4. Commands
Most people use the communication software programs to tell modems what to do. Therefore, you may not
use the commands in this chapter. However, if you prefer to communicate with your modem directly, you can
type the commands described below.
4.1 Typing Commands
* Use the BACKSPACE key to delete typing errors.
* Every command (except A/ and +++) must begin with the AT or at prefix and be entered by pressing the
<Enter> key. For example, to execute the V command, you would type ATV and press the <Enter> key.
* When you see an n, replace the n with one of the letter or numeric options listed for that command.
For example, for the En command, you might type ATE1.
*All defaults are based on the &F Hardware Flow Control template load in NVRAM when the modem is
shipped.
