Result codes:
This document describes the AT commands and S registers supported in the
USRobotics 56K Softmodem. Presentation format for each command has a
standard layout consisting of the following:
• A command title.
• A general command description.
• Result codes including the conditions for obtaining the result.
• A detailed command description.
The command title is formatted in large bold letters and contains the command, its
parameters, and a descriptive command name. The general command
description identifies in broad terms the function of the command and when to use
it. The detailed command description breaks down the effect of each of the
parameters' values. This section may also contain supplementary information
needed for proper usage of the command.
The modem or data circuit terminating equipment (DCE) returns at least one
result code for each command submitted to it by the host system or data terminal
equipment (DTE). Conditions for receiving the result code follow the listed result
code.
Use this command to instruct the modem to echo characters sent to it. When the
echo feature is selected, characters sent to the modem are sent back to the host
and displayed on the monitor.
OK if <value> = 0—1.
ERROR if <value> does not equal 0—1.
