Multi-Tech Systems DT101/xx Command Response Result Code Commands, Echo Command Mode Characters

DataTalker Owner’s Manual

F.6 Command Response (Result Code) Commands

Echo Command Mode Characters E

If the MMH2834 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 Resul 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 MMH2834 gives you a choice between the Multi-Tech Result Codes and Result Codes that more closely match the standard AT command set responses. AT&Q1 selects AT responses with no Reliable/Compression modifiers. With this command, the terse result code for CONNECT 2400 is 10.
