`chat STRINGS'
`chat-timeout NUMBER'
`chat-fail STRING'
`chat-seven-bit BOOLEAN'
`chat-program STRINGS'
     These commands describe a chat script to use when logging on to a
     remote system.  This login chat script is run after any chat
     script defined in the `dial' file (see dial File.).  Chat
     scripts are explained in See Chat Scripts.

     Two additional escape sequences may be used in send strings.

    `\L'
          Send the login name, as set by the `call-login' command.

    `\P'
          Send the password, as set by the `call-password' command.

     Three additional escape sequences may be used with the
     `chat-program' command.  These are `\L' and `\P', which become the
     login name and password, respectively, and `\Z', which becomes the
     name of the system of being called.

     The default chat script is:

          chat "" \r\c ogin:-BREAK-ogin:-BREAK-ogin: \L word: \P

     This will send a carriage return (the `\c' suppresses the
     additional trailing carriage return that would otherwise be sent)
     and waits for the string `ogin:' (which would be the last part of
     the `login:' prompt supplied by a Unix system).  If it doesn't see
     `ogin:', it sends a break and waits for `ogin:' again.  If it
     still doesn't see `ogin:', it sends another break and waits for
     `ogin:' again.  If it still doesn't see `ogin:', the chat script
     aborts and hangs up the phone.  If it does see `ogin:' at some
     point, it sends the login name (as specified by the `call-login'
     command) followed by a carriage return (since all send strings are
     followed by a carriage return unless `\c' is used) and waits for
     the string `word:' (which would be the last part of the
     `Password:' prompt supplied by a Unix system).  If it sees
     `word:', it sends the password and a carriage return, completing
     the chat script.  The program will then enter the handshake phase
     of the UUCP protocol.

     This chat script will work for most systems, so you will only be
     required to use the `call-login' and `call-password' commands.  In
     fact, in the file-wide defaults you could set defaults of
     `call-login *' and `call-password *'; you would then just have to
     make an entry for each system in the call-out login file.

     Some systems seem to flush input after the `login:' prompt, so they
     may need a version of this chat script with a `\d' before the
     `\L'.  When using UUCP over TCP, some servers will not be handle
     the initial carriage return sent by this chat script; in this case
     you may have to specify the simple chat script `ogin: \L word: \P'.

`call-login STRING'
     Specify the login name to send with `\L' in the chat script.  If
     the string is `*' (e.g., `call-login *') the login name will be
     fetched from the call out login name and password file (
see Configuration File Names.).  The string may contain escape
     sequences as though it were an expect string in a chat script
     (see Chat Scripts.).  There is no default.

`call-password STRING'
     Specify the password to send with `\P' in the chat script.  If the
     string is `*' (e.g., `call-password *') the password will be
     fetched from the call-out login name and password file (
see Configuration File Names.).  The string may contain escape
     sequences as though it were an expect string in a chat script
     (see Chat Scripts.).  There is no default.
