digit (“terse”) messages.
For example, if after dialing, no carrier signal is detected, the resulting message can be displayed
either as NO CARRIER, or as the digit 3.
Entering ATV0 (or ATV) causes the modem to display the Result Codes as digits, while ATV1
displays them as words. If you do not select a method, the factory default setting causes the modem
to display Result Codes as words.
