5.1 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
