Using Your Modem

This chapter highlights some of the basic functions and
commands necessary to operate your modem. Whether you
consider yourself a novice or an experienced user in data
communications, you may want to read through some of the
examples to become familiar with your modem's operation.

Using AT Commands

The KeepInTouch Card modem uses AT commands and
S-Registers to control its operation and firmware configuration.
These commands are issued from your computer through your
communications software package.
Your modem is compatible with the standard Hayes AT
command set, the most common commands used throughout
the industry, and also uses what is known as an extended AT
command set: those commands unique to the KeepInTouch
Card modem. All of these commands are listed in Chapter 4, AT
Command Set and S-Registers.
Please review the following guidelines before using any AT
Commands.
G
AT commands must be entered while the modem is in
either Command mode or online Command mode.
The escape sequence (+++) is used to enter online
Command mode from Data mode. (For more
information, refer to the Operating Modes (Command
and Data) section found later in this chapter.)
G
All commands (except A/ (repeat last command) and
+++ (escape sequence)) must begin with the characters
AT and end by pressing the Enter key.
