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.
