Introduction

This chapter presents a command summary followed by a detailed
description of each command used in the MultiMux. The structure of the
commands is that they all begin with the prefix AT. Each command line
may contain any number of commands in a string (no spaces) up to a
limit of 40 characters. Most commands include a value and are part of
the 40 character total. Hitting Return executes a command line but does
not incorporate it into the operation of your MultiMux. You must execute
a Store New Parameters command to implement your changes into your
mux network.
An example of a command line which changes the parameters of the
channel device connected to channel 1. The following command
changes the baud rate to 4800 bps, parity to odd, CTS flow control and
turns echo off.
Table 5-1 presents a summary of all the commands used in the
MultiMux. The commands are divided into a number of general
categories according to their functionality within the MultiMux. This
functional division is carried on into the detailed description of each
command.
The access commands for the command modem are described in this
chapter. The general AT commands for the command modem are
