NAME
       wvdial - PPP dialer with built-in intelligence.

SYNOPSIS
       wvdial [ OPTIONS ] [ SECTION ] ...

DESCRIPTION
       wvdial  is  an intelligent PPP dialer, which means that it dials a modem and starts PPP in
       order to connect to the Internet.  It is something like the chat(8) program,  except  that
       it  uses  heuristics to guess how to dial and log into your server rather than forcing you
       to write a login script.

       When wvdial starts, it first loads its configuration from /etc/wvdial.conf and ~/.wvdialrc
       which  contains basic information about the modem port, speed, and init string, along with
       information about your Internet Service Provider (ISP), such as	the  phone  number,  your
       username, and your password.

       Then  it initializes your modem and dials the server and waits for a connection (a CONNECT
       string from the modem).	It understands and responds to typical connection problems  (like
       BUSY and NO DIALTONE).

       Any  time  after  connecting,  wvdial  will  start  PPP if it sees a PPP sequence from the
       server.	Otherwise, it tries to convince the server to start PPP by doing the following:

       o   responding to any login/password prompts it sees;

       o   interpreting "choose one of the following"-style menus;

       o   eventually, sending the word "ppp" (a common terminal server command).

       If all of this fails, wvdial just runs pppd(8) and hopes for the best. It  will	bring  up
       the connection, and then wait patiently for you to drop the link by pressing CTRL-C.

OPTIONS
       Several options are recognized by wvdial.

       -c, --chat
	      Run  wvdial  as  a  chat	replacement  from within pppd, instead of the more normal
	      method of having wvdial negotiate the connection and then call pppd.

       -C, --config=CONFIGFILE
	      Run wvdial with CONFIGFILE as the configuration file, instead of	/etc/wvdial.conf.
	      This is mainly useful only if you want to have per-user configurations, or you want
	      to avoid having dial-up information (usernames, passwords,  calling  card  numbers,
	      etc.) in a system wide configuration file.

       --remotename
	      Override the Remote Name setting in the dialer configuration section of the config-
	      uration file. This is mainly useful when you dial to multiple systems with the same
	      user name and password, and you don't want to use inheritance to override this set-
	      ting (which is the recommended way to do it).

       -n, --no-syslog
	      Don't output debug information to the syslog  daemon  (only  useful  together  with
	      --chat).

       wvdial is normally run without command line options, in which case it reads its configura-
       tion from the [Dialer Defaults] section of /etc/wvdial.conf.  (The configuration  file  is
       described in more detail in wvdial.conf(5) manual page.)

       One  or	more SECTIONs of /etc/wvdial.conf may be specified on the command line.  Settings
       in these sections will override settings in [Dialer Defaults].

       For example, the command:
	      wvdial phone2
       will read default options from the [Dialer Defaults] section, then override any or all  of
       the options with those found in the [Dialer phone2] section.

       If  more  than  one  section is specified, they are processed in the order they are given.
       Each section will override all the sections that came before it.

       For example, the command:
	      wvdial phone2 pulse shh
       will read default options from the [Dialer Defaults] section, then override any or all  of
       the  options  with  those  found  in  the [Dialer phone2] section, followed by the [Dialer
       pulse] section, and lastly the [Dialer shh] section.

       Using this method, it is possible to easily configure wvdial to switch  between	different
       internet  providers,  modem  init strings, account names, and so on without specifying the
       same configuration information over and over.

BUGS
       "Intelligent" programs are frustrating when they don't work right.  This version of wvdial
       has  only minimal support for disabling or overriding its "intelligence", with the "Stupid
       Mode", "Login Prompt", and "Password Prompt" options.  So, in general if you have  a  nice
       ISP, it will probably work, and if you have a weird ISP, it might not.

       Still,  it's not much good if it doesn't work for you, right?  Don't be fooled by the fact
       that wvdial finally made it to version 1.00; it could well contain many bugs  and  misfea-
       tures.  Let us know if you have problems by sending e-mail to <wvdial-list@lists.nit.ca>.

       You   may   encounter   some   error   messages	 if   you  don't  have	write  access  to
       /etc/ppp/pap-secrets and /etc/ppp/chap-secrets.	Unfortunately, there's really no nice way
       around this yet.

FILES
       /etc/wvdial.conf
	      Configuration  file  which  contains  modem,  dialing,  and  login information. See
	      wvdial.conf(5).

       /dev/ttyS*
	      Serial port devices.

       /etc/ppp/peers/wvdial
	      Required for correct authentication in pppd version 2.3.0 or newer.

       /etc/ppp/{pap,chap}-secrets
	      Contains a list of usernames and passwords used by pppd for authentication.  wvdial
	      maintains this list automatically.

AUTHORS
       Dave  Coombs  and  Avery Pennarun for Net Integration Technologies.  We would also like to
       thank SuSE and RedHat for adding a number of various  cool  features  to  wvdial.   Thanks
       guys!
