Two-Wire Dial (Hayes) mode is the factory-default configuration for the
Modem. Hayes mode operation and commands are explained in detail in 5.0,
Hayes Emulation Mode.
Dialing a Phone Number. To dial a telephone number in Hayes mode,
type the Hayes command
AT D on your computer or terminal keyboard, followed by the number
you want to call and <cr>. Example:
AT D 5551212 <cr>
Dashes or spaces may be included for clarity, but they are not necessary.
The Modem ignores them.
A carriage return (<cr>) is required at the end of each command. On
most keyboards, the carriage return (<cr>) key is labeled Enter or Return.
In response to the command line shown above, the Modem will dial the
number 555-1212.
If you need an access code (such as 9) to dial out of your building,
insert the access code and a comma in the dial string:
AT D 9,5551212 <cr>
The Modem pauses for 2 seconds at the comma. This allows the Modem to
wait for a second dial tone (after the access code) before dialing the number.
