Setting Up your Modem | Telenetics 56 instruction

Dumb Mode Operation

Your modem has two methods of operating with your computer. The commonly used method is “smart mode”, where the computer issues “AT” commands to the modem to make it dial and hang up For computers which do not offer an asynchronous port or cannot communicate synchronously using V.25bis commands, dumb mode permits manual control of your modem.

Selecting Dumb Mode on Desktop Modems

To select Dumb mode:

•Place front panel Option switch 4 in the Down position

To select Smart mode:

•Place front panel Option switch 4 in the Up position The Option Switches and Mode and Talk/Data buttons

Some modems also have rear panel Option switches — check the rear panel of your modem.

HINT To restore the factory settings of your modem, switch it on holding the Mode button in, until the modem “beeps” twice.

Setting Up your Modem

In most instances, your modem will need to be configured prior to entering Dumb mode. All configuration of your modem is performed using the AT commands.

For example, if you wish to have your modem dial a stored telephone number when the computer asserts (or “raises”) the DTR signal, you must first store the telephone number in the modem and select stored number dialling operation, using the AT commands.

Selecting Communications Speeds

If you are dialling in Dumb mode, the communication speed it uses is dependant upon the setting of the front panel Mode LEDs. To change the speed at which your modem connects after dialling:

•Place front panel Option switches 3 and 4 in the Down position (disable auto-answering, select Dumb mode)

•Press the Mode button (located next to the front panel Option switches) until the correct speed is indicated on the front panel Mode LEDs

☞Your modem cannot dial if auto-answer is enabled.
