Configuring terminal line settings

Checking modem settings

To ensure that a modem is optimally configured:

  1. Examine the file /etc/uucp/Dialers for an entry to be used for your modem (see Dialers(4bnu)). Try to locate an entry that is specific to your modem (check the entry labels for your modem name). If you cannot find one, select the one that matches most closely. Normally, an acceptable entry is ``hayes''. Most, if not all, available modems support Hayes compatibility.

  2. Most modems have dip switches or other selectable settings already set to the defaults needed for standard network communication. Modems also accept configuration commands that address firmware settings. Consult your modem manual for the correct settings and the appropriate commands for making changes if there is a need.

  3. Make sure that the default modem settings do not conflict with the Dialers entry you select. This is especially important if someone else has used the modem before you got it. If you run into problems, or if the stated settings are apparently in conflict, make the change that is appropriate. To do this, do not modify the Dialers entry. Change the switches or use modem commands to change the firmware settings.

  4. Note that firmware automatically reverts to the default settings each time you power on and off. You may set new defaults by using the ``configuration set'' feature available on most modems. Consult your modem manual if you need to reset defaults. Configuration setting is a chore often performed by communications packages. However, even if you set your modem directly (referencing the port), you have the ability to call up this feature.
