Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes

Storing a Telephone Number

To store a telephone number, type &Zn=x in terminal mode, where n is the number of the

memory register in which the number is to be stored, and x is the dial command string

that you want to store. For example, type AT&Z9=612-785-3500 <cr> to store the

number 612-785-3500 in memory register 9.

Dialing a Stored Telephone Number

To dial a stored telephone number, type DS=n in terminal mode, where n is the location

of the number you want to dial. For example, type ATDS=3 <cr> dials a telephone stored

in memory register 3 location.

Displaying a Stored Number

To display a stored telephone number, type &Zn? in terminal mode, where n is the

memory register where the number is stored. For example, type AT&Z5? <cr> to display

the telephone number in memory register 5. To list all ten telephone numbers stored in

memory, type ATL <cr>.

Answering a Call

You can answer incoming calls to the TA either manually or automatically. When the TA

detects an incoming call, it turns on the RI signal on the V.24 interface and sends a RING

result code to the computer or terminal after each ring. If you enable autoanswer, the TA

automatically answers the call. To manually answer the call, use the A command.

Answering Manually

If your communication program is in terminal mode when the RING result code appears

on your monitor, manually answer the call by typing ATA <cr>.

Answering Automatically

To set the TA to answer a call automatically :

1. Enable autoanswer by setting register S0 to the ring on which you want the TA to

answer (e.g., in terminal mode, type S0=4 to make the TA answer on the fourth ring).

You also can use one of the configuration utilities to the turn autoanswer on and set

the number of rings.

2. Make sure that the TA is offline.

The TA answers the call after the number of rings specified by S0. To disable autoanswer,

use a configuration utility or the command S0=0.

Note: If the user wants to accept calls while DTR is low, the TA must be configured to

ignore DTR. To ignore, enter AT&D0<cr>. With this configuration, the TA can accept

calls while DTR is low. If this configuration setting is not made, the TA rejects incoming

calls until DTR is high while the calls comes in.

Hanging Up

To hang up a call, first escape to online command mode (+++AT<cr>), then enter the H

command (ATH<cr>). The escape sequence and hang up command can be combined into

one command string: +++ATH<cr>.
