Commands
Echo Command If the MMH2834 is connected to a full-duplex computer, it may
Mode Characters be necessary for the modem to be configured to echo back
E 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 The Q command enables or disables Result Codes and the No
Enable/Disable Response Answer mode of operation. Result Codes may be
and No Response disabled altogether in certain applications, such as computer-
Answer controlled auto dialing, using the Q command. ATQ1 disables
Q 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 The MMH2834 gives you a choice between the Multi-Tech
("Multi-Tech" or Result Codes, and Result Codes that more closely match the
"Standard AT") standard AT command set responses. AT&Q1 selects AT
&Q responses with no Reliable/Compression modifiers. With this
command, the terse result code for CONNECT 2400 is 10.
