uucico Description
------------------

     uucico [options]

   The `uucico' daemon processes file transfer requests queued by
`uucp' and `uux'.  It is started when `uucp' or `uux' is run (unless
they are given the `-r' or `--nouucico' options).  It is also typically
started periodically using entries in the `crontab' table(s).

   When `uucico' is invoked with `-r1', `--master', `-s', `--system',
or `-S', the daemon will place a call to a remote system, running in
master mode.  Otherwise the daemon will start in slave mode, accepting
a call from a remote system.  Typically a special login name will be
set up for UUCP which automatically invokes `uucico' when a remote
system calls in and logs in under that name.

   When `uucico' terminates, it invokes the `uuxqt' daemon, unless the
`-q' or `--nouuxqt' options were given; `uuxqt' executes any work
orders created by `uux' on a remote system, and any work orders created
locally which have received remote files for which they were waiting.

   If a call fails, `uucico' will normally refuse to retry the call
until a certain (configurable) amount of time has passed.  This may be
overriden by the `-f', `--force', or `-S' options.

   The `-l', `--prompt', `-e', or `--loop' options may be used to force
`uucico' to produce its own prompts of `login: ' and `Password:'.  When
another `uucico' daemon calls in, it will see these prompts and log in
as usual.  The login name and password will normally be checked against
a separate list kept specially for `uucico', rather than the
`/etc/passwd' file (see Configuration File Names.).  It is
possible, on some systems, to configure `uucico' to use `/etc/passwd'.
The `-l' or `--prompt' options will prompt once and then exit; in this
mode the UUCP administrator, or the superuser, may use the `-u' or
`--login' option to force a login name, in which case `uucico' will not
prompt for one.  The `-e' or `--loop' options will prompt again after
the first session is over; in this mode `uucico' will permanently
control a port.

   If `uucico' receives a `SIGQUIT', `SIGTERM' or `SIGPIPE' signal, it
will cleanly abort any current conversation with a remote system and
exit.  If it receives a `SIGHUP' signal it will abort any current
conversation, but will continue to place calls to (if invoked with
`-r1' or `--master') and accept calls from (if invoked with `-e' or
`--loop') other systems.  If it receives a `SIGINT' signal it will
finish the current conversation, but will not place or accept any more
calls.
