UUCICO(C)                XENIX System V                 UUCICO(C)



     Name
          uucico - Executes work files for uucp data transmission.

     Syntax
          uucico [ options ] ...

     Description
          The uucico program performs the following major functions:

          - Scan the spool directory for work.

          - Place a call to a remote site.

          - Negotiate a line protocol to be used.

          - Execute all requests from both sites.

          - Log work requests and work completions.

          uucico may be started by a system daemon such as cron(C), by
          the user (usually for testing), or by a remote site.

     Options
          The uucico program must generally be started directly by the
          user or by another program, such as a shell script invoked
          by cron . There are several options used for execution:

          -r1  Start the program in MASTER mode.  This is used when
               uucico is started by a program or cron shell.

               In MASTER mode, a connection is made to a remote site.
               MASTER mode operates in one of two ways.  If no site
               name is specified (the -s option not specified), the
               program scans the spool directory for sites to call.
               If a site name is specified, that site is called, and
               work is only done for that site.

               If started by a remote site, the program is considered
               to be in SLAVE mode.

          -ssitename
               Do work only for site sitename . If -s is specified, a
               call to the specified site is made even if there is no
               work for site sitename in the spool directory, but call
               only when times in the L.sys file permit it.  This is
               useful for polling sites that do not have the hardware
               to initiate a connection.

          -Ssitename
               Do work only for site sitename . If -S is specified, a
               call to the specified site is made even if there is no
               work for the site in the site in the spool directory.

               Unlike -s, this option ignores the call times for the
               sitename given in the L.sys file.

          The following options are used primarily for debugging:

          -ddir
               Use directory dir for the spool directory.

          -xnum
               Use num (1-9) as the level of debugging output.  9
               specifies the highest level of debugging.

          The next section describes the major steps within the uucico
          program.

     Notes
          The uucico program should be specified as the shell field in
          the /etc/passwd file for the uucp logins.

          If you want your machine to immediately forward files from a
          remote machine to other machines, the command
          /usr/lib/uucp/uucico must be present in the L.cmds file.
          Otherwise, files will be forwarded the next time your
          machine connects with the remote machine.

          On a dial-in site, uucico is always started whenever a
          calling site logs in.

          However, on a dial-out site, uucico is only started when
          explicitly invoked.
