Accepting a Call
----------------

`called-login STRINGS'
     The first STRING specifies the login name that the system must use
     when calling in.  If it is `ANY' (e.g., `called-login ANY') any
     login name may be used; this is useful to override a file-wide
     default and to indicate that future alternates may have different
     login names.  Case is significant.  The default value is `ANY'.

     Different alternates (see Defaults and Alternates.) may use
     different `called-login' commands, in which case the login name
     will be used to select which alternate is in effect; this will
     only work if the first alternate (before the first `alternate'
     command) uses the `called-login' command.

     Additional strings may be specified after the login name; they are
     a list of which systems are permitted to use this login name.  If
     this feature is used, then normally the login name will only be
     given in a single `called-login' command.  Only systems which
     appear on the list, or which use an explicit `called-login'
     command, will be permitted to use that login name.  If the same
     login name is used more than once with a list of systems, all the
     lists are concatenated together.  This feature permits you to
     restrict a login name to a particular set of systems without
     requiring you to use the `called-login' command for every single
     system; you can achieve a similar effect by using a different
     system file for each permitted login name with an appropriate
     `called-login' command in the file-wide defaults.

`callback BOOLEAN'
     If BOOLEAN is true, then when the remote system calls `uucico'
     will hang up the connection and prepare to call it back.  The
     default is false.

`called-chat STRINGS'
`called-chat-timeout NUMBER'
`called-chat-fail STRING'
`called-chat-seven-bit BOOLEAN'
`called-chat-program STRINGS'
     These commands may be used to define a chat script (*note Chat
     Scripts::.) that is run whenever the local system is called by the
     system being defined.  The chat script defined by the `chat'
     command (see Logging In.), on the other hand, is used when the
     remote system is called.  This called chat script might be used to
     set special modem parameters that are appropriate to a particular
     system.  It is run after protocol negotiation is complete, but
     before the protocol has been started.  For additional escape
     sequence which may be used besides those defined for all chat
     scripts, see See Logging In.  There is no default called chat
     script.  If the called chat script fails, the incoming call will
     be aborted.
