COMPLETE HAYES COMMANDS
The Intele–Modem uses the complete industry-standard Hayes command set, except that
there are no self-test commands. Additional commands have been added for the Baudot
code settings. If the command has a default, it's listed after the name of the command.
Hayes commands are also known as AT commands because each command must be
preceded by the letters AT. Both letters must be entered in upper or lower case (at or AT).
The modem will not recognize an upper case A and a lower case t (At) or the reverse (aT).
AT is also a command by itself which is used to switch from on-line to command mode.
How to type commands______________________________________
You must use your communications software to get into terminal (or talk) mode. Each
command has three parts–the AT prefix, the command itself, and the Enter Key. You can
enter each command separately after its own AT prefix:
ATB1 [Enter]
ATF0 [Enter]
ATD5551212 [Enter]
or string them together after a single AT:
ATB1F0D5551212 [Enter]
You can type commands in a solid string of characters, as shown above, or you can put
spaces between command characters to make them easier to read.
AT B1 D 555 1212 [Enter]
If you make a mistake, use the Backspace Key to make corrections before you press the
Enter Key.
Press the Enter Key when you have typed all the command characters you want to use.
When you press the Enter Key, the Intele–Modem carries out your commands.
Default settings_____________________________________________
When you turn your Intele–Modem on, it's automatically set to communicate in a specific
way, called its default settings. If a command has a default setting, it's shown in
parentheses after the name of the command.
