enter an &F command from the terminal or initialize
the modem through the front panel switches.
You can modify and save the current operating

new configuration is retrieved, its settings replace the
current operating parameters. Refer to Chapter 5, AT

Commands and Registers
The T3000 modem is equipped with commands and
registers that you can set to meet the specific
requirements of your data communications system.
The T3000 modem currently supports the Telebit
Extended AT command set.
You may enter a command line of up to 80 characters
in uppercase or lowercase. 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,
backspace over the mistake, then retype the line. You
cannot backspace over the AT prefix because it is
interpreted immediately after being typed.
