Adding and configuring modems

Using /etc/uucp/Dialers

If you are not using atdialer(1bnu) and mdmcfg(1M), use a dialer that is an entry in /etc/uucp/Dialers. To do this:

Edit /etc/uucp/Devices to enter the correct speed range and inbuilt dialer, Dialer file entry, or the name of a dialer program used by the modem. See Devices(4bnu) for more information.
Obtain and configure a suitable dialer program for your modem.
If a modem configuration does not exist, or /etc/uucp/Dialers does not contain a suitable entry, you must create one or the other.

See ``Administering BNU'' for more information.

Dialers file entries

``Dialers file entries'' lists dialer types that are available as Dialers entries.

NOTE: This is not the preferred method of configuring a modem.

If you are experimenting with an unsupported modem, the ``hayes2400'' entry in the Dialers file is a good starting point; it can be used even with high-speed modems. The following example Devices entry is for a modem that uses a Dialers file entry but operates at 19200bps:

   ACU term/00m - 19200 Hayes_Compatible_2400

NOTE: If you intend to use an outgoing PPP link over a modem that uses the ``Hayes_Compatible_2400'' entry in the Dialers file, change the word Speed to CONNECT.

The following Dialers file entry, standard, should also be suitable for many V.32bis and higher speed modems:

standard	=W-,  "" AT&F1  OK\r  ATB0M1X4  OK\r  ATDT\T\r\c  CONNECT

Although it is possible to create or modify an entry in the Dialers file yourself, the syntax can be difficult to follow. Consult the Dialers(4bnu) manual page for more information.
