3.9.2 Command/Response
E Echoing Command Mode Characters
If the MT2834MR is connected to a full-duplex terminal or computer, you may have to
configure the modem to echo back characters typed while in 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.
Q Result Codes (Enable or Disable) and No Response Answer
The Q command enables or disables Result Codes and the No Response Answer mode of
operation.
Regarding Result Code Enable/Disable, you may want to disable the Result Codes altogether
in certain applications, such as computer-controlled autodialing. The command ATQ1
disables Result Code transmissions and ATQ0 (or ATQ) enables them. In typical operation,
the originate mode and answer mode are "intelligent" operations, controlled by the position of
the modem DIP-Switches and previously executed commands.
Regarding No Response Answer, you may want Answer mode handled without responses,
and echo turned off but want 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 enables the Result Codes to be sent.
&Q Result Codes - "Multi-Tech" or "Standard"
The MT2834MR modems give you a choice between Multi-Tech responses (which include
RELIABLE and COMPRESSED responses), and a set that more closely matches the
Standard AT command set result codes.
AT&Q0 selects Multi-Tech responses with Reliable/Compression modifiers,
DIALTONE/BUSY/NO ANSWER. With this setting, the terse response for CONNECT 2400 is
9. This is the factory default setting.
AT&Q1 selects Standard AT responses with no Reliable/Compression modifier. With this
setting, the terse response for CONNECT 2400 is 10.
Refer to Appendix D for a summary of Result Codes.
V Result Codes - Word or Digit
The V command controls whether the MT2834MR's result codes are displayed as words
("verbose") or single digits ("terse").
For example, if after dialing, no carrier signal is detected, the result can be displayed either
as NO CARRIER, or as the digit 3.
Type ATV0 (or ATV) to cause the MT2834MR to display the Result Codes as digits. Type
ATV1 to display the Result Codes as words. If you do not select a method, the factory default
setting will cause the modem to use verbose results.
X Result Codes (Basic or Extended) and Call Progress Method
The X command selects both the dialing method ("dumb" or "smart"), as well as various
response combinations related to the dialing method selected.
Regarding result code selection, you can choose to have certain responses suppressed, and
whether or not you want speed indications along with the CONNECT responses.
The MT2834MR provides "Basic" and "Extended" Result Code sets. The difference between
the two is the Basic set provides one response (CONNECT) to indicate a connection, while
