Introduction
This chapter presents a command summary followed by a detailed description of each command used in the MultiMux.
Each command line must begin with a prefix of AT and 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 (&W) 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 1is shown
in the following example. The example 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 described in Appendix D.
The following functional grouping of the commands are listed with their paragraph title and paragraph number:
