Chapter 2 describes the format to use when typing modem commands. Chapter 2 also
describes the responses that your modem sends to your computer screen when you
execute, or try to execute, modem commands.
If you will be using a communication software program to make data calls, you will
probably not need to type commands, because your software program will handle these
tasks for you. Similarly, you will probably not see the responses because your software
program may intercept them.
However, if you perform data activities directly with your modem, you will find the format
for typing modem commands and modem response helpful.
2.1 Typing a command
Using commands, you can have your modem perform a variety of activities, such as
dialing or answering a data call or sending a fax. In order to send commands to your
modem, You must type a command line while your modem is in command mode.
2.2 To type a command line :
1. Type
AT.
These characters must precede every command line. (except when you type
the A/ command, described on page 30)
2. Type the commands you want your modem to execute. A command line can contain
up to 40 characters.
3. Press the Enter key. The modem will then execute the commands on the command
line.
2.3 Correcting a typing mistake
If you make a mistake while typing a command, press the Backspace key to delete the
error. You can delete every command except
AT
.
2.4 Readability
To make a command line easy to read, you can insert spaces parentheses, hyphens, and
other punctuation in your command line. For example :
AT M3 DT 9, 1(818)555-1234
Your modem ignores spaces and punctuation when executing a command line, but these
characters apply to the 40 characters limit.
2.5 Typing more than 40 characters
If you want to type more than 40 characters on a command line, type a regular command
line (up to 40 characters long) and end it with a semicolon as the last character. When
