Modem Commands

AT? Menu Mode

This command allows you to use a menu system to configure the modem. There are many

extended modes of operation only available from the menu, the protocol settings for example.

After you exit the menu through the Escape key the modem will return to the command mode.

This menu command is more versatile than the one brought up by the front panel button because

it works for any serial port settings (as long as the modem and terminal software have the same

settings).

ATD Dial

This command allows you to dial a telephone number. The basic dialing command is:

ATDXXXX:YY

ATD followed by the remote modem Rx address (XXXX) and port number (YY).

For Example:

To dial the number 2356 78

Type: ATD2356 78 <CR>

You may use hyphens or spaces. They will be ignored by the modem, but they will make it easier

to read the command line.

For example:

Type: ATD 2356-78 <CR>

☞ D command must be the final command on a command line.

ATE Echo

The E command allows you to select whether the characters you type at your keyboard (while in

the local command state) will be echoed back to your computer screen by the modem.

Command Description

ATE0 Disable local command state echo

ATE1 Enable local command state echo

ATH Hang Up

The H command forces the modem to hang up.

Command Description

ATH0 Hang up
