AT Command Descriptions
5
This chapter describes the Telebit Extended AT
commands used when the T3000 modem is operating
in command mode. Chapter 6, AT Register
Descriptions, contains complete descriptions of the
registers.
You may enter a command line of up to 80 characters
in upper or lower case. You must precede the first
command in the line with an AT or
at
and follow the
last command by pressing the return key.
If you make an error while typing a command,
simply backspace over the mistake then retype the
line. You cannot backspace over the AT prefix
because it is interpreted immediately after being
typed.
Command Syntax
A comma (,) used between commands causes the
system to pause for the amount of time specified by
the S8 register.
You can repeat the last command line issued by
entering Al or a/. Because it also repeats the AT
prefix and the carriage return, do not enter the AT
prefix or a carriage return when using this command.
You can add blanks and tabs to enhance readability.
The notation (n) in the command descriptions
represents a decimal numeric option. The option
immediately follows the command.
