SYSTEMS(F)                           UNIX System V



     Name
          systems - format of UUCP Systems file


     Description
          The  Systems  file  (/usr/lib/uucp/Systems)   contains   the
          information  needed  by  the  uucico  daemon  to establish a
          communication link to a remote computer.  Each entry in  the
          file represents a computer that your computer can call.  You
          can configure  the  Systems  file  to  prevent  unauthorized
          computers  from  logging  in on your computer. More than one
          entry may be  present  for  a  particular  computer.   These
          additional entries represent alternative communication paths
          which the computer tries in sequential order.

          Each entry in the Systems file has the following format:
          sitename schedule device speed phone login-script

               sitename   field contains the node name of  the  remote
                          computer.

               schedule   field is a string that  indicates  the  day-
                          of-week  and  time-of-day  when  the  remote
                          computer can be called.

               device     is the device type that should  be  used  to
                          establish  the  communication  link  to  the
                          remote computer.

               speed      indicates the transfer speed of  the  device
                          used in establishing the communication link.

               phone      provides the  phone  number  of  the  remote
                          computer for automatic dialers.  If you wish
                          to create a portable Systems file  that  can
                          be  used  at  a  number  of  sites where the
                          dialing    prefixes    differ,    see    the
                          dialcodes(F) man page.

               login-scripcontains login information (also known as  a
                          ``chat script'').
