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 19,200bps: 
   ACU tty1A - 19200 hayes2400

NOTE: If you intend to use an outgoing PPP link over a modem that uses the ``hayes2400'' 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(F) manual page for more information.
