NAME
     uucico - file transport program for the uucp system

SYNOPSIS
     /usr/lib/uucp/uucico [-r role] [-x level] [-i iface] [-d spool_dir]
          -s system_name

DESCRIPTION
     uucico is the file transport program for uucp work file transfers.  Role
     numbers for the -r are the digit 1 for master mode or 0 for slave mode
     (default).  The -r option should be specified as the digit 1 for master
     mode when uucico is started by a program or cron.  uux and uucp both
     queue jobs that will be transferred by uucico. It is normally started by
     the scheduler, uusched, but can be started manually; this is done for
     debugging.  For example, the shell uutry starts uucico with debugging
     turned on.  A single digit must be used for the -x option with higher
     numbers for more debugging.

     The -i option defines the interface used with uucico.  This interface
     only affects slave mode.  The known interface is UNIX.

     The device names, dialers, and so forth in /usr/lib/uucp/Devices must be
     correct.  The device names used by uucp, such as /dev/ttym3, must be
     readable and writable by the "user" uucp.

     Before starting to transfer a file, uucico checks to see if the file
     /etc/nologin exists.  If it does, the connection is broken.

     Any user name under which uucico runs (any "user" with
     /usr/lib/uucp/uucico as its shell in /etc/passwd) must be no more than 8
     characters long.  This restriction is a result of the nature of the
     /var/adm/utmp file.  System-names longer than 8 characters generally do
     not work because of UUCP protocol restrictions.  In both cases, one tends
     to suffer strange "permission problems."
