Configuring terminal line settings

Referencing the port

To access a modem directly:

  1. Examine the file /etc/uucp/Dialers (see Dialers(4bnu)) for an entry to be used for a ``direct'' connection. The label will be ``direct'' or ``direct_modem''. Note which label is used, since it must be the same in the /etc/uucp/Devices file.

  2. Examine the file /etc/uucp/Devices (see Devices(4bnu)) to be sure that there is a direct entry for the port where your modem is attached.

    The correct device name for a device on COM1 is one of ``term/00'', ``term/00s'', ``term/00h'', ``tty1a'' or ``tty1A''.

    The correct device name for a device on COM2 is one of ``term/01'', ``term/01s'', ``term/01h'', ``tty2a'', ``tty2A''.

    Note that the logical device names point to separate drivers. These differ based on the baud rate and UART values. See asyc(7) for information on the driver you need and how to establish the appropriate reference in the Devices file. If there is no entry for your requirements, add the port as a direct line in /etc/uucp/Devices using either the direct or direct_modem label, depending on the label found in the Dialers file, for example:

    Direct term/00 - Any direct_modem

  3. Use the cu(1bnu) command to access the modem, for example:

    cu -l term/00

  4. When the direct connection is established (cu executes successfully), you can enter AT (Attention) data communications commands as well as modem configuration commands specific to your modem software.
