NAME
       uucico - UUCP file transfer daemon

SYNOPSIS
       uucico [ options ]

DESCRIPTION
       The  uucico  daemon processes file transfer requests queued by uucp (1)
       and uux (1).  It is started when uucp or uux is run  (unless  they  are
       given  the -r option).  It is also typically started periodically using
       entries in the crontab table(s).

       When 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 automati-
       cally invokes uucico when a call is made.

       When uucico terminates, it invokes the uuxqt (8) daemon, unless the  -q
       or  --nouuxqt  option is given; uuxqt (8) executes any work orders cre-
       ated by uux (1) 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  overri-
       den by the -f, --force, or -S option.

       The  -l, --prompt, -e, or --loop options may be used to force uucico to
       produce its own prompts of "login: "  and  "Password:".	 When  another
       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; it is
       possible on some systems to direct uucico to use the /etc/passwd	 file.
       The  -l or --prompt option 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 option 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.

OPTIONS
       The following options may be given to uucico.

       -r1, --master
	    Start in master mode (call out to a system); implied by -s, --sys-
	    tem, or -S.	 If no system is specified, call any system for	 which
	    work is waiting to be done.

       -r0, --slave
	    Start in slave mode.  This is the default.

       -s system, --system system
	    Call the named system.

       -S system
	    Call the named system, ignoring any required wait.	This is equiv-
	    alent to -s system -f.

       -f, --force
	    Ignore any required wait for any systems to be called.

       -l, --prompt
	    Prompt for login name and password	using  "login:	"  and	"Pass-
	    word:".   This allows uucico to be easily run from inetd (8).  The
	    login name and password are	 checked  against  the	UUCP  password
	    file,  which  probably  has no connection to the file /etc/passwd.
	    The --login option may be used to force a  login  name,  in	 which
	    cause uucico will only prompt for a password.

       -p port, --port port
	    Specify a port to call out on or to listen to.

       -e, --loop
	    Enter endless loop of login/password prompts and slave mode daemon
	    execution.	The program will not stop by itself; you must use kill
	    (1) to shut it down.

       -w, --wait
	    After calling out (to a particular system when -s, --system, or -S
	    is specifed, or to all systems which have work when	 just  -r1  or
	    --master is specifed), begin an endless loop as with --loop.

       -q, --nouuxqt
	    Do not start the uuxqt (8) daemon when finished.

       -c, --quiet
	    If	no calls are permitted at this time, then don't make the call,
	    but also do not put an error message in the log file  and  do  not
	    update the system status (as reported by uustat (1)).  This can be
	    convenient for automated polling scripts, which may want to simply
	    attempt to call every system rather than worry about which partic-
	    ular systems may be called at the moment.  This option  also  sup-
	    presses  the  log  message	indicating that there is no work to be
	    done.

       -C, --ifwork
	    Only call the system named by -s, --system or -S if there is  work
	    for that system.

       -D, --nodetach
	    Do	not  detach  from  the	controlling terminal.  Normally uucico
	    detaches from the terminal before each call out to another	system
	    and before invoking uuxqt.	This option prevents this.

       -u name, --login name
	    Set	 the  login  name to use instead of that of the invoking user.
	    This option may only be used by  the  UUCP	administrator  or  the
	    superuser.	 If  used  with	 --prompt,  this  will cause uucico to
	    prompt only for the password, not the login name.

       -z, --try-next
	    If a call fails after the remote system is reached, try  the  next
	    alternate rather than simply exiting.

       -i type, --stdin type
	    Set	 the  type of port to use when using standard input.  The only
	    support port type is TLI, and this is only available  on  machines
	    which  support  the	 TLI  networking  interface.  Specifying -iTLI
	    causes uucico to use TLI calls to perform I/O.

       -x type, -X type, --debug type
	    Turn on particular debugging types.	 The following types are  rec-
	    ognized:  abnormal, chat, handshake, uucp-proto, proto, port, con-
	    fig, spooldir, execute, incoming, outgoing.

	    Multiple types may be given, separated by commas, and the  --debug
	    option  may	 appear	 multiple  times.  A number may also be given,
	    which will turn on that many types from the	 foregoing  list;  for
	    example, --debug 2 is equivalent to --debug abnormal,chat.

	    The	 debugging  output is sent to the debugging file, which may be
	    printed using uulog -D.

       -I file, --config file
	    Set configuration file to use.  This option may not be  available,
	    depending upon how uucico was compiled.

       -v, --version
	    Report version information and exit.

       --help
	    Print a help message and exit.
