HOW TO USE THIS MANUAL
This manual contains operating instructions for Courier Dual
Standard V.34 and Courier V.34 modems.
These modems have many similar features except for the
signaling they use to connect with remote modems at high
speeds: V.32/V.32 terbo, HST, V.FC, or V.34. Courier HST Dual
Standard modems use any type of signaling, depending on the
type of remote modem. V.34 modems can connect at rates up to
28.8K bps.

How to Use This Manual iii
A NOTE ON COMMUNICATIONS SOFTWARE
If you're using a computer rather than a terminal, you need
communications software. Many brands are available, all of
which are based on the modem's AT command set.
Some users prefer their communications software to take
control of the modem, and are more comfortable with a
program that makes the modem almost transparent. Others
prefer a program that allows them to use the modem's AT
command set sometimes, and their software at other times,
depending on the task at hand. Review at least Chapter 4 so
that you have a basic understanding of the modem's require-
ments and operation.
